Lithography types
Web2 dec. 2024 · Semiconductor lithography equipment is used to perform exposure, part of the semiconductor chip manufacturing process. Semiconductor chips are created by performing exposure of microscopic circuit patterns on semiconductor substrates called "wafers." Semiconductor lithography equipment exposes wafers by using projection … Webmophores or add photosensitizers, and neither type of procedure is convenient. We have developed an alternative, non-photolithographic set of microfabri-cation methods that we call soft lithography (18–20) because all its members share the common feature of using a patterned elastomer as the stamp, mold, or
