Abstract

A method for applying a predetermined structure of a structural material to a semiconductor element. The method includes the following steps: A) partially covering a surface of the semiconductor element with a masking layer, B) applying a film of a structural material to the masking layer and to the surface of the semiconductor element in the zones that are devoid of the masking layer and C) removing the masking layer together with the structural material present on the masking layer. The method according to the invention provides that between process steps B and C, the film of structural material is partially removed in a process step B2.
