Abstract:
Embodiments of SiC devices and corresponding methods of manufacture are provided. In some embodiments, the SiC device has shielding regions at the bottom of some gate trenches and non-linear junctions formed with the SiC material at the bottom of other gate trenches. In other embodiments, the SiC device has the shielding regions at the bottom of the gate trenches and arranged in rows which run in a direction transverse to a lengthwise extension of the trenches. In still other embodiments, the SiC device has the shielding regions and the non-linear junctions, and wherein the shielding regions are arranged in rows which run in a direction transverse to a lengthwise extension of the trenches.
