Litho etch
WebFor example the developed photoresist can act as an etching mask for the underlying layers. 1.1.2 Etching Etching is used to remove material selectively in order to create patterns. The pattern is defined by the etching mask, because the parts of the material, which should remain, are protected by the mask.
