Abstract:
A semiconductor device includes a trench extending into a first main surface of a semiconductor substrate, and a gate electrode and a gate dielectric in the trench. The gate dielectric separates the gate electrode from the semiconductor substrate. A first region having a first conductivity type is formed in the semiconductor substrate at the first surface adjacent the trench. A second region having a second conductivity type is formed in the semiconductor substrate below the first region adjacent the trench. A third region having the first conductivity type is formed in the semiconductor substrate below the second region adjacent the trench. A contact opening in the semiconductor substrate extends into the second region. An electrically insulative spacer is disposed on sidewalls of the semiconductor substrate formed by the contact opening, and an electrically conductive material in the contact opening adjoins the electrically insulative spacer on the sidewalls.

Claim (Index 11):
The semiconductor device of  claim 9 , further comprising a field plate in the trench below the gate electrode, wherein the field plate is electrically insulated from the gate electrode.
