Abstract
A semiconductor device includes a semiconductor region with a charge balance region on a junction blocking region, which has a lower doping concentration. A trench structure having an insulated shield electrode and an insulated gate electrode is provided in the semiconductor region. The semiconductor device further includes one or more features configured to improve operating performance. The features include terminating the trench structure in the junction blocking region, providing a localized doped region adjoining a lower surface of a body region and spaced apart from the trench structure, disposing a notch proximate to the lower surface of the body region, and/or configuring the insulated shield electrode to have a wide portion adjoining a narrow portion.
