Abstract:
1. A method of fabricating a two-terminal semiconductor component using a trench technique, comprising: forming a trench by etching an etching pattern formed on a substrate on which an active layer having impurities added is grown; forming a front metal layer on a front upper surface of the substrate by using an evaporation method or a sputtering method after removing the etching pattern; forming a metal plated layer on the front surface of the substrate on which the front metal layer is formed, the metal plated layer being thicker than a side of the trench; polishing a lower surface of the substrate by using at least one of a mechanical polishing method and a chemical polishing method until the front metal layer is exposed; forming a rear metal layer on the polished substrate, the rear metal layer being for forming a metal electrode; and removing each component by using at least one of a dry etching method and a wet etching method.
