Common Questions About
Photolithography Components Machining

We machine aluminum 6061, Invar 36, Super Invar, stainless 304 and 316L, and granite-interface compatible alloys for lithography applications.
We hold ±0.001" on general features and ±0.0002" on critical bearing rail, air bearing, and lens seat features. CMM on every order.
Most litho component prototypes ship in 7 to 14 business days depending on complexity. Rush available on simpler stages and mounts.
Yes. We machine Invar 36 reticle stages and reference frames to provide low thermal drift for critical overlay performance.
