Abstract
A semiconductor device having low-leakage borderless contacts is formed by etching contact openings adjacent first and second electronic elements of opposite dopant type, conformally depositing a thin doped polysilicon layer, protecting the electronic element of similar dopant-type, removing the thin doped polysilicon layer adjacent the oppositely doped electronic element diffusing dopant from said polysilicon layer into a side wall of the electronic element of similar dopant-type, and then depositing tungsten within the contact openings.
