  • The feasibility of fabricating dual-gate CMOS devices using the same implant to dope the polysilicon gates and to form shallow n/sup +/ and p/sup +/ source-drain junctions are demonstrated. With proper choices of polysilicon thickness, implant dose, and anneal conditions, flatband voltages approaching the degenerately doped values can be obtained simultaneously with the formation of shallow (less than 0.15 mu m) source-drain junctions. The process has been implemented in a high-performance 0.25… CONTINUE READING
