Abstract:
A method of forming a transistor device includes providing a drift layer having a first conductivity type, forming a first region in the drift layer, the first region having a second conductivity type that is opposite the first conductivity type, forming a body layer on the drift layer including the first region, forming a source layer on the body layer, forming a trench in the source layer and the body layer above the first region and extending into the first region, forming a gate insulator on the inner sidewall of the trench, and forming a gate contact on the gate insulator.

Claim (Index 12):
A transistor device, comprising:\n a drift layer having a first conductivity type; a body layer on the drift layer, the body layer having a second conductivity type opposite the first conductivity type; a trench extending into the body layer, the trench comprising a sidewall and a floor; a body contact region having the second conductivity type extending into the body layer; a first buried region having the second conductivity type in the drift layer and adjacent the floor of the trench; and a second buried region having the second conductivity type in the drift layer and in electrical contact with the body contact region, the second buried region extending towards the first buried region.
