Abstract

PURPOSE:To reduce a series resistance of a semiconductor device, and to enable the device to be produced at a low cost, by forming a concave section in one principal plane of the device, and forming a metal layer over approximately the full surface of the principal plane including the concave section, thereby the internal layer of the concave section being made a thin film. CONSTITUTION:A concave section 6 is formed in one principal plane of a semiconductor device, and a metal layer 7, 7' is formed over approximately the full surface of the principal plane including the concave section 6, thereby the internal layer of the concave section 6 is made a thin film. For example, an epitaxial layer 2 is grown on a crystalline silicon substrate 1 containing n type impurity of high concentration, and a p type impurity diffusion layer 4 is formed on the surface of the layer 2. Next, after a silicon oxide film 3 is selectively formed on the layer 4, the rear of the substrate 1 is partially etched away to form the concave section 6. Moreover, a rear metal layer 7, 7' and a surface electrode layer 5 are formed to produce a diode.
