    摘要: The present invention provides a “collector-less” silicon-on-insulator (SOI) bipolar junction transistor (BJT) that has no impurity-doped collector. Instead, the inventive vertical SOI BJT uses a back gate-induced, minority carrier inversion layer as the intrinsic collector when it operates. In accordance with the present invention, the SOI substrate is biased such that an inversion layer is formed at the bottom of the base region serving as the collector. The advantage of such a device is its CMOS-like process. Therefore, the integration scheme can be simplified and the manufacturing cost can be significantly reduced. The present invention also provides a method of fabricating BJTs on selected areas of a very thin BOX using a conventional SOI starting wafer with a thick BOX. The reduced BOX thickness underneath the bipolar devices allows for a significantly reduced substrate bias compatible with the CMOS to be applied while maintaining the advantages of a thick BOX underneath the CMOS.

    摘要: An electronic circuit comprises a bipolar transistor that includes a conductive back electrode, an insulator layer over the conductive back electrode and a semiconductor layer of either an n-type or p-type material over the insulator layer. The semiconductor layer includes a doped region, used as the collector and a heavily doped region, bordering the doped region, used as a reachthrough between the insulator layer and the collector contact electrode. A majority-carrier accumulation layer is induced adjacent to the insulator in the doped region of the collector by the application of a bias voltage to the back electrode.

    摘要: A stress-transmitting dielectric layer is formed on the at least one PFET and the at least one NFET. A tensile stress generating film, such as a silicon nitride, is formed on the at least one NFET by blanket deposition and patterning. A compressive stress generating film, which may be a refractive metal nitride film, is formed on the at least one PFET by a blanket deposition and patterning. An encapsulating dielectric film is deposited over the compress stress generating film. The stress is transferred from both the tensile stress generating film and the compressive stress generating film into the underlying semiconductor structures. The magnitude of the transferred compressive stress from the refractory metal nitride film may be from about 5 GPa to about 20 GPa. The stress is memorized during an anneal and remains in the semiconductor devices after the stress generating films are removed.
