Lithography etching
WebIntroducing Optical Lithography Lithography creates a resist image on the wafer. The subsequent etching, lift off, or ion implantation process is masked by the resist image at the areas dictated by the lithography mask. Hence, the thin film material on the wafer is selectively removed, built up, or its characteristics are selectively altered. Web23 mrt. 2024 · Lithography processing. Lithography processing is a series of processing steps used to pattern masks and samples with photoresist prior to other processing steps (e.g. deposition, etching, doping). There are a variety of lithography processes that are available in the LNF. This page specifically talks about optical (UV) lithography.
