Abstract: A method for forming a replacement metal gate structure sharing a single work function metal for both the N-FET and the P-FET gates. The method oppositely dopes a high-k material of the N-FET and P-FET gate, respectively, using a single lithography step. The doping allows use of a single work function metal which in turn provides more space in the metal gate opening so that a bulk fill material may occupy more volume of the opening resulting in a lower resistance gate.
