Abstract:
Machining accuracy of an IGBT region is worsened due to a height difference caused by polysilicon. Therefore, there is a problem that characteristic variation of the IGBT increases. Provided is a semiconductor device including a semiconductor substrate; a gate wiring layer provided on a front surface side of the semiconductor substrate; and a gate structure that includes a gate electrode and is provided on the front surface of the semiconductor substrate. The gate wiring layer includes an outer periphery portion that is a metal wiring layer and is provided along an outer periphery of the semiconductor substrate; and an extending portion that is a metal wiring layer, is provided extending from the outer periphery portion toward a central portion of the semiconductor substrate, and is electrically connected to the gate electrode.

Claim (Index 12):
The vertical transistor according to  claim 2 , further comprising:\n a well region of the second conductivity type, the well region including at least a bottom portion of the second vertical gate trench and extending below the first vertical gate trench, the well region being deeper than the base region and having a dopant concentration that is higher than a dopant concentration of the base region; and an interlayer insulating film in direct contact with the well region, wherein the gate wiring layer is an emitter electrode that is provided in contact with an upper surface of the interlayer insulating film, the emitter electrode covers a plurality of other first vertical gate trenches associated with other vertical transistors, and in a region outside of the first vertical gate trench and the dummy trench, the interlayer insulating film directly contacts the emitter electrode.
