Filed: 2000-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device where thermal storage is little and stable operation is enabled. SOLUTION: A trench 62 of an IGBT of a central part in a semiconductor device 100 in which IGBT's are arranged in a form of matrix is formed shallower than trenches of the IGBT's in the peripheral part. Since the trench 62 in the IGBT of the central part is shallow, the amount of majority carriers accumulated in a part along a gate insulating film 64 of a second conductivity type low concentration drift region 54 is smaller than that accumulated in the IGBT's in the peripheral part, and the amount of minority carriers to a region in the central part from a collector electrode is reduced. Consequently, ON-state resistances of the IGBT's 40, 42, 44 in the central part are made higher than those of the IGBT's in the peripheral part.  As a result, current density in a region in the central part of a semiconductor device 100 is reduced as compared with a region in the peripheral part, the increase of temperature of the region in the central part is made little, and the thermal storage can be relieved.
