Patent ID: 7781321

Claim:
A method of forming a semiconducting device comprising: providing a substrate including a semiconducting surface, the substrate comprising a first device region and a second device region; forming a high-k dielectric layer atop the semiconducting surface of the substrate; forming a photoresist block mask atop the second device region of the substrate, wherein the first device region of the substrate is exposed; forming a first metal layer using an electroless deposition process having a deposition temperature ranging from about 15° C. to 98° C. atop the high-k dielectric layer present in the first device region of the substrate; removing the photoresist block mask to expose a portion of the high-k dielectric layer in the first device region of the substrate; forming a second metal layer using the electroless deposition process having the deposition temperature ranging from about 15° C. to 98° C. in direct contact with an entirety of the portion of the high-k dielectric layer in the second device region and in direct contact with an entirety of a portion of the first metal in the first device region of the substrate; and forming gate structures in the first device and the second device region of the substrate, wherein conductive components including the first metal layer and the second metal layer are formed only by the electroless deposition process.
