Method and Device for Structuring a Substrate
First Claim
1. A method for structuring a substrate, according to which at least one mask with an opening is positioned above the substrate and unmasked regions are changed compared to masked regions of the substrate to form structures, a reproduction of the mask opening being produced on and/or in the substrate during the structuring process, which reproduction is smaller than the mask opening wherein the surface(s) of the mask opening(s) is (are) verified by appropriate means.

Abstract
The invention relates to a method for structuring a substrate. According to said method, at least one mask with at least one opening is arranged over the substrate, and unmasked regions are modified in relation to masked regions of the substrate in order to form structures. The inventive method is characterised in that the representation of the mask opening on and/or in the substrate has smaller dimensions than those of the actual mask opening. The invention also relates to a device for carrying out said method.
