Patent number: 9093514Abstract: The present disclosure relates to a device and method of forming enhanced channel carrier mobility within a transistor. Silicon carbon phosphorus (SiCP) source and drain regions are formed within the transistor with cyclic deposition etch (CDE) epitaxy, wherein both resistivity and strain are controlled by substitutional phosphorus. A carbon concentration of less than approximately 1% aids in control of the phosphorus dopant diffusion. Phosphorus dopant diffusion is also controlled by an anneal step which promotes uniform doping through both source and drain, as well as lightly-doped drain regions.Type: GrantFiled: March 6, 2013Date of Patent: July 28, 2015Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Chun Hsiang Tsai, Su-Hao Liu
