  • Semiconductor device having localized charge balance structure and method
    Patent number: 10090380
    Abstract: In one embodiment, a semiconductor substrate is provided having a localized superjunction structure extending from a major surface. A doped region is then formed adjacent the localized superjunction structure to create a charge imbalance therein. In one embodiment, the doped region can be an ion implanted region formed within the localized superjunction structure. In another embodiment, the doped region can be an epitaxial layer having a graded dopant profile adjoining the localized superjunction structure. The charge imbalance can improve, among other things, unclamped inductive switching (UIS) performance.
    Type: Grant
