Semiconductor Cleanroom Solutions
Biogreen provides process-specific cleanroom engineering for semiconductor and microelectronics manufacturing. We design and validate controlled environments that minimize particle, chemical, AMC, ESD and environmental risks to protect yield, reliability and device performance.
Semiconductor Cleanroom Design Starts With the Process
Every semiconductor process has different contamination, chemical, ESD, temperature and humidity requirements. Our engineering team starts with your process flow, materials and equipment to define the right cleanroom classification, airflow, filtration, environmental controls and exhaust strategy.
We do not design based on a universal ISO class. We design cleanrooms that meet the actual needs of your semiconductor process.
Semiconductor Cleanrooms Must Control More Than Particles
Particle Control
Control particle concentration, airflow pattern and filtration efficiency to protect critical dimensions, film deposition, lithography, etch and packaging from yield loss and defects.
Airborne Chemical Contamination
Control acidic, basic and organic molecular contaminants (AMC) from people, materials, processes and equipment outgassing.
ESD Control
Control electrostatic discharge to protect ESD-sensitive devices, wafers and components, including materials, grounding, wrist straps and ionization where required.
Temperature & Humidity Control
Maintain stable temperature and humidity to support process window, equipment stability and device reliability across wafer fab, assembly and test operations.
Define Cleanliness by Process — Not by a Universal Semiconductor ISO Class
Different semiconductor processes require different particle limits. We help you define the right cleanliness target based on your actual critical process steps.
- Use ISO 14644 as a reference framework, not as a one-size-fits-all target across the entire fab.
- Define ISO class, differential pressure, air changes and monitoring based on sensitivity of each process area.
- Align cleanliness targets with yield, reliability and cost of ownership.
Airflow, HEPA / ULPA and FFU Integration
- Design airflow patterns that support unidirectional or non-unidirectional requirements for each process area.
- Select HEPA / ULPA filters, FFUs, plenums and ductwork based on required cleanliness, airflow and energy efficiency.
- Balance air changes, pressure cascade and turbulence to minimize particle intrusion and cross-contamination.
- Integrate real-time monitoring of particle, airflow, pressure and filter performance.
AMC, Chemical Filtration and Process Exhaust
- Identify process-specific chemical contaminants and AMC sources.
- Select appropriate filtration media, gas-phase filters and scrubbers for each chemical.
- Design process exhaust systems with proper capture, ductwork, filtration and safe discharge.
- Maintain negative pressure in process tools and chemical areas to protect people, product and the facility.
ESD and Environmental Stability Built Into the Cleanroom
- Use ESD-safe flooring, furniture, garments, tools and materials for ESD-sensitive areas.
- Provide grounding, bonding and ionization where required to control electrostatic charge.
- Maintain stable temperature and humidity with precision HVAC systems.
- Monitor and alarm temperature, humidity, differential pressure, particle and AMC levels.
Integrating Cleanroom Infrastructure With Semiconductor Equipment
- Coordinate layout, utilities, exhaust, DI water, CDA, vacuum, power and data with tool requirements.
- Design vibration control, floor loading, access and maintenance for critical equipment.
- Ensure cleanroom systems support tool uptime, process window and long-term reliability.
Cleanroom Performance Verification for Semiconductor Processes
- Perform IQ / OQ / PQ for cleanroom, HVAC, filtration, monitoring and alarms.
- Verify particle counts, airflow, pressure cascade, temperature, humidity and AMC levels.
- Provide documentation to support process validation, audits and customer requirements.

Semiconductor Cleanroom FAQs
We review the process steps, contamination sensitivity, equipment layout and operating condition before defining the required cleanliness level for each area.
Yes, where AMC is identified as a process risk. The solution can coordinate materials, molecular filtration, fresh-air treatment, exhaust and monitoring as required.
ESD control is coordinated with the actual tool and process requirements and can include flooring, grounding, bonding, ionization, personnel controls and equipment interfaces.
Temperature and humidity targets are developed from process sensitivity, equipment heat load, ESD needs and required operating stability rather than one universal setpoint.
Yes. Engineering can be developed for new facilities, expansions, retrofits and process upgrades after reviewing the existing cleanroom and utility conditions.
Depending on scope, verification can include particle counts, airflow, pressure, temperature and humidity checks, HEPA/ULPA integrity testing and other project-specific measurements.
Yes. We coordinate cleanroom architecture with tool layout, power, DI water, CDA, vacuum, process gases, cooling, exhaust, access and maintenance requirements.
Typical applications include wafer fabrication, front-end and back-end processes, advanced packaging, testing, pilot lines, MEMS, power semiconductors and related microelectronics manufacturing.
