SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING THE SAME

A semiconductor substrate includes a plurality of emitter formation regions separated from each other in a Y direction between a pair of trenches, and a separation region located between the emitter formation regions. A p-type base region is formed in the semiconductor substrate of each of the emitt...

Zusammenfassung:	A semiconductor substrate includes a plurality of emitter formation regions separated from each other in a Y direction between a pair of trenches, and a separation region located between the emitter formation regions. A p-type base region is formed in the semiconductor substrate of each of the emitter formation regions and the separation region. An n-type impurity region is formed in the base region of each emitter formation region. The impurity region is also formed in the base region at a position in contact with the pair of trenches in the separation region.
