Abstract:
A method of manufacturing a metal gate is provided. The method includes providing a substrate. Then, a gate dielectric layer is formed on the substrate. A multi-layered stack structure having a work function metal layer is formed on the gate dielectric layer. An O2 ambience treatment is performed on at least one layer of the multi-layered stack structure. A conductive layer is formed on the multi-layered stack structure.
