Abstract:
1. A method of fabricating a semiconductor structure, comprising: (a) providing a substrate; (b) forming a dielectric layer on a top surface of said substrate; (c) forming a polysilicon layer on a top surface of said dielectric layer; (d) implanting a less than whole first portion of said polysilicon layer with N-dopant species, said N-dopant species about contained within said polysilicon layer; (e) implanting a less than whole second portion of said polysilicon layer with P-dopant species, said second portion different from said first portion, said P-dopant species about contained within said polysilicon layer; (f) implanting said first portion of said polysilicon layer with a first nitrogen containing species, said first nitrogen containing species essentially contained within said polysilicon layer; and after (a), (b), (c), (d), (e) and (f), (g) patterning said first portion of said polysilicon layer into a first polysilicon line and patterning said second portion of said polysilicon layer into a second polysilicon line.
