Abstract
Provided is a semiconductor device including transistor regions and diode regions each extending from a given one edge of an active region to a different edge of the active region, a first-conductivity-type pad well region in contact with a gate runner region shaped like a rectangular ring and provided within the gate runner region, and first-conductivity-type collector regions provided in the transistor regions in a one-to-one correspondence and second-conductivity-type cathode regions provided in the diode regions in a one-to-one correspondence. Here, an edge of the pad well region at which the pad well region ends in an arranging direction extends in an extending direction, and the arranging direction is orthogonal to the extending direction in which the transistor regions and the diode regions extend, and any one or more of the collector regions are positioned below the edge of the pad well region.
