Abstract
PURPOSE:To strengthen the close adhesion between an electrode coming into contact with an n-type semiconductor layer and an insulating film by a method wherein the electrode coming into contact with the n-type semiconductor layer is constituted by chromium and gold which have been formed in succession. CONSTITUTION:A semiconductor device is formed by the following two steps: an insulating film 15 which has been formed on an n-type semiconductor layer 14 and where an opening has been made; an electrode 1 which has been formed on the insulating film 15 and which comes into contact with the semiconductor layer 14 via the opening. During this process, the electrode 1 is constituted by chromium and gold which have been formed in succession. Then, the semiconductor layer 14 and the electrode 1 display the ohmic contact; the close adhesion between the electrode 1 and the insulating film 15 is enhanced. By this setup, the close adhesion between the electrode 1 coming into contact with the semiconductor layer 14 and the insulating film 15 is strengthened.
