Alfred wong offers rigorous underpinning, clarity in systematic formulation. The mask can be placed far away from the wafer projection printing used in stepping and scanning systems. A comparison of the optical projection lithography simulators in sample and prolith semiconductor manufacturing, ieee transactions on. Prolith is designed to be a versatile, comprehensive submicron optical lithography model. Dn hydrogels were printed by first photocrosslinking a single network structure via spatially modulated light. Photolithography is a patterning process in which a photosensitive polymer is selectively exposed to light through a mask, leaving a latent image in the polymer that can then be selectively dissolved to provide patterned access to an underlying substrate.
