Abstract
A method for manufacturing a semiconductor device having a Schottky junction which comprises a process for burying first and second regions of a second conductivity type spaced from each other in a semiconductor body of a first conductivity type, a process for locally disposing a first interconnection layer made of a metal on a surface region of the semiconductor body facing the first region, a process for forming an insulating film on the surface of the first interconnection layer by subjecting the surface to anodic oxidation, a process for ion-implanting an impurity of the second conductivity type into the semiconductor body except a portion thereof under the first interconnection layer at such an energy level that the impurity may reach the first and second regions, a process for activating the ion-implanted layer by applying a laser beam thereto, and a process for forming a second interconnection layer connected with the activated layer by covering the whole surface of the semiconductor body with a metal and patterning the metal.
