Patent ID: 8829624

Claim:
A semiconductor structure, comprising: a power transistor including: a body region extending in a silicon region, a gate electrode insulated from the body region by a gate dielectric, a source region extending in the body region, the source region being of opposite conductivity type from the body region, a source interconnect contacting the source region, and a backside drain; and an RC snubber monolithically integrated with the power transistor in a die, the RC snubber including: a snubber electrode insulated from the silicon region by a snubber dielectric such that the snubber electrode and the silicon region form a snubber capacitor, the snubber electrode being connected to the source interconnect to form a snubber resistor between the snubber capacitor and the source interconnect, the gate electrode having a bottom surface at a depth shallower than a depth of a bottom surface of the snubber electrode, the RC snubber configured to substantially dampen output ringing when the power transistor switches states.
