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. Web11 aug. 2024 · Lithography is used to pattern a sample before a process step that a user does not want to affect their whole sample, primarily deposition, or etching. Before etching lithography is used to create a protective layer of resist that will only leave material where there is resist (negative pattern).
