摘要： Methods of fabricating bipolar junction transistors, bipolar junction transistors, and design structures for a bipolar junction transistor. A first portion of the intrinsic base layer is masked while a second portion of an intrinsic base layer is etched. As a consequence of the masking, the second portion of the intrinsic base layer is thinner than the first portion of the intrinsic base layer. An emitter and an extrinsic base layer are formed in respective contacting relationships with the first and second portions of the intrinsic base layer.

摘要： The invention includes methods of fabricating a bipolar transistor that adds a silicon germanium (SiGe) layer or a third insulator layer of, e.g., high pressure oxide (HIPOX), atop an emitter cap adjacent the intrinsic base prior to forming a link-up layer. This addition allows for removal of the link-up layer using wet etch chemistries to remove the excess SiGe or third insulator layer formed atop the emitter cap without using oxidation. In this case, an oxide section (formed by deposition of an oxide or segregation of the above-mentioned HIPOX layer) and nitride spacer can be used to form the emitter-base isolation. The invention results in lower thermal cycle, lower stress levels, and more control over the emitter cap layer thickness, which are drawbacks of the first embodiment. The invention also includes the resulting bipolar transistor structure.

摘要翻译： 本发明包括制造双极晶体管的方法，该双极晶体管在形成连接层之前，将硅锗（SiGe）层或例如高压氧化物（HIPOX）的第三绝缘体层与邻近本征基极的发射极帽顶上相加 。 该添加允许使用湿蚀刻化学去除连接层，以去除在不使用氧化的情况下形成在发射极帽顶上的多余SiGe或第三绝缘体层。 在这种情况下，可以使用氧化物部分（通过沉积氧化物或上述HIPOX层的分离）和氮化物间隔物形成发射极 - 基极隔离。 本发明导致较低的热循环，较低的应力水平和对发射极盖层厚度的更多控制，这是第一实施例的缺点。 本发明还包括所得到的双极晶体管结构。

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： Junction field-effect transistors, methods for fabricating junction field-effect transistors, and design structures for a junction field-effect transistor. A source and a drain of the junction field-effect transistor are comprised of a semiconductor material grown by selective epitaxy and in direct contact with a top surface of a semiconductor layer. A gate is formed that is aligned with a channel laterally disposed in the semiconductor layer between the source and the drain. The source, the drain, and the semiconductor layer are each comprised of a second semiconductor material having an opposite conductivity type from a first semiconductor material comprising the gate.

摘要： Methods for fabricating bipolar junction transistors with self-aligned emitter and extrinsic base, bipolar junction transistors made by the methods, and design structures for a BiCMOS integrated circuit. The bipolar junction transistor is fabricated using a sacrificial emitter pedestal that provides a sacrificial mandrel promoting self-alignment between the emitter and the extrinsic base. The sacrificial emitter pedestal is subsequently removed to open an emitter window extending to the intrinsic base. An emitter is formed in the emitter window that lands on the intrinsic base.
