Abstract:
A semiconductor device comprising:a semiconductor substrate including semiconductor elements;element electrodes arranged on a main surface of said semiconductor substrate and electrically connected with said semiconductor elements;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;external electrodes formed as a part of said metal wiring layer on said elastic material layer for electrical connection with external equipment;a protecting film formed to cover said metal wiring layer and having a property to repel a conductive material;openings each formed through said protecting film for exposing at least a part of each of said external electrodes of said metal wiring layer;an external electrode terminal formed at least on a part of each of said external electrodes exposed in said openings of said protecting film,wherein said elastic material layer has a wedged section inclined to the surface of said semiconductor substrate in an end portion thereof in the vicinity of said opening, andsaid protecting film has an inclination of generally constant thickness along the end portion of said elastic material layer, in the region on top of the end portion thereof in the vicinity of said opening.
