Electrical characteristics of shallow (∼ 3500 Å) arsenic-implanted junctions have been determined for a wide range of process conditions and have been compared with arsenic diffused junctions obtained using a doped oxide diffusion source. Process conditions examined included various pre-and post-implantation gettering cycles, anneal temperatures (600 to 900°C), dose (
