Ni(Pt) silicide with improved thermal stability for application in DRAM periphery and replacement metal gate devices
A NiPt silicide stable with long 600 and 800C anneals, as required by DRAM periphery. Thermally stable silicide by pre-amorphisation+C implant+laser anneal. TSS successfully integrated in low voltage CMOS HKMG devices suitable for DRAM PERI. Thermal stability can be obtained using a spike anneal rather than a laser anneal.
