Abstract
In a general aspect, a semiconductor device can include a substrate of a first conductivity type, an active region disposed in the substrate, and a termination region disposed in the substrate adjacent to the active region. The termination region can include a junction termination extension (JTE) of a second conductivity type, where the second conductivity type is opposite the first conductivity type. The JTE can have a first depletion stopper region disposed in an upper portion of the JTE, a second depletion stopper region disposed in a lower portion of the JTE, and a high carrier mobility region disposed between the first depletion stopper region and the second depletion stopper region.
