摘要:
The present invention provides method of forming a gate dielectric that includes forming a metal source layer (210) comprising a metal and at least one nonmetallic element over a substrate (110). The metal source layer (210) is formed having a composition rich in the metal. A dielectric layer (310) comprising the metal is formed over the metal source layer (210).
