Abstract

An integrated circuit device is presented. The integrated circuit device of the present invention comprises a semiconductor substrate having a combination of transistor gates formed using a conventional dielectric-capped gate stack for self-aligned diffusion contacts (SAC) as well as a transistor gate structure formed by removing the dielectric-cap gate stack from selected regions of the semiconductor substrate and replacing the dielectric-cap gate stack with a second gate conductor which is patterned using a damascene process.
