Abstract:
1. An apparatus comprising: a semiconductor layer of a first conductivity type, the semiconductor layer having a top-side surface; a well region of a second conductivity type opposite the first conductivity type, the well region being disposed in an upper portion of the semiconductor layer; a gate trench disposed in the semiconductor layer, the gate trench extending through the well region; a drain contact disposed, at least in part, on the top-side surface of the semiconductor layer, the drain contact being adjacent to the well region; an isolation trench disposed between the drain contact and the gate trench in the semiconductor layer, the isolation trench extending through the well region; a termination trench disposed in the semiconductor layer and disposed between the gate trench and the isolation trench, the termination trench extending through the well region; and at least one termination electrode disposed in the termination trench.
