摘要:
The present invention provides a method for patterning a metal gate electrode and a method for manufacturing an integrated circuit including the same. The method for patterning the metal gate electrode, among other steps, includes forming a metal gate electrode layer (220) over a gate dielectric layer (210) located on a substrate (110), and patterning the gate electrode layer (220) using a combination of a dry etch process (410) and a wet etch process (510).
