Abstract:
In mesa regions between adjacent trenches disposed in an n − -type drift layer and in which a first gate electrode is disposed via a first gate insulating film, a p-type base region and a floating p + -type region of which a surface is partially covered by a second gate electrode via a second gate insulating film are disposed. An emitter electrode contacts the p-type base region and an n + -type emitter region, and is electrically isolated from first and second gate electrodes and the floating p + -type region by an interlayer insulating film covering the first and second gate electrodes and a portion of the floating p + -type region not covered by the second gate electrode. Thus, turn-on dV/dt controllability by the gate resistance Rg may be improved.

Claim (Index 2):
The method of manufacturing a semiconductor device according to  claim 1 , further comprising:\n depositing an insulating layer on the interlayer insulating film so as to increase a thickness of the interlayer insulating film, after selectively removing the interlayer insulating film and the gate insulating film; and reducing the thickness of the interlayer insulating film at a first portion excluding a second portion covering the second semiconductor region, leaving the thickness of the interlayer insulating film at the second portion, and again exposing the first semiconductor region and the third semiconductor region, after depositing the insulating layer and before forming the first electrode.
