Confirmation that CAS Ningbo replaced linear/voice coil motors in Nikon stepper wafer/reticle stage with their own design. Both the interferometer and the motors of the wafer stage in Nikon got modified and replaced with domestic parts
When I see stuff like this, just makes me wonder if stuff completely gets cut off, what spare parts can't be replaced without their help. Not the same industry but China did keep S-70 operational long after America stopped supporting them.
