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).
