Abstract: A novel nickel self-aligned silicide (SALICIDE) process technology (80) adapted for CMOS devices (54) with physical gate lengths of sub-40 nm. The excess silicidation problem (52) due to edge effect is effectively solved by using a low-temperature, in-situ formed Ni-rich silicide, preferably formed in a temperature range of 260-310° C. With this new process, excess poly gate silicidation is prevented. Island diode leakage current and breakdown voltage are also improved.
