Abstract

The present invention provides a device having a useful structure which is arranged on a substrate and has a useful structure side edge. In addition, an auxiliary structure is arranged on the substrate adjacent to the useful structure, the auxiliary structure having an auxiliary structure side edge, wherein the useful structure side edge is opposite to the auxiliary structure side edge separated by a distance, and wherein the auxiliary structure useful structure distance is dimensioned such that a form of the useful structure side edge or a form of the substrate next to the useful structure side edge differs from a form in a device where there is no auxiliary structure.
