Abstract:
1. A method for forming a replacement metal gate (RMG) of a semiconductor device, the method comprising: providing a set of field effect transistors (FET) formed over a substrate, each of the set of FETs having a recess formed therein; forming a high-k layer over the semiconductor device and within each recess; forming a barrier layer over the high-k layer; forming an organic dielectric layer (ODL) within each recess; recessing the ODL to a desired height within each recess; removing the high-k layer and the barrier layer from atop the semiconductor device selective to the ODL within each recess; removing the ODL from within each recess; selectively growing a work-function metal (WFM) within one of the recesses; and forming a metal material within each recess.
