Semi-Conductor Filtration Engineering
In front-end semiconductor fabrication, wafer surface defects as small as 10 nanometers result in fatal microchip failure. Trinity delivers advanced chemical mechanical planarization (CMP) slurry filters that remove killer agglomerates while preserving active working abrasive particles, alongside all-fluoropolymer PTFE/PFA filters engineered for aggressive wafer cleaning chemistries (Piranha, SC-1, SC-2, and HF etchants).
Critical Separation Challenges
Key operational bottlenecks, contamination hazards, and compliance challenges in Semi-Conductor.
CMP Slurry Micro-Scratching on Silicon Wafers
Oversized agglomerated abrasive particles (> 1.0 µm) scratch wafer oxide and copper layers during planarization, destroying dies.
High-Temperature Piranha & SC-1 Wet Chemical Etch
Piranha solutions (H2SO4 + H2O2 at 130°C) melt ordinary polypropylene, shedding carbon particulates onto freshly etched wafers.
Micro-Bubbles in Photolithography Photoresist
Dissolved gas micro-bubbles trapped in high-viscosity photoresist create pinholes during spin coating, distorting circuit patterns.
Sub-Micron Airborne & Gas Impurities
Trace hydrocarbons and particles in CDA (Clean Dry Air) and process gases cause gate oxide degradation and yield loss.
Process Flow & Engineered Solutions
Engineered multi-stage filtration loops and precision separation media designed for maximum process yield in Semi-Conductor.
CMP Slurry Distribution Loop
Depth-gradient polypropylene cartridges remove oversized agglomerates (> 1 µm) without stripping working abrasive nanoparticles.
Hot Piranha & SC-1 Chemical Etch
All-fluoropolymer PTFE membrane elements and PFA housings withstand aggressive boiling oxidizers up to 180°C.
Photoresist Spin Coater POU
Disposable STERI-PRO CP capsules dispense bubble-free photoresists with zero fluid dead volume.
High-Purity Process Gas Filtration
Hydrophobic PTFE membrane gas filters achieve 0.01 µm absolute retention in CDA, N2, and argon lines.
