Abstract
A semiconductor device includes needle-shaped field plate structures extending from a first surface into transistor sections of a semiconductor portion in a transistor cell area. A grid structure separates the transistor sections from each other. The grid structure includes: stripe-shaped gate edge portions extending along one edge of the transistor sections, respectively; gate node portions wider than the gate edge portions and connecting two or more of the gate edge portions, respectively; and one or more connection sections of the semiconductor portion, wherein the one or more connection sections extend between neighboring transistor sections.
