Demcon focal has the capabilities to design, deliver and qualify one of the most demanding precision optical assemblies: the lithography lens. Demcon uses state-of-the-art alignment tooling (Opticentric) and cleanroom facilities to achieve diffraction limited imaging for a large field of view. We designed a lithography lens with high NA and large field of view that is capable of imaging semiconductor structures on wafers to produce processors, LEDs, MEMS, USB memory, etc.
