ABSTRACT:
Dual work function doping is provided by doping a selected number of gate structures having self-aligned insulating layer on top of the structures through at least one side wall of the gate structures with a first conductivity type to thereby provide an array of gate structures whereby some are doped with the first conductivity type and others of the gate structures are doped with a second and different conductivity type. Also provided is an array of gate structures whereby the individual gate structures contain self-aligned insulating layer on their top portion and wherein some of the gate structures are doped with a first conductivity type and other of the gate structures are doped with a second and different conductivity type.
