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 14):
The transistor device of  claim 12 , wherein an upper portion of the drift layer adjacent the body layer is doped with first conductivity type dopants more heavily than a lower portion of the drift layer.
