1.Cleanrooms: Fundamental Engineering Services for High-End Manufacturing

A cleanroom is an enclosed space designed to meet the requirements of product production processes, where contaminants in the air within a specific spatial range are controlled within a certain limit. By application field, industries that require cleanrooms during production or operation include: electronics industry, biopharmaceutical and medical industry, food industry, precision instruments, aerospace, etc. Different industries and production areas have varying requirements for cleanliness. From an industry perspective, the electronics industry (e.g., chip manufacturing, TFT-LCD (Thin Film Transistor Liquid Crystal Display), HDD (Hard Disk Drive)) has relatively high cleanliness requirements, while the pharmaceutical and food industries have lower cleanliness requirements. Taking China’s domestic demand as an example, China is strongly supporting high-end manufacturing, leading to robust demand for cleanroom engineering in the country. The market size has grown from RMB 76.755 billion in 2015 to RMB 214.614 billion in 2021, with an annualized growth rate consistently maintaining above 10%. We anticipate that this growth rate of over 10% will be sustained in the future.

2.Demand: Semiconductors, Grand Health, and New Energy Jointly Drive High Industry Growth

China strongly supports the development of high-end manufacturing, and downstream industries of cleanrooms—such as semiconductors and new energy—are supported by policies. As a critical link in high-end manufacturing, China has issued a large number of supportive industrial policies covering semiconductors, pharmaceuticals, clean energy, etc. The scale growth of these industries will further drive the development of the cleanroom industry.

2.1 Semiconductors: Computing Power Enhancement Driven by Informatization/AI

China is the world’s largest chip consumer market, but the market share of domestically produced chips has remained low for years. Recent changes in the international landscape have also boosted the demand for domestic substitution. In addition, with the continuous implementation of AI applications, the demand for computing power is expected to increase. According to IC Insights:

  • China’s chip market size was USD 143 billion in 2020 and is projected to reach USD 223 billion by 2025, with a compound annual growth rate (CAGR) of 9.3%.
  • The output value of chips manufactured in China was USD 22.7 billion in 2020 and is expected to reach USD 43.2 billion by 2025, with a high CAGR of 13.7%.

The continuous expansion of the (domestic) chip market scale may further drive capital expenditure, thereby promoting the growth of the cleanroom engineering industry.

2.2 Grand Health: Aging Population Spurs Medical and Health Demand to Drive Cleanroom Engineering Scale Long-Term

Due to the irreversible aging trend, the increase in the elderly population and the enhanced medical awareness of residents will likely boost medical demand, providing impetus for the development of grand health-related industries (e.g., pharmaceuticals, medical devices). According to Frost & Sullivan:

  • China’s pharmaceutical market will maintain rapid growth from 2021 to 2025, with the market size reaching RMB 2287.3 billion by 2025 and a CAGR of 9.6%.
  • The CAGR of China’s medical device market scale will reach 10.9% from 2020 to 2025, reaching RMB 1226.7 billion by 2025.

2.3 New Energy: Sustained Growth in PV Installed Capacity Drives Enterprise Capital Expenditure Expansion

The U.S. Inflation Reduction Act provides substantial subsidies for green industries whose main production links are completed within the U.S. The EU has established the European Solar Photovoltaic Industry Alliance to support Europe in achieving 30GW of domestic PV manufacturing capacity by 2025. China’s 14th Five-Year Plan for Renewable Energy Development sets a target that the total installed capacity of wind power and solar power will exceed 1.2 billion kilowatts by 2030, which will also drive capital expenditure growth of domestic enterprises and boost the cleanroom market.

3. Supply: Leading Enterprises Have Distinct Advantages, with Great Potential for Breakthrough in High-End Segments

The low-end market has a large number of enterprises, most of which are small in scale. In contrast, the mid-to-high-end market has a more favorable competitive landscape: leading enterprises have a long development history, advanced technology, rich project experience, and outstanding capabilities in undertaking mid-to-high-end projects. Cleanroom engineering enterprises have experienced supply expansion in recent years, but the number of newly added enterprises has slowed down since the 2020 pandemic. Relying on comprehensive strength advantages, leading enterprises have a higher proportion of mid-to-high-end projects, which helps build their own brands and makes them more likely to stand out. At this stage, considering that the cleanroom industry is still expected to maintain a high growth rate in the future, coupled with the potential capacity expansion driven by computing power demand under the impact of AI, the sector’s targets deserve attention.

4. Cleanrooms: Fundamental Engineering Services for High-End Manufacturing

The core goal of enterprises in building cleanrooms is to achieve precise control over the production environment. In essence, it is an enclosed space designed to adapt to the needs of product production processes, with the core function of limiting the concentration of contaminants in the air of a specific area within a preset range. Specifically, cleanrooms need to strictly regulate key environmental indicators such as air cleanliness, temperature, and humidity in the space, providing an environment with excellent conditions and high stability for product manufacturing, ultimately improving product performance and ensuring product yield.

It should be noted that the requirements for various contaminant indicators in cleanrooms are not fixed and unified but show significant differences: they are dynamically adjusted according to the downstream customer’s industry, the specific production link corresponding to the cleanroom, and the customer’s personalized needs. This determines that cleanrooms have a distinct high customization attribute.

Biosafety Level 3 cleanroom

From the perspective of the actual application needs of downstream industries, cleanroom engineering can usually be classified into two core categories: industrial cleanrooms and biological cleanrooms. There are clear differences between the two in terms of pollution control objects and application scenarios:

  • Industrial cleanrooms: Their core function is to control inanimate particles such as air dust. By restricting the intrusion and diffusion of these particles into the working environment, they provide clean protection for the production process. Their application scope covers industrial fields such as integrated circuit manufacturing, new display device production, and new energy battery R&D and production.
  • Biological cleanrooms: They focus on preventing living particles such as bacteria and microorganisms from polluting the working environment, thereby meeting hygiene and safety requirements in specific fields. Their main application scenarios focus on biopharmaceutical R&D and production, high-end medical device manufacturing, and animal laboratory construction and operation.

In the cleanroom engineering industry, the mainstream business models are divided into four types:

  1. Pure Construction Mode (referred to as “C Mode”);
  2. Engineering Design + Construction Integration Mode (referred to as “EC Mode”);
  3. Engineering Design + Procurement + Construction General Contracting Mode (referred to as “EPC Mode”);
  4. Engineering Design + Procurement + Construction + Operation & Maintenance Integration Mode (referred to as “EPCO Mode”).

Compared with the first three modes, the EPCO mode has significant advantages: it can effectively optimize the collaboration efficiency of all links in the whole project cycle, making the complete process of engineering design, equipment procurement, on-site construction, and later operation and maintenance more coherent in connection and consistent in execution, thus meeting customers’ needs in the whole project life cycle more accurately and comprehensively.

From the perspective of industry development trends, leading enterprises in the field are generally transforming towards the EPCO mode. By extending the service chain and improving the full-process capabilities, they continuously enhance their comprehensive service capabilities and market competitiveness.

Among the many indicators for evaluating the quality and level of cleanroom engineering, cleanliness is a particularly critical one. According to the relevant specifications of the internationally accepted standard ISO 14644-1, cleanliness is clearly divided into 9 different levels. However, the specific cleanliness requirements of different industries and production areas vary significantly:

  • From the industry dimension: The electronic information field (e.g., chip manufacturing, TFT-LCD display panels, HDD hard drives) has high cleanliness requirements, requiring strict control of air particle concentration to ensure precision production; while industries such as pharmaceutical manufacturing and food processing have relatively lower cleanliness requirements due to different production characteristics.
  • From the perspective of production area division: The use space of cleanrooms can be further divided into core areas and auxiliary areas. The core area is the most critical operation or production site in the cleanroom, directly related to the stability of the core production process of products, so it has the strictest requirements for air cleanliness level; in contrast, the auxiliary area mainly undertakes supporting functions, with looser requirements for cleanliness level.

5. Downstream Capacity Urgently Needs Expansion, and the Industry Has a Promising Future

5.1 Downstream Industries Benefit from Policies, Strengthening Demand for Cleanroom Engineering

The industrial chain structure of the cleanroom engineering industry is clear, mainly consisting of three core links:

  • Upstream: Material and equipment suppliers that provide basic support for engineering;
  • Midstream: Professional design and engineering implementation of cleanrooms;
  • Downstream: Various end-user enterprises that actually apply cleanrooms.

In terms of industry attributes, the cleanroom engineering industry belongs to the category of construction and installation engineering services. Its upstream supply chain covers multiple fields, including construction materials, hardware accessories, fire-fighting equipment, air conditioning systems, air purification and filtration equipment, mechanical and electrical equipment, lighting equipment, etc. The products provided by these fields are indispensable engineering materials and core equipment in the construction process of cleanroom engineering.

On the downstream application side, industries that rely on cleanroom environments during production or operation are widely distributed, covering the electronics industry, biopharmaceutical and medical health industry, food processing industry, precision instrument manufacturing, aerospace industry, and other fields. Different industries have differentiated requirements for the specifications and standards of cleanrooms according to their own production needs.

It is worth noting that the development of the cleanroom engineering industry has a strong correlation with the investment activities of downstream industries. As a core supporting facility for high-end manufacturing, cleanrooms are an essential link to ensure the production of high-end products—especially industries with extremely strict requirements for the production environment, such as IC semiconductors, new energy, and biopharmaceuticals. The rapid technological iteration and continuous capacity expansion of these industries will directly drive the construction and commissioning of new cleanroom workshops, as well as the upgrading and optimization of existing cleanroom supporting systems.

At present, downstream high-end manufacturing-related industries have been included in the national key encouraged strategic industry system, and the state has issued a large number of supportive industrial policies for these fields. While these policies inject development momentum into downstream industries such as semiconductors and new energy and promote the improvement of their scale and technological level, they will also bring synchronous development opportunities to the upstream cleanroom engineering industry through the transmission effect of the industrial chain, driving the cleanroom engineering industry towards higher quality and more refined development.

5.2 Chip Capacity Expansion and Technological Upgrading Ensure Demand for Cleanrooms

The R&D and production processes of the chip industry have extremely strict control standards for contaminants such as dust particles and metal ions in the air, and have particularly high requirements for the cleanliness of the production environment. As a key infrastructure that can accurately control pollutant concentrations and ensure the stability of various environmental indicators, cleanrooms have become an indispensable core component in the entire process of the chip industry from R&D to production. It can be seen that the expansion of the investment scale of the chip industry will directly drive the increase in demand for cleanrooms.

From the perspective of the global market pattern, the investment in the chip industry is currently continuing to rise, creating broad opportunities for the development of the cleanroom engineering industry. Specifically, in recent years, new-generation information technologies such as cloud computing, the Internet of Things, big data, and 5G have been accelerating their implementation and application. Coupled with the vigorous development of industries such as data center construction and autonomous driving technology commercialization, the demand for chips in the global high-end manufacturing industry chain has increased significantly. This demand gap has made global wafer manufacturers have a strong willingness to expand production, thereby attracting a large amount of investment funds to continue to flow into the chip industry.

According to data from the industry research institution IC Insights, the global chip industry investment reached USD 153.1 billion in 2021; the institution also predicts that the global chip industry investment will further increase to USD 185.5 billion in 2022, a year-on-year increase of 21% compared with 2021. This growth trend will continue to inject development momentum into the cleanroom engineering market.

Technological iteration in the chip industry is becoming an important factor driving the growth of demand in the cleanroom engineering industry. Driven by Moore’s Law, the chip industry has always been in a process of rapid technological change and upgrading. For chip manufacturers, the advanced level of manufacturing processes is the key to building core competitive barriers, directly related to the company’s market share and competitive position.

As of 2022, industry leaders have made significant progress in advanced process nodes: Samsung and TSMC have achieved mass production of 3nm chips, and Intel has also achieved the production capacity of 4nm chips; at the same time, major leading manufacturers have not stopped their pace of technological breakthroughs and are competing fiercely around the first implementation and deployment of 2nm advanced processes.

It is worth noting that technological innovation is not only reflected in the breakthrough of process nodes but also in the iteration of core device technologies. For example, Samsung Electronics clearly stated that its 3nm process does not adopt the mature FinFET (Fin Field-Effect Transistor) technology in the industry but instead uses the GAA (Gate-All-Around) transistor technology with better performance.

It is not difficult to see that with the continuous implementation and application of new processes and technologies in the chip manufacturing field, chip enterprises will inevitably need to systematically upgrade and transform existing production lines to adapt to new production requirements. As a core supporting facility for chip production, the specifications and standards of cleanrooms need to be upgraded synchronously to adapt to technological changes. This process will directly drive further growth in cleanroom construction demand.

5.3 PV Industry Based on New Power Systems Drives Increased Demand for Cleanrooms

The continuous development of the PV industry will provide an important driving force for the expansion of demand in the cleanroom engineering industry. In the product manufacturing link of the solar cell industry chain, the cleanliness of the production environment is one of the core requirements, and relevant processes have strict standards for clean conditions—for example, core manufacturing steps such as crystalline silicon preparation, battery silver paste production, and battery module assembly must be carried out in clean spaces that meet specifications.

This is because key parameters such as the concentration of contaminants and vibration amplitude in the environment directly affect the qualified rate and electrical performance of transistors during production, and also play a decisive role in the conversion efficiency of the final solar cell. Deviations in any environmental indicators may lead to a decline in product quality or performance.

From the perspective of future development trends, with the gradual popularization of photovoltaic power generation technology and the continuous expansion of application scenarios, the demand for large-scale construction of production lines in the PV industry will continue to be released. As an essential supporting facility for PV production, the demand for cleanrooms will also achieve significant and direct growth along with the construction boom of PV production lines.

modular cleanroom construction cost

Solar photovoltaics, with strong development momentum, is expected to break through the existing power structure and surpass coal to become the power source with the highest global share. The International Energy Agency (IEA) has made the judgment: although the rise in commodity prices will indirectly push up the investment cost of PV projects, photovoltaic power generation is still the lowest-cost option among newly added power generation projects in most countries around the world.

At the same time, the development potential of distributed solar photovoltaics will also be further released—driven by the dual factors of rising retail electricity prices and increasing policy support, distributed photovoltaics can not only conform to the trend of the energy market to achieve scale growth but also effectively help consumers reduce energy expenditure.

According to specific calculation data from the IEA, the cumulative installed capacity of global photovoltaic power generation accounted for 12.8% of the total power source structure in 2022; from the perspective of future trends, its proportion will gradually achieve a phased surpass: it is expected to exceed hydropower in 2024, surpass natural gas in 2026, and break through the proportion advantage of coal by 2027, officially becoming the world’s largest power source. At that time, its proportion in the total power source structure will increase to 22.2%.

6. The Competitive Landscape of High-End Cleanroom Engineering Is Better, with Distinct Advantages for Leading Enterprises

The market competition of the cleanroom engineering industry shows significant hierarchical characteristics: the competition in the low-end market is particularly fierce, while the mid-to-high-end market has a more favorable competitive landscape, with obvious differences between the two.

In the low-end market, there are a large number of enterprises participating in the competition, and most of them are small in scale. These enterprises mainly focus on scenarios with low cleanliness requirements—such as the manufacturing of ordinary electronic components, petrochemical processing, printing and packaging industries. Due to the low technical threshold in this field and the relatively basic supporting equipment and materials required, a large number of small and medium-sized enterprises have poured in, leading to fierce market competition.

In contrast, the mid-to-high-end market has significantly fewer enterprises participating in the competition and has a higher market access threshold: enterprises need to have core technology R&D capabilities in specific fields. Whether it is the breakthrough of high-precision cleanliness control technology, the design of customized solutions adapting to complex processes, or the integration and application capabilities of high-end equipment, all are the keys to establishing a foothold in the mid-to-high-end market. This technical threshold has effectively screened participants, making the competition in the mid-to-high-end market more rational and orderly, with a healthier overall competitive landscape.

In the cleanroom engineering industry, leading enterprises hold high-quality customer resources relying on their core competitiveness and cover an extremely wide range of industries in their business. These industry-leading enterprises generally have a comprehensive business layout, and relying on their high-standard technical strength and rich project experience, they can not only accurately match the high-demand clean engineering needs but also have the ability to undertake orders from large international technology enterprises—their service scope fully covers multiple key fields such as IC semiconductors, optoelectronic display panels, medical health, biopharmaceuticals, food and beverages, new energy, and electronic components, realizing cross-industry business expansion.

In contrast, due to the limitation of their own scale, small and medium-sized enterprises have a business scope mostly confined to a single field. More importantly, some industries with high cleanliness requirements (such as IC semiconductors, high-end optoelectronics) have clear threshold requirements for enterprises’ engineering and technical level and project experience, which small and medium-sized enterprises are difficult to meet. Therefore, their businesses are mostly concentrated in fields with relatively low technical thresholds, such as electronic parts manufacturing, conventional pharmaceutical industry, and ordinary food industry, and it is difficult to achieve cross-field breakthroughs.

7. Share Industry Development Opportunities and Focus on the Growth Opportunities of Leading Enterprises

The future development prospect of the cleanroom engineering industry is highly certain, among which leading enterprises are more likely to grasp industry dividends and benefit significantly from them.

From the demand side, the core downstream application fields of the cleanroom industry—such as chip manufacturing, PV industry, and grand health (including biopharmaceuticals, high-end medical care, etc.)—are currently operating at a high prosperity level, and these industries generally have clear capacity expansion plans and demands. The continuous release of this downstream demand has laid a solid foundation for the future market scale growth of the cleanroom engineering industry and clearly defined the development space of the industry.

From the supply side, the current market stratification of the cleanroom industry is very significant: the high-end market has high technical thresholds, project experience thresholds, and qualification thresholds, so the number of enterprises participating in the competition is limited, and the competition intensity is far lower than that of the low-end market; in the long-term development, leading enterprises have built distinct and irreproducible competitive advantages in key dimensions such as core technical level, high-quality customer resource reserves, and complex project engineering experience. These advantages together form a strong barrier to potential new entrants, further consolidating the leading position of leading enterprises in the high-end market.

Comprehensively speaking, under the dual background that the industry as a whole is in a high-speed development channel and the competitive pattern of the high-end market is relatively clear and stable, leading enterprises with comprehensive competitive advantages will be more capable of undertaking high-value orders from downstream, seizing more market share, and thus achieving faster development in the wave of industry growth, becoming the main undertakers of industry development dividends.

8. Risk Tips

1、Risk of Lower-Than-Expected Capacity Expansion in Downstream Industries: The demand for the cleanroom industry is closely tied to the capacity expansion rhythm of downstream industries such as chips, PV, grand health, and food. The development growth rate of these downstream industries has a strong correlation with the macroeconomic cycle and is vulnerable to direct impact from economic fluctuations. If the macroeconomic environment weakens in the future, downstream industries may experience slower-than-expected capacity expansion due to factors such as shrinking market demand and insufficient investment confidence. This will directly lead to a reduction in new demand for cleanroom engineering, restricting the overall development of the industry.

2、Risk of Intensified Industry Competition: In recent years, various social capitals have continued to pour into the cleanroom field, driving the number of enterprises in the industry to increase year by year and the market competition situation to gradually escalate. For existing industry participants, if they cannot continuously consolidate their advantages in key dimensions such as core technology R&D, refined management efficiency, brand reputation building, and process innovation optimization, they will be unable to cope with the increasingly fierce market competition, which may lead to a decline in their industry status, loss of core customers, and ultimately adverse impacts on their operating performance.

3、Risk of Rising Labor Costs: The implementation of cleanroom engineering relies on a large number of professionally skilled project implementation and technical personnel (such as clean system installation and commissioning personnel), with high requirements for the professional quality of labor. As China’s “demographic dividend” gradually fades, the overall supply of the labor market tends to be tight, while the demand for professional labor in the cleanroom industry is still growing, further expanding the supply-demand gap. Under this trend, enterprises will face continuous pressure of rising labor costs, which may push up the overall operating costs of projects and squeeze the profit level and production and operation efficiency of companies in the industry.

4、Risk of Raw Material Price Fluctuations: Cleanroom engineering projects require the procurement of a large number of core raw materials such as cables, ceiling materials, various pipes, and steel plates during the construction process, and the cost of these materials accounts for a relatively high proportion of the total project cost. The market prices of the above raw materials are affected by multiple factors such as commodity market conditions, supply chain stability, and policy regulation, showing periodic or sudden fluctuations. If the overall price of raw materials enters an upward channel in the future, it will directly increase the procurement costs of enterprises in the industry. If the project pricing cannot be adjusted synchronously, it may lead to a narrowing of the profit margin of enterprises and reduce the overall profit level of the industry.
