摘要： The present invention provides a method of forming asymmetric field-effect-transistors. The method includes forming a gate structure on top of a semiconductor substrate, the gate structure including a gate stack and spacers adjacent to sidewalls of the gate stack, and having a first side and a second side opposite to the first side; performing angled ion-implantation from the first side of the gate structure in the substrate, thereby forming an ion-implanted region adjacent to the first side, wherein the gate structure prevents the angled ion-implantation from reaching the substrate adjacent to the second side of the gate structure; and performing epitaxial growth on the substrate at the first and second sides of the gate structure. As a result, epitaxial growth on the ion-implanted region is much slower than a region experiencing no ion-implantation. A source region formed to the second side of the gate structure by the epitaxial growth has a height higher than a drain region formed to the first side of the gate structure by the epitaxial growth. A semiconductor structure formed thereby is also provided.

摘要： A self-aligned bipolar transistor and method of fabricating the same are disclosed. In an embodiment, a substrate and an intrinsic base are provided, followed by a first oxide layer, and an extrinsic base over the first oxide layer. A first opening is formed, exposing a portion of a surface of the extrinsic base. Sidewall spacers are formed in the first opening, and a self-aligned oxide mask is selectively formed on the exposed surface of the extrinsic base. The spacers are removed, and using the self-aligned oxide mask, the exposed extrinsic base and the first oxide layer are etched to expose the intrinsic base layer, forming a first and a second slot. A silicon layer stripe is selectively grown on the exposed intrinsic and/or extrinsic base layers in each of the first and second slots, substantially filling the respective slot.

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.
摘要翻译：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。

摘要： A semiconductor structure including a bi-layer nFET embedded stressor element is disclosed. The bi-layer nFET embedded stressor element can be integrated into any CMOS process flow. The bi-layer nFET embedded stressor element includes an implant damaged free first layer of a first epitaxy semiconductor material having a lattice constant that is different from a lattice constant of a semiconductor substrate and imparts a tensile strain in a device channel of an nFET gate stack. Typically, and when the semiconductor is composed of silicon, the first layer of the bi-layer nFET embedded stressor element is composed of Si:C. The bi-layer nFET embedded stressor element further includes a second layer of a second epitaxy semiconductor material that has a lower resistance to dopant diffusion than the first epitaxy semiconductor material. Typically, and when the semiconductor is composed of silicon, the second layer of the bi-layer nFET embedded stressor element is composed of silicon. Only the second layer of the bi-layer nFET embedded stressor element includes the implanted source/drain regions.
