Electronics & Semiconductor Manufacturing
ULPA filtration, molecular contamination control, and toxic gas scrubbing for wafer fabs, cleanrooms, and electronics assembly — from ISO Class 1 to general manufacturing environments.
Semiconductor fabs demand the cleanest air of any manufacturing environment on earth. ISO Class 1–5 cleanrooms require filtration down to 0.1 μm where a single stray particle can destroy a wafer in process. But particle control is only part of the challenge — you also need molecular contamination control to protect photoresist chemistry, toxic gas scrubbing for process exhaust, and acid fume extraction from wet bench stations.
The Southwest has become a major semiconductor corridor. Arizona’s Chandler–Tempe area alone hosts some of the largest wafer fabs in the western hemisphere, and new facilities are expanding across the region. Whether you’re building a new fab, retrofitting an existing cleanroom, or need filtration for electronics assembly and PCB fabrication, we engineer systems that protect both yields and workers.
The desert environment adds a unique challenge for semiconductor facilities. Ambient dust loading is significantly higher than coastal or temperate regions, which puts more stress on pre-filtration stages and make-up air handling. Our designs account for this additional load so your cleanroom classifications are maintained year-round — including during monsoon season and haboob events.
Every system we install is backed by our pass-or-free compliance guarantee. If it doesn’t meet the specified cleanroom classification or pass inspection due to our design or installation, we fix it at no cost.
Semiconductor Fab Air Quality Challenges
ISO Class 1–5 Particle Control
ULPA filtration at 99.9995% efficiency down to 0.1 μm for critical process zones. Sub-micron particle counts must remain within classification limits 24/7.
Airborne Molecular Contamination
AMC control using activated carbon and chemisorbent media to protect photoresist chemistry, catalysts, and sensitive process materials from molecular-level contaminants.
Toxic Process Gas Exhaust
Arsine, phosphine, silane, and other hazardous gases used in deposition and doping must be scrubbed to safe levels before exhaust — both for worker safety and EPA compliance.
Wet Bench Acid & Solvent Fumes
High-velocity capture hoods for HF, sulfuric, nitric, and solvent cleaning stations. Fume extraction must prevent cross-contamination between process baths.
Laminar Flow Integrity
Unidirectional airflow in critical tool bays with zero turbulence. Fan filter unit (FFU) arrays must deliver uniform velocity across the entire ceiling with minimal pressure variation.
Energy Efficiency at Scale
Fabs process massive air volumes — low-pressure-drop filters, EC motor FFUs, and smart controls are essential to managing energy costs without compromising cleanliness.
What We Design & Install
ULPA Fan Filter Units (FFUs)
99.9995% efficiency at 0.1 μm for ISO Class 1–5 environments. Ceiling-mount arrays with EC motors, low pressure drop, and uniform velocity distribution. Quick-ship standard sizes available.
Chemical Scrubbers
Wet and dry scrubbing systems for toxic gas neutralization — arsine, phosphine, silane, chlorine, and other process gases. Sized for single-tool or multi-tool exhaust headers.
Molecular Filtration (AMC)
Activated carbon, chemisorbent, and hybrid media for airborne molecular contamination control. Protects photoresist, thin film, and deposition processes from organic and inorganic vapors.
Wet Bench Exhaust Systems
High-velocity capture hoods with acid-resistant ductwork for HF, sulfuric, nitric, and solvent stations. Ductless options available where exhaust routing is impractical.
ESD-Safe Dust Collection
Grounded, static-dissipative systems for PCB fabrication, component assembly, and test operations. Prevents electrostatic discharge damage to sensitive devices.
HEPA & ULPA Pre-Filtration
Make-up air pre-filtration stages designed for the Southwest’s heavy ambient dust loading. Protects final ULPA filters from premature loading and extends service life.
Common Semiconductor & Electronics Applications
