    • An inverted polycide extrinsic base contact serves as a diffusion source, yet still has low resistivity and is readily etchable down to silicon by techniques useful in manufacturing integrated circuits. The extrinsic base contact layer is made up of a metal silicide (e.g. WSi.sub.2) with an overlying doped polysilicon layer with coextensive apertures through doped polysilicon and metal silicide layers defining the emitter and intrinsic base region.The extrinsic base region is formed by diffusing boron impurities from the p.sup.+ polysilicon layer through the silicide layer. The silicide layer is of a metal silicide such as tungsten silicide (WSi.sub.2). The polysilicon layer acts as a diffusion source, since appropriate dopants (e.g., boron) diffuse rapidly through the metal silicide. Both the top surface of the p.sup.+ polysilicon layer and the sidewall edges of the polysilicon and silicide layers are covered by an insulating layer (e.g. SiO.sub.2) which also separates the emitter contact from the base contact layers.
    • 反向多硅化物非本征基极接触用作扩散源,但仍具有低电阻率,并且通过可用于制造集成电路的技术容易地向硅蚀刻。 外部基极接触层由金属硅化物(例如WSi2)与具有共同延伸孔的上覆掺杂多晶硅层组成,掺杂多晶硅和金属硅化物层限定发射极和本征基极区。 通过从p +多晶硅层通过硅化物层扩散硼杂质形成非本征基区。 硅化物层是诸如硅化钨(WSi2)之类的金属硅化物。 多晶硅层充当扩散源,因为合适的掺杂剂(例如硼)迅速扩散通过金属硅化物。 p +多晶硅层的顶表面和多晶硅和硅化物层的侧壁边缘都被绝缘层(例如SiO 2)覆盖,绝缘层也将发射极接触与基极接触层分开。

    • A germanium lateral bipolar junction transistor (BJT) is formed employing a germanium-on-insulator (GOI) substrate. A silicon passivation layer is deposited on the top surface of a germanium layer in the GOI substrate. Shallow trench isolation structures, an extrinsic base region structure, and a base spacer are subsequently formed. A germanium emitter region, a germanium base region, and a germanium collector region are formed within the germanium layer by ion implantation. A silicon emitter region, a silicon base region, and a silicon collector region are formed in the silicon passivation layer. After optional formation of an emitter contact region and a collector contact region, metal semiconductor alloy regions can be formed. A wide gap contact for minority carriers is provided between the silicon base region and the germanium base region and between the silicon emitter region and the germanium emitter region.

    • 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.
    • 在绝缘体上半导体衬底上形成横向异质结双极晶体管(HBT)。 HBT包括基底,其包括掺杂的硅 - 锗合金基底区域,包括掺杂硅并且横向接触基底的发射体,以及包括掺杂硅并且横向接触基底的收集器。 因为集电极电流被引导通过掺杂的硅 - 锗基区,所以与使用硅沟道的可比较的双极晶体管相比,HBT可以容纳更大的电流密度。 基底还可以包括上硅基区和/或下硅基区。 在这种情况下,集电极电流集中在掺杂的硅 - 锗基区域中,从而最小化引入到基极周边的载流子散射的噪声。 此外,寄生电容被最小化,因为发射极 - 基极结面积与集电极 - 基极结面积相同。
