Abstract:
In an embodiment, a semiconductor device includes a semiconductor body having a field effect transistor device with an active region and an edge termination region that surrounds the active region on all sides. The active region includes a first serpentine trench in the semiconductor body, a first field plate in the first serpentine trench, a second serpentine trench in the semiconductor body, and a second field plate in the second serpentine trench. The first serpentine trench is separate and laterally spaced apart from the second serpentine trench.

Claim (Index 1):
A semiconductor device, comprising:\n a transistor device, comprising: a semiconductor body comprising a first major surface; a first trench in the first major surface, the first trench having at least two transverse portions that are spaced apart by a distance, wherein adjacent ones of the transverse portions are connected by a longitudinal portion such that the first trench has a meandering form; a second trench in the first major surface, the second trench laterally enclosing the first trench; a third trench in the first major surface, wherein the third trench extends from the second trench between two transverse portions of the first trench and has a distal end spaced apart from the longitudinal portion of the first trench that connects the two transverse portions; a continuous mesa formed between the first trench, the second trench and the third trench; and a field plate and a gate electrode in each of the first trench and the third trench.
