Abstract
An ohmic contact to II-VI compound semiconductor device for lowering the contact resistance and increasing the efficiency and reliability of a photoelectric device. The method of manufacturing the ohmic contact to a II-VI compound semiconductor device comprises the steps of forming a II-VI compound semiconductor layer on the substrate, forming a mask layer with a contact via on the II-VI compound semiconductor layer, forming a metal-contact layer on the mask layer and II-VI compound semiconductor layer, and removing the metal-contact layer over the mask layer, wherein the remainder of the metal-contact layer forms the ohmic contact. In order to prevent oxidization of the metal-contact layer, a shield layer comprised of a noble metal can be disposed on the metal-contact layer.
