Abstract:
1. A method of making a semiconductor device, comprising: providing a substrate; forming a gate and a pair of source/drain doped regions on the substrate, wherein the gate and the pair of source/drain doped regions each independently comprise a doped silicon layer; blanketly depositing a NiPt layer to cover the gate and the pair of source/drain doped regions; blanketly depositing a cap layer on the NiPt layer; performing a first rapid thermal process on the substrate to allow Ni of the NiPt layer to react with silicon of the silicon layer to form a Ni performing a selective etching process to remove unreacted NiPt or the cap layer; performing a second rapid thermal process on the substrate to allow the Ni performing an ion implantation to implant a dopant into the Ni
