Abstract:
A semiconductor device includes trench structures that extend from a first surface into a semiconductor body. The trench structures include a gate structure and a contact structure that extends through the gate structure, respectively. Transistor mesas are between the trench structures. Each transistor mesa includes a body zone forming a first pn junction with a drift structure and a second pn junction with a source zone. Diode regions directly adjoin one of the contact structures form a third pn junction with the drift structure, respectively.

Claim (Index 1):
A semiconductor device comprising:\n a semiconductor body comprising a body zone, a source zone, a diode region, a drift zone and a current spread zone; and a trench structure comprising a gate structure and a contact structure, wherein the trench structure extends into the semiconductor body starting from a first surface of the semiconductor body, wherein the contact structure extends through the gate structure, wherein the diode region is arranged below the trench structure, the diode region being in contact with the contact structure, wherein the source zone and the body zone are arranged adjacent a sidewall of the trench structure, the source zone directly adjoining the body zone, and wherein the current spread zone is arranged between the body zone and the drift zone and directly adjoins the body zone.
