Claim Text:
1. A semiconductor device in one package comprising: a first switching device; a second switching device, the first switching device and the second switching device being connected in series between a voltage input terminal and a reference voltage terminal; and a driving circuit that complementarily drives the first switching device and the second switching device, wherein the second switching device is composed of a semiconductor substrate including: wherein the current detecting region has a third conductor and a fourth conductor disposed on a main surface of the current detecting region, the third conductor being in direct contact with the second semiconductor region and the third semiconductor region, and the fourth conductor being in direct contact with the second conductor; wherein the second switching device further includes at least four pads including a gate pad, a source pad, a current detecting pad, and a body diode current detecting pad, wherein the gate pad, the source pad, the current detecting pad, and the body diode current detecting pad are connected to the first conductor, the second conductor, the third conductor, and the fourth conductor of the semiconductor substrate, respectively, and wherein the driving circuit and the at least four pads are connected by bonding wires.
