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 5):
The vertical transistor according to  claim 1 , wherein:\n the first vertical gate trench extends in a first direction below an extending portion of the gate wiring layer, the gate wiring layer is directly connected to the first gate electrode of the first vertical gate trench extending in the first direction, and the first vertical gate trench is provided with a lattice shape formed by intersections of portions extending in the first direction and portions extending orthogonal to the first direction.
