摘要： The present invention provides a manufacturing method for a semiconductor device having epitaxial source/drain regions, in which a diffusion barrier layer of the source/drain regions made of epitaxial silicon-carbon or germanium silicon-carbon are added on the basis of epitaxially growing germanium-silicon of the source/drain regions in the prior art process, and the introduction of the diffusion barrier layer of the source/drain regions prevents diffusion of the dopant in the source/drain regions, thus mitigating the SCE and DIBL effect. The use of the diffusion barrier layer for the source/drain regions can also reduce the dosage of HALO implantation in the subsequent step, thus if HALO is performed before epitaxial growth of the source/drain regions, impact on the surfaces of the source/drain regions can be alleviated; if HALO is performed after epitaxial growth of the source/drain regions, the stress release effect of the epitaxial layer of the source drain/regions caused by the implantation can be reduced as much as possible.
摘要翻译：本发明提供了一种具有外延源极/漏极区域的半导体器件的制造方法，其中基于外延生长锗添加由外延硅 - 碳或锗硅 - 碳制成的源极/漏极区的扩散阻挡层在现有技术的工艺中源极/漏极区域的硅，以及源极/漏极区域的扩散阻挡层的引入防止了掺杂剂在源/漏区域中的扩散，从而减轻了SCE和DIBL效应。用于源极/漏极区域的扩散阻挡层的使用也可以降低后续步骤中的HALO注入的剂量，因此如果在源极/漏极区域的外延生长之前执行HALO，则冲击源极/漏极地区可以缓解; 如果在源/漏区的外延生长之后执行HALO，则可以尽可能地减少由注入引起的源漏极/区域的外延层的应力释放效应。

摘要： The present invention relates to a method of manufacturing a semiconductor device for improving the spacer mask. In the present invention, a barrier layer and a sacrificial layer are formed, and the portions of the upper part of the spacer whose left and right sides differ greatly are ground away to leave the portion similar to a rectangle at the bottom of the spacer, which is used as the mask to perform the subsequent spacer masking technology. Thus the undesirable influences to the subsequent etching caused by the asymmetric profile of the spacer can be reduced as much as possible.

摘要： A method of manufacturing a semiconductor device is disclosed. In one embodiment, the method comprises: forming a gate stack on a substrate; etching the substrate on both sides of the gate stack to form C-shaped source/drain grooves; and wet-etching the C-shaped source/drain grooves to form Σ-shaped source/drain grooves. With this method, it is possible to effectively increase stress applied to a channel region, to accurately control a depth of the source/drain grooves, and to reduce roughness of side walls and bottom portions of the grooves and thus reduce defects by etching the C-shaped source/drain grooves and then further wet-etching them to form the Σ-shaped source/drain grooves.
