An alternative doping technique of polysilicon gate for sub-micron CMOS/BiCMOS devices

This paper presents alternative techniques of polysilicon doping using POCl3 and ion implantation for gate electrode of sub-micron CMOS/BiCMOS devices during the technology transfer to local fab. The in-situ doping sheet resistance (Rs) value is use as a reference at range of 20 to 25 Ω/□. The polys...
