Abstract:
A power semiconductor device includes a semiconductor substrate having a first side. A plurality of active transistor cells is formed in an active area of the semiconductor substrate. Each of the plurality of active transistor cells includes a spicular trench which extends from the first side into the semiconductor substrate and has a field electrode. A gate electrode structure has a plurality of intersecting gate trenches running between the spicular trenches. The intersecting gate trenches form gate crossing regions of different shape when seen in a plan projection onto the first side of the power semiconductor device.

Claim (Index 11):
A power semiconductor device, comprising:\n a semiconductor substrate having a first side and an active area; a plurality of spaced apart spicular trenches in the active area and extending from the first side into the semiconductor substrate, each of the spicular trenches comprising a field electrode; and a plurality of intersecting gate trenches between adjacent spicular trenches, wherein, when seen in a plan projection onto the first side, the plurality of the intersecting gate trenches form a grid structure with a plurality of grid meshes to surround respective spicular trenches, wherein the gate trenches comprise respective gate electrodes, are adjacent to body regions and define channel regions in the body regions, wherein a respective channel region completely surrounds a respective spicular trench when seen in the plan projection onto the first side of the semiconductor substrate, wherein the plurality of grid meshes comprises grid meshes of different shape when seen in plan projection onto the first side.
