Abstract:
A method for forming a first contact to a substrate between a pair of first gates having sidewall spacers and a second contact to a substrate between a pair of second gates having sidewall spacers, the method comprising:doping the substrate between the first gates to form a first source/drain region;doping the substrate between the second gates to form a second source/drain region;then, forming a polysilicon layer overlying the first gates including the sidewall spacers, the second gates including the sidewall spacers, the first source/drain region, and the second source/drain region, said polysilicon layer being self-aligned to said first gates and said second gates;doping portions, of the polysilicon layer overlying the first gates and the first source/drain region; anddoping portions of the polysilicon layer overlying the second gates and the second source/drain region.
