Semiconductor device and method for manufacturing the same

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;
• 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 end portion of said opening of said elastic material layer is separated from said element electrodes.
