Abstract
An electronic device can include a termination structure that includes a substrate, a semiconductor layer, and a first trench. The substrate includes a semiconductor material of a first conductivity type. The semiconductor layer has a second conductivity type opposite the first conductivity type and overlies the substrate and has a primary surface. The first trench extends through a majority of a thickness of the semiconductor layer. In an embodiment, a body extension region of the second conductivity type is adjacent to the primary surface and spaced apart from the first trench. In another embodiment, a doped region of the first conductivity type is adjacent to the primary surface and abuts the first trench. In a further embodiment, the termination structure can include a second trench extending through a majority of the thickness of the semiconductor layer and a doped region is spaced apart from the first and second trenches.
