| 摘要 |
According to one disclosed embodiment, a monolithic vertically integrated composite device comprises a double sided semiconductor substrate having first and second sides, a group IV semiconductor layer formed over the first side and comprising at least one group IV semiconductor device, and a group III-V semiconductor body formed over the second side and comprising at least one group III-V semiconductor device electrically coupled to the at least one group IV semiconductor device. The composite device may further comprise a substrate via and/or a through-wafer via providing electric coupling. In one embodiment, the group IV semiconductor layer may comprise an epitaxial silicon layer, and the at least one group IV semiconductor device may be a combined FET and Schottky diode (FETKY) fabricated on the epitaxial silicon layer. In one embodiment, the at least one group III-V semiconductor device may be a III-nitride high electron mobility transistor (HEMT).
