Abstract:
1. A semiconductor device, comprising: a substrate, including an electrode pad; a semiconductor element, mounted on the substrate; and one or more externally connecting terminals, formed on the electrode pad and electrically connected with the semiconductor element, each of said one or more externally connecting terminals including a core made of an elastic material and including a metal layer formed outside the core, wherein the electrode pad on which said one or more externally connecting terminals are formed is formed so as to be closer to a surface of the substrate on which surface the semiconductor element is mounted than to a surface of the substrate which surface is opposite to the surface on which the semiconductor element is mounted, and wherein the electrode pad on which said one or more externally connecting terminals are formed is formed in a concave section or a step section formed on the surface of the substrate which surface is opposite to the surface on which the semiconductor element is mounted.
