Technical Examples

To produce a mask, a first mask layer (40) is applied to the substrate (10). During or after the deposition of the first mask layer (40), the latter is exposed to an etching step. The etching step is carried out in such a manner that the material of the first mask layer (40) that has been deposited on side flanks (30) of the raised structure (20) is completely removed from the side flanks (30) or is at least in sections completely removed from the side flanks (30). A second mask layer (50) is applied to the first mask layer and to the uncovered side flank sections (150) of the raised structure (20). Then, the first and second mask layers can be patterned so as to complete the mask (60).
