Abstract:
A semiconductor device includes a semiconductor substrate having first and second main surfaces, a first region formed in a surface layer of the first main surface, a drift layer disposed adjacent to the first region, a charge accumulation region having a higher concentration than the drift region, and a trench gate including a trench penetrating the first region and the charge accumulation region, and a gate electrode formed in the trench. The trench gate includes a main trench having a gate electrode to which a gate voltage is applied, and a dummy trench having a gate electrode to which a voltage different from the main trench is applied. The main trench and the dummy trench sandwiches the charge accumulation region, and a contact area S 1  between the dummy trench and the charge accumulation region is larger than a contact area S 2  between the main trench and the charge accumulation region.

Claim (Index 5):
The semiconductor device according to  claim 4 , wherein\n the dummy trench includes a meandering shape that has a plurality of turning back portions in a direction orthogonal to the extension direction of the main trench in the front view of the first main surface.
