Method for fabricating metal gate devices and resulting structures

A method for fabricating a semiconductor component includes forming an interlayer dielectric (ILD) layer on a substrate, forming a trench in the interlayer dielectric layer, forming a metal gate in the trench, removing a portion of the metal gate protruding from the ILD layer, reacting a reducing ga...

Zusammenfassung:	A method for fabricating a semiconductor component includes forming an interlayer dielectric (ILD) layer on a substrate, forming a trench in the interlayer dielectric layer, forming a metal gate in the trench, removing a portion of the metal gate protruding from the ILD layer, reacting a reducing gas with the metal gate, and removing a top portion of the metal gate.
