Abstract

PURPOSE: To obtain elements comforming to mask shape by providing an electrode layer layer having a solder layer on the surface on both sides or the entire surface of one side of a semiconductor substrate, holding one side fixed, affixing a mask material on the solder layer on the surface of the other side, selectively etching away the solder layer thereafter cutting the substrate through spraying of sand.
