Abstract:
1. A stacked composite device having a composite drain, a composite source, and a composite gate, said stacked composite device comprising: a group IV lateral transistor; a group III-V transistor stacked over said group IV lateral transistor; a drain electrode of said group IV lateral transistor being in direct contact with a source electrode of said group III-V transistor, said source electrode of said group III-V transistor situated on said drain electrode of said group IV lateral transistor; a source of said group IV lateral transistor being coupled to a gate of said group III-V transistor to provide said composite source on a top side of said stacked composite device; a drain of said group III-V transistor providing said composite drain on said top side of said stacked composite device; a gate of said group IV lateral transistor providing said composite gate on said top side of said stacked composite device; a substrate of said group IV lateral transistor being on a bottom side of said stacked composite device; one of a drain electrode of said group III-V transistor and said source electrode of said group III-V transistor being electrically coupled to a respective drain or source pad on an opposite side of said group III-V transistor by at least one through-substrate via.
