Abstract
Silicon-based, submicron-dimensioned MOS and/or CMOS transistor devices having substantially reduced source/drain junction-to-semiconductor substrate capacitance are formed by implanting oxygen atoms and/or molecules just below source/drain implant regions. Implantation conditions are selected to provide a peak oxygen implant concentration at a depth just below the ultimate source/drain junction depth. Subsequent thermal processing at elevated temperature results in source/drain dopant diffusion/activation and formation of a silicon oxide barrier layer or stratum just below the ultimate source/drain junction depth, thereby substantially reducing junction-to-substrate capacitance of refractory metal silicide-contact devices.
