Abstract
The present disclosure provides a semiconductor device with a profiled work-function metal gate electrode. The semiconductor structure includes a metal gate structure formed in an opening of an insulating layer. The metal gate structure includes a gate dielectric layer, a barrier layer, a work-function metal layer between the gate dielectric layer and the barrier layer and a work-function adjustment layer over the barrier layer, wherein the work-function metal has an ordered grain orientation. The present disclosure also provides a method of making a semiconductor device with a profiled work-function metal gate electrode.
