Precision CNC Machining for Renton Semiconductor Equipment OEMs
Semiconductor equipment companies need machining partners who understand ultra-clean aluminum machining, critical flatness on wafer paddle faces, and tight bore tolerances for chamber sealing interfaces. A wafer handling end-effector with a non-flat paddle face will introduce tilt error that shows up as edge non-uniformity in CVD and etch processes. A chamber liner with a out-of-spec OD fit allows gas bypass around the liner, contaminating the chamber with non-process gas species. RivCut machines semiconductor equipment components to ±0.001" bore tolerances, flatness ≤0.001" on wafer paddle faces, and ±0.002" hole-pattern true position on gas distribution plates — with ultra-clean tooling and SEMI-compatible packaging.
Ultra-Clean 6061-T6 Machining
Semiconductor-grade 6061-T6 machined with dedicated clean tooling, minimal cutting fluid, and dry finishing passes. No cross-contamination with ferrous alloys. All semiconductor parts are packaged in double anti-static poly with desiccant for particle-count maintenance during shipping to Renton-area fab equipment OEMs.
Flatness-Critical Wafer Hardware
Flatness ≤0.001" on wafer handling paddle faces and electrode plate seating surfaces. Stress relief before final finish passes to eliminate aluminum springback. CMM verification of flatness on every critical semiconductor surface — because wafer tilt compounds into yield loss at the process level.
Chamber and Gas System Tolerances
±0.001" OD on chamber liner fits for gas-tight sealing in CVD, PVD, and etch tools. ±0.002" true position on gas distribution hole patterns across electrode and showerhead plates. Hard anodize Type III per MIL-A-8625 on plasma-facing chamber surfaces for etch-resistant oxide layer.
