Abstract:
The present disclosure provides a method of forming a semiconductor structure with a metal gate. The semiconductor structure is formed by first fabricating fins over a semiconductor substrate, followed by a formation of a source and a drain recess. A source and a drain region may then be deposited into the source and the drain recess. The gate structure may be deposited into the region between the fins. The gate structure includes dielectric and metallic layers. In the regions between the fins, the gate structure is isolated from the source and the drain region by an insulating layer.
