Abstract:
A semiconductor device including a semiconductor substrate and a plurality of trench structures formed on the semiconductor substrate. The semiconductor substrate includes a first element region for forming an insulated gate bipolar transistor therein, and a second element region for forming a diode therein, the semiconductor substrate constituting a drift layer. The plurality of trench structures includes a plurality of gate trench structures provided on a front surface side of the first element region, each gate trench structure having an electrode provided therein that is based on a gate potential, and a plurality of floating trench structures provided on a front surface side of the second element region, each floating trench structure having an electrode provided therein that has a floating potential.

Claim (Index 7):
The semiconductor device according to  claim 1 , wherein\n the semiconductor substrate is of a first conductivity type; and the semiconductor device further includes, in the first element region,\n a base region of a second conductivity type provided between adjacent ones of the trench structures in the first element region, and \n an emitter region of the first conductivity type provided on the base region.
