Claim:
1. An Insulated Gate Bipolar Transistor (IGBT) comprising: a semiconductor substrate having a main surface; and elements having a plurality of insulated gate transistor parts arranged in a row in one direction over the main surface; the elements including a first element located at an end of the row in the one direction; and a second element located more centrally in the row in the one direction than the first element; wherein the first element includes a first insulated gate transistor part, and the second element includes a second insulated gate transistor part and a third insulated gate transistor part that are arranged symmetrically to each other in the one direction, and wherein current capability of the first element located at the end is higher than current capability of the second element located centrally, wherein the first insulated gate transistor part includes a first gate electrode formed over a portion of a first base region at a first side of the first base region and a portion of a first element separation structure formed in the main surface, the first base region being formed in the main surface; wherein the second insulated gate transistor part and the third insulated gate transistor part include a second gate electrode and a third gate electrode, respectively, which are formed over a second base region formed in the main surface, the second base region being common to the second gate electrode and the third gate electrode, wherein in the one direction, a distance between the second gate electrode and the third gate electrode is more than twice as long as a distance between the first gate electrode and a second element separation structure formed on a second side of the first base region that is opposite to the first side of the first base region, and wherein a channel length of the second element located centrally is same as a channel length of the first element located at the end.
