Classification: CPC G  H | IPC G  H

Claim 20:
21. The semiconductor device of claim 20, wherein the electrical device formed in the active region of the semiconductor body is a vertical power transistor, wherein a gate electrode and a source electrode for the vertical power transistor are disposed at a first main surface of the first semiconductor die, wherein a drain electrode for the vertical power transistor is disposed at a second main surface of the first semiconductor die opposite the first main surface, wherein the second main surface of the first semiconductor die faces the second semiconductor die, and wherein the drain electrode has an opening to permit light emitted by carrier recombination at the interface when the vertical power transistor is driven between accumulation and inversion to propagate into the main surface of the second semiconductor die that faces the first semiconductor die.
