SEMICONDUCTOR DEVICE INCLUDING A POWER TRANSISTOR DEVICE AND BYPASS DIODE

摘要

A semiconductor device includes a vertical FET device and a Schottky bypass diode. The vertical FET device includes a gate contact, a source contact, and a drain contact. The gate contact and the source contact are separated from the drain contact by at least a drift layer. The Schottky bypass diode is coupled between the source contact and the drain contact and monolithically integrated adjacent to the vertical FET device such that a voltage placed between the source contact and the drain contact is distributed throughout the drift layer by the Schottky bypass diode in such a way that a voltage across each one of a plurality of P-N junctions formed between the source contact and the drain contact within the vertical FET device is prevented from exceeding a barrier voltage of the respective P-N junction.
