Abstract

A method for processing an integrated circuit includes forming N-type and P-type gate all around transistors and core gate all around transistors. The method deposits a first metal gate layer for the P-type transistors and a second metal gate layer for the N-type transistors. The method forms a passivation layer in-situ with the metal gate layer of the P-type transistors.
