摘要

Production of a semiconductor component comprises forming a first semiconductor layer (4) on a substrate (1); producing a second semiconductor layer on the first semiconductor layer; and removing the second semiconductor layer with predetermined pattern by laser abrasion until the first layer is exposed to form an electrode pattern. Preferred Features: The substrate is made of single crystalline silicon. The first semiconductor layer is produced by joining a porous layer (2) to the substrate. The first semiconductor layer is produced as a p-semiconductor layer and the second semiconductor layer as an n-semiconductor layer.
