    摘要: The present invention provides, in one embodiment, a process for fabricating a metal oxide semiconductor (MOS) device (100). The process includes forming a gate (120) on a substrate (105) and forming a source/drain extension (160) in the substrate (105). Forming the source/drain extension (160) comprises an abnormal-angled dopant implantation (135) and a dopant implantation (145). The abnormal-angled dopant implantation (135) uses a first acceleration energy and tilt angle of greater than about zero degrees. The dopant implantation (145) uses a second acceleration energy that is higher than the first acceleration energy. The process also includes performing an ultrahigh high temperature anneal of the substrate (105), wherein a portion (170) of the source/drain extension (160) is under the gate (120).

    摘要: A method of forming a semiconductor device includes forming one or more sidewall spacer layers on the outer surface of a gate stack. At least one region of an at least partially formed semiconductor device is doped. First and second sidewall bodies are formed on opposing sides of the gate stack. The formation of the first and second sidewall bodies includes forming a first sidewall-forming layer on the outward surface of the gate stack and the sidewall spacer layers, exposing the semiconductor device to a heating cycle in a single wafer reactor, and forming a second sidewall-forming layer on the outward surface of the first sidewall-forming layer. The formation of the second sidewall-forming layer occurs in an environment that substantially minimizes dopant loss and deactivation in the at least one region of the partially formed semiconductor device.
