    摘要: The present invention provides, in one embodiment, a method of fabricating a semiconductor device (100). The method comprises growing an oxide layer (120) on a gate structure (114) and a substrate (102) and implanting a dopant (124) into the substrate (102) and the oxide layer (120). Implantation is such that a portion of the dopant (124) remains in the oxide layer (120) to form an implanted oxide layer (126). The method further includes depositing a protective oxide layer (132) on the implanted oxide layer (126) and forming etch-resistant off-set spacers (134). The etch-resistant off-set spacers (134) are formed adjacent sidewalls of the gate structure (114) and on the protective oxide layer (132). The etch resistant off-set spacers having an inner perimeter (135) adjacent the sidewalls and an opposing outer perimeter (136). The method also comprises removing portions of the protective oxide layer (132) lying outside the outer perimeter (136) of the etch-resistant off-set spacers (134). Other embodiments of the present invention include a transistor device (200) and method of manufacturing an integrated circuit (300).

    摘要: The present invention provides, in one embodiment, a method of fabricating a semiconductor device (100). In one embodiment, the method includes growing an oxide layer 120 from a substrate 104, 106 over a first dopant region 122 and a second dopant region 128, implanting a first dopant through the oxide layer 120, into the substrate 104 in the first dopant region 122, and adjacent a gate structure 114, and substantially removing the oxide layer 120 from the substrate within the second dopant region 128. Subsequent to the removal of the oxide layer 120 in the second dopant region 128, a second dopant that is opposite in type to the first dopant is implanted into the substrate 106 and within the second dopant region 128 and adjacent a gate structure 114.
