SEMICONDUCTOR DEVICE AND ELECTRIC POWER CONVERSION SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor device capable of preventing heating concentration breakdown due to heat evolution in a sense emitter connection part and an electric power conversion system using the same.SOLUTION: A semiconductor device comprises: a first electrode layer formed on one principal surface of a semiconductor substrate; and a second electrode layer formed on the other principal surface of the semiconductor substrate. The semiconductor device is constructed so as to take an electrical conduction to an external part by contacting the first electrode layer and second electrode layer in a vertical direction to the layer with a pressure, and can be actively switched the electrical conduction by an external signal. The semiconductor device further comprises: a first region to be press-fitted in a region of the first electrode layer; and a second region for taking out a sense potential in a part outside the first region to be press-fitted. The second region serves as a conduction suppression part in a conductive state.SELECTED DRAWING: Figure 1
