Abstract
Sub-micron dimensioned, ultra-shallow junction MOS and/or CMOS transistor devices have been reduced or a minimal junction leakage are formed by a salicide process wherein carbonaceous residue on silicon substrate surfaces resulting from reactive plasma etching for sidewall spacer formation is removed prior to salicide processing. Embodiments include forming a sacrificial oxide and removing the sacrificial oxide to remove the carbonaceous residues and anneal out damage to the silicon substrate. Subsequently formed silicide regions on the source and drain regions have improved quality.
