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.
