Abstract:
1. A compound semiconductor lateral PNP bipolar transistor comprising: a doped P-type planar compound semiconductor layer including a compound semiconductor-based emitter and a compound semiconductor-based collector arranged at the same level and laterally with respect to one another, wherein the emitter and the collector are separate and electrically insulated from one another; a doped N-type planar compound semiconductor layer underlying the doped P-type planar compound semiconductor layer and including a compound semiconductor-based base element electrically coupled to the separate emitter and collector; a plurality of metallic base structure connections electrically coupled to the base element and electrically insulated from the emitter and the collector; first and second metallic electrodes at a first level above the doped P-type planar compound semiconductor layer and electrically connected independently to the emitter and collector, respectively; and a plurality of base electrodes formed at a second level above the doped N-type planar compound semiconductor layer, each base electrode connected to a respective metallic base structure connection, wherein the second level is below the first level.
