China to focus more on Optical lens, for Microlithgraphy.That's the system that transfer design mask to photoresist on wafer. Optics system requires exceptional optical lens. International maker such as Nikon and Carl Zeiss supply those lens to semiconductor maker microlithography equipment such as Tokyo electron and ASML.
Critical for China to develope otpical lens for Microlithography,
Nikon’s first wafer stepper “NSR-1010G” was developed
with a g-line projection lens in 1980.
look how big those lens of the NSG-1010G.
