Abstract : The process of the present invention produces CMOS bulk circuits allowing any treatment of the field oxide up to and including the channel edge; allows p-field boron implant to increase parasitic threshold eliminates the bird's beak oxide encroachment which reduces channel width and recessed oxide along the channel edge; provides for a self-aligned p-field implant; and provides for a spacer use on a self-aligned p-field implant to offset effects of side diffusion and oxide undercut.
