Wafer handling. Vacuum chambers. ASML Tier-2.

Semiconductor parts must be extremely clean — particles, ionic contamination, outgassing all critical. Our semiconductor workflow: dedicated machining area (no cross-contamination), ultrasonic clean in multiple stages (DI water + IPA + specialty solutions), packaging in class 1000 / ISO 6 clean environment, double-bagged delivery. For critical semiconductor parts, individual particle counts documented.

Semiconductor handling requires ESD-safe materials — prevent static damage to sensitive semiconductor devices. Common ESD-safe materials: PEEK-CF30 (carbon-filled PEEK, surface resistance 10^4-10^6 Ω), conductive Delrin, specific ESD-safe machined plastics. We machine ESD-safe materials in dedicated ESD-safe area with documented material certification.

Semiconductor vacuum chambers require ultra-low outgassing components — trapped gases release slowly, contaminating processes. Critical for processes targeting atomic-layer purity. Materials: 316L electropolished, Vespel SP-1, OFE copper, specific UHV-qualified ceramics. Processing: thorough cleaning, vacuum bake-out at elevated temperature to drive off residuals. Our semiconductor parts meet sub-10^-10 mbar·L/s total outgassing.

Semiconductor equipment pushes precision limits. Typical: lithography stage features ±0.005 mm. Optical mount datums ±0.002 mm. Standard industrial: ±0.01-0.025 mm. We CMM-verify critical dimensions with temperature-compensated measurements. For sub-micron critical features, interferometric measurement through partner labs.

Common semiconductor-industry materials: 316L (chamber structural), Invar 36 (precision stages, low thermal drift), Mo-Cu composite (thermal management with CTE matching silicon), PEEK-CF30 (ESD-safe wafer handling), aluminum 6061 (general), specialty ceramics (aluminum oxide, silicon carbide — through partners). Material choice driven by specific application — chemistry, temperature, vacuum, cleanliness requirements.

Semiconductor programs typically plan 12-24 weeks ahead. Material sourcing for specialty alloys: 4-6 weeks. Machining: 4-8 weeks for complex work. Qualification testing and documentation: 2-6 weeks. Production programs: ongoing monthly deliveries with standing PO. For production equipment manufacturers (ASML, AMAT), supplier relationships are years-long with regular orders.
