Semiconductor
& Electronics Manufacturing
Ultra-clean sintered metal filter elements for process gas delivery, chemical mechanical polishing slurry, and cleanroom environment control — where a single metal particle above the critical dimension kills a chip yield target.
Ultra-High-Purity Sintered Metal Filtration for Semiconductor and Electronics Manufacturing
As semiconductor feature sizes shrink, the tolerance for particulate contamination also narrows. In process gas and DI water service, filter elements are selected for stable pore structure, clean surfaces, and low risk of media migration during operation.
Sintered stainless steel filter elements address the particle cleanliness requirement. The sintered metal matrix is mechanically stable — no fibers, no binders, no migration risk. The solid sintered structure minimises surface area for particle adhesion compared with woven or fibrous media.
FILTURE supplies SS 316L sintered filter elements for semiconductor process gas delivery, chemical distribution, and CMP slurry filtration. For DI water polishing loops and gas diffusion applications, our sintered porous discs and tubes provide controlled distribution. Clean packaging and particle count testing are available on request for critical applications.
Housing dimensions are held to tight tolerances through post-sinter precision machining, and every batch can ship with particle count and material test reports for fab qualification records.
Filtration Points Across the Semiconductor Process
Process Gas Delivery Filtration
Sintered SS inline filters on N₂, Ar, H₂, and specialty gas distribution lines — a tightly-controlled pore size barrier limiting particles reaching process chambers, deposition tools, and etch systems.
0.5–5 µm · Low migration riskCMP Slurry Point-of-Use Filter
Point-of-use filtration on chemical mechanical polishing slurry distribution — removing oversized abrasive particles before they reach the polishing pad and cause micro-scratch defects on wafer surfaces.
0.5–2 µm · Abrasion-resistant SSWet Chemical Distribution
Filtration for selected wet-process chemical delivery systems. Material selection must be reviewed against the actual chemical, concentration, temperature, pressure, wetted construction and cleaning method; HF or fluoride-bearing media are not default 316L or titanium applications.
1–5 µm · Compatibility review requiredCleanroom HVAC Pre-filtration
Metal pre-filters on cleanroom HVAC and make-up air systems — protecting HEPA and ULPA filter banks from coarse particulate loading, extending final-filter service intervals.
5–50 µm · Stainless steel · Long lifeDI Water Final Filtration
Sintered SS elements as point-of-use filters on deionised water distribution loops — removing particles and bio-burden before water contacts wafer surfaces in cleaning and rinsing operations.
0.22–1 µm · DI-compatibleDiffusion Furnace Atmosphere Control
Gas inlet sintered filters on diffusion and oxidation furnaces — maintaining ultra-pure N₂ and O₂ atmosphere in tube furnaces where any metallic contamination causes device leakage.
0.5–2 µm · High-purity · No outgassingUltra-High-Purity Sintered Metal Filters for Semiconductor Cleanroom Environments
Controlled packaging options and particle count test reports are available on request for critical semiconductor applications.

View DetailsWhat Semiconductor Process Engineers Demand
Low Media Migration Risk
Sintered SS is a solid, rigid structure with no loose fiber layers or binder resin in the filtration body. Compared with woven or polymer-based media, the sintered matrix is often selected where low particle release risk is important.
All-Metal Filter Structure
Sintered stainless steel is a mechanically bonded metal matrix without a loose fibre layer or binder resin in the filtration body. Particle cleanliness must still be verified against the specified product, cleaning process, operating conditions and agreed test method.
Surface-Uniformity Documentation
For porous gas-distribution plates, Bubble Distribution analysis can document bubble uniformity across the effective surface together with requested test-condition pressure-drop records. Dimensional records and material certifications are available for traceability.
