Abstract
A II-VI group compound semiconductor device includes a semiconductor substrate, a Zn.sub.X Mg.sub.1-X S.sub.Y Se.sub.1-Y (0.ltoreq.X.ltoreq.1, 0.ltoreq.Y.ltoreq.1) semiconductor layer formed on the semiconductor substrate, and an electrode layer formed on the semiconductor layer, the electrode layer containing an additive element of Cd or Te and a metal which can form a eutectic alloy with the additive element, thus achieving an electrode layer having a small contact resistance, especially an electrode layer with an ohmic contact.
