Abstract:
A semiconductor device with a metal gate is disclosed. An exemplary semiconductor device with a metal gate includes a semiconductor substrate, source and drain features on the semiconductor substrate, a gate stack over the semiconductor substrate and disposed between the source and drain features. The gate stack includes a HK dielectric layer formed over the semiconductor substrate, a plurality of barrier layers of a metal compound formed on top of the HK dielectric layer, wherein each of the barrier layers has a different chemical composition; and a stack of metals gate layers deposited over the plurality of barrier layers.

Claim (Index 15):
A device comprising:\n a first gate structure disposed over a substrate, wherein the first gate structure includes:\n a first high-k dielectric layer; \n a first nitride compound layer physically contacting the first high-k dielectric layer; \n a second nitride compound layer disposed above the first nitride compound layer, wherein the second nitride compound layer has a higher concentration of nitrogen than the first nitride compound layer; and \n a first work function metal layer disposed over the second nitride compound layer; and \n a second gate structure disposed over the substrate, wherein the second gate structure includes:\n a second high-k dielectric layer; \n a third nitride compound layer physically contacting the second high-k dielectric layer, the third nitride compound layer and the first nitride compound layer being formed of the same material; \n a fourth nitride compound layer disposed above the third nitride compound layer; and \n a second work function metal layer disposed over the fourth nitride compound layer, the second work function metal layer being different from the first work function metal layer, wherein a type of conductivity associated with the second work function metal layer is opposite a type of conductivity associated with the first work function metal layer.
