Abstract
High voltage semiconductor devices include a drift layer region underlying a field gate electrode, the drift layer region having a selected charge density of lesser magnitude than the charge density of the remainder of the drift layer. This tailoring of the charge density of the drift layer region lowers the pinch-off voltage of a MOSFET inherent in the drift layer region. This lower pinch-off voltage decreases the potential of a device buried-layer when the device is in a reverse blocking mode of operation.
