Lithography and its types
Web3 mei 2024 · Lithography, which is also called optical lithography or UV lithography, is a process used in microfabrication to pattern parts of a thin film or the bulk of a substrate. It uses light to transfer a geometric pattern from a photomask to a light-sensitive chemical "photoresist", or simply "resist," on the substrate. Web• Types: – photographic emulsion on soda lime glass (cheapest) – Fe 2 O 3 on soda lime glass – Cr on soda lime glass – Cr on quartz glass (most expensive, needed for deep UV litho) • Dimensions: – 4” x 4” x 0.060” for 3-inch wafers – 5” x 5” x 0.060” for 4-inch wafers • …
