Built for the Equipment Makers Behind Every Wafer in Silicon Valley
San Jose runs the machines that make semiconductors possible. Applied Materials, Lam Research, and KLA — the three largest semiconductor equipment companies on earth — all have engineering and manufacturing teams here. Their suppliers and sub-tier vendors fill the surrounding industrial parks off North First Street and along the Guadalupe corridor.
RivCut machines the precision components that go inside that equipment. Chamber bodies, wafer end-effectors, electrostatic chuck bases, and gas distribution plates — all held to tolerances your process engineers demand. We ship from Union City, 30 miles north, same day when you need it.

Precision CNC Machining for Semiconductor Equipment Teams
Semiconductor equipment companies in San Jose need parts that are ultra-precise, contamination-free, and fully documented. A wafer end-effector that's off by 0.001 inches can cause misalignment across thousands of wafers. We machine aluminum, stainless, and UHV-compatible materials to tolerances as tight as ±0.0001 inches.
UHV-Compatible Materials
We machine aluminum 6061/7075, 316L stainless, and UHV-compatible alloys — all cleaned and packaged to semiconductor standards.
Ultra-Tight Tolerances
We hold ±0.0005" on standard features and ±0.0001" on critical wafer-handling surfaces. Every part is CMM verified with documented results.
Contamination-Free Delivery
Parts ship in cleanroom-compatible packaging with cleaning documentation. Your receiving team knows what they're getting before the bag is opened.
What We Machine for San Jose Semiconductor Teams
San Jose semiconductor programs demand precision, traceability, and speed. We deliver all three with every order.
Wafer Handling Components
End-effectors, paddle arms, and blade assemblies need flat, burr-free surfaces so wafers seat without micro-scratches. We machine these from 6061-T6 and 7075-T73 aluminum to flatness within 0.0002 inches. Every edge is hand-deburred and inspected before leaving the shop.
Sub-micron flatnessProcess Chamber Parts
CVD and etch chamber components see corrosive chemistries and high vacuum. We machine 316L stainless, Hastelloy C-276, and hard-anodize-ready aluminum to your stack-up drawings. Internal bores and gas port passages are machined to ±0.0005 inches with full CMM documentation.
Vacuum-tight sealsGas Delivery System Parts
Chuck bases require parallel surfaces, precise bolt patterns, and internal coolant channels that cannot leak. We machine these in one setup when geometry allows, reducing stack-up error across the assembly.
ElectropolishedVacuum System Components
Hundreds of small-diameter holes at exact spacing — this is standard work for us. We drill arrays as tight as 0.030-inch diameter through aluminum and ceramic-coat-ready substrates, checking every hole pitch on CMM against your DXF.
Leak-tightMetrology & Test Fixtures
Assembly fixtures used on your production floor need to be as accurate as the parts they hold. We build these from tool-steel and hardened aluminum so they stay in tolerance across thousands of cycles.
Ultra-preciseSemiconductor R&D Prototypes
Rapid prototypes for fab equipment and process development. 1 to 50 pieces with full material certs and surface finish verification.

NASA Ames Research Center in nearby Mountain View adds another axis to the local ecosystem. Ames runs semiconductor-adjacent programs in thin-film sensors and MEMS devices that share the same precision machining supply chain.
Applied Materials — CVD, PVD & Etch
The world's largest semiconductor equipment company. Applied Materials' tools are in virtually every fab globally, creating a massive supply chain demand for precision-machined chamber components.
Lam Research — Etch & Deposition
Lam's VECTOR and Kiyo systems require tight-tolerance machined parts from qualified suppliers. A key anchor of semiconductor equipment supply chains.
KLA Corporation — Process Control
KLA's inspection and metrology tools require ultra-precise machined components. Their tools ensure chips are built right — from wafer in to die out.
ASML, Tokyo Electron & Others
Lithography and process equipment OEMs rely on precision machining suppliers for chamber components, stages, and structural assemblies.
Why San Jose Equipment Teams Use RivCut
Your engineering team is in San Jose. RivCut is in Union City — 30 miles up I-880. That matters when a program review surfaces a dimension error on a Friday afternoon and you need a corrected part Monday morning for your ATE bring-up.
Ultra-Precision Tolerances
We are on Pacific Time. When your mechanical engineer calls at 4 p.m. to talk through a revision, someone picks up. No three-hour lag, no email chain that resolves the next business day in a different time zone.
Cleanroom-Compatible Packaging
Our lead times for prototype semiconductor components run three to seven business days from approved drawings. For in-process emergencies — tooling that breaks during a scheduled qual run, for example — we have accepted same-day starts on parts where stock material is on hand.
CMM Inspection Every Order
We understand the documentation chain semiconductor equipment companies carry. First Article Inspection reports, material certifications, and CMM reports travel with every order. If your supplier qualification process requires a facility visit, Union City is a 35-minute drive from North First Street. Engineers from Lam Research, Applied Materials, and their supply base have visited our shop floor. We are comfortable with that process.
Fast Prototype Turnaround
We also package to semiconductor standards. Parts ship in sealed poly bags with foam-lined boxes or clamshell trays. Cleanroom wipe-down before bagging is available on request. Nothing arrives with machine oil on a wafer-contact surface.
