    摘要: A lateral heterojunction bipolar transistor (HBT) is formed on a semiconductor-on-insulator substrate. The HBT includes a base including a doped silicon-germanium alloy base region, an emitter including doped silicon and laterally contacting the base, and a collector including doped silicon and laterally contacting the base. Because the collector current is channeled through the doped silicon-germanium base region, the HBT can accommodate a greater current density than a comparable bipolar transistor employing a silicon channel. The base may also include an upper silicon base region and/or a lower silicon base region. In this case, the collector current is concentrated in the doped silicon-germanium base region, thereby minimizing noise introduced to carrier scattering at the periphery of the base. Further, parasitic capacitance is minimized because the emitter-base junction area is the same as the collector-base junction area.

The structure includes a semiconductor substrate having at least a pair of neighboring first shallow trench isolation (STI) regions disposed therein. The pair of neighboring first STI regions defines an active area in the substrate. The structure also includes a collector disposed in the in the active area of the semiconductor substrate, a base layer disposed atop a surface of the semiconductor substrate in the active area, and a raised extrinsic base disposed on the base layer. In accordance with the present, the raised extrinsic base has an opening to a portion of the base layer. An emitter is located in the opening and extending on a portion of the patterned raised extrinsic base; the emitter is spaced apart and isolated from the raised extrinsic base. Moreover, and in addition to the first STI region, a second shallow trench isolation (STI) region is present in the semiconductor substrate which extends inward from each pair of said first shallow trench isolation regions towards said collector. The second STI region has an inner sidewall surface that is sloped. In some embodiments, the base is completely monocrystalline.
