Abstract
A method forming a gate dielectric over a substrate, and forming a metal gate structure over the semiconductor substrate and the gate dielectric. The metal gate structure includes a first metal material. The method further includes forming a seal on sidewalls of the metal gate structure. The method further includes forming a dielectric film on the metal gate structure, the dielectric film including a first metal oxynitride comprising the first metal material and directly on the metal gate structure without extending over the seal formed on sidewalls of the metal gate structure.
