Abstract:
A semiconductor device comprising:a semiconductor substrate including semiconductor elements; element electrodes arrange on a main surface of said semiconductor substrate and electrically connected with said semiconductor elements; a passivation film formed on the main surface of said semiconductor substrate, and having a first opening disposed on said element electrodes; an elastic material layer formed on the main surface of said semiconductor substrate from an insulating elastic material; an opening formed by partially removing said elastic material layer for exposing at least said element electrodes on said semiconductor substrate; a metal wiring layer continuously formed to stretch from said element electrodes over said elastic material layer; and external electrodes formed as a part of said metal wiring layer on said elastic material layer for electrical connection with external equipment, wherein an entire lateral surface of said opening of said elastic material is separated from said element electrodes, an edge of said first opening of said passivation film projects from an edge of said opening of said elastic material layer toward the center of said opening, said elastic material layer is formed parallel to two sides of said semiconductor substrate, and said opening is band-shaped and parallel to said two sides of said semiconductor substrate.
