Abstract:
A method of patterning a substrate comprising:forming an electrically conductive etch mask layer over a substrate;forming and patterning a resist layer over the etch mask layer;etching into the etch mask layer through an opening formed in the patterned resist;removing the etch mask layer and resist from the substrate; andthe electrically conductive etch mask layer comprising an organic polymer selected from the group consisting of polypyrrole, polyacetylene, polyphenylene, polyphenylenevinylene, polythiophene, copolymers of N-substituted pyrroles and thiophene, polyquinolines, polycarbazoles, polyphenothiozones, polyphthalocyanines, polyphenylsulfide, and mixtures thereof.
