Abstract:
1. A monolithic microwave integrated circuit, comprising: a semiconductor substrate having a bulk resistivity equal to or greater than about 100 Ohm-cm, and having a front surface and a rear surface; at least one transistor in the semiconductor substrate and having an input terminal, an output terminal, a reference terminal, and a source region; a dielectric layer formed over the front surface and overlying the source region; at least one capacitor monolithically formed over the semiconductor substrate; at least one inductor monolithically formed over the semiconductor substrate; planar interconnections overlying the semiconductor substrate coupling the at least one transistor, capacitor, and inductor to form the monolithic integrated circuit; a first conductive through-substrate via (TSV) extending through the dielectric layer and through the semiconductor substrate; and an interlayer via formed in the first dielectric layer, the first conductive TSV electrically coupled to the source region of the transistor through the interlayer via.
