摘要： A semiconductor substrate having transistor structures and test structures with spacing between the transistor structures smaller than the spacing between the test structures is provided. A first iteratively performed deposition and etch process includes: depositing a first doped epitaxial layer having a first concentration of a dopant over the semiconductor substrate, and etching the first doped epitaxial layer. A second iteratively performed deposition and etch process includes: depositing a second doped epitaxial layer having a second concentration of the dopant higher than the first concentration over the semiconductor substrate, and etching the second doped epitaxial layer. The first concentration results in a first net growth rate over the transistor structures and the second concentration results in a lower, second net growth rate over the test structures than the transistor structures, resulting in reduced pattern loading.

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。
