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 8):
A device comprising:\n a first gate structure including:\n a first gate dielectric layer disposed over a semiconductor substrate, the first gate dielectric layer having a u-shaped profile defining a recess; \n a first metal nitride compound layer disposed within the recess such that the first metal nitride compound layer physically contacts the gate dielectric layer; \n a second metal nitride compound layer disposed within the recess on the first metal nitride compound layer; and \n a first gate electrode layer disposed with the recess on the second metal nitride compound layer, wherein a top surface of the first gate electrode layer is substantially coplanar with a top surface of the gate dielectric layer; and \n a second gate structure including:\n a second gate dielectric layer disposed over the semiconductor substrate; \n a third metal nitride compound layer formed on top of the second gate dielectric layer such that the third metal nitride compound layer physically contacts the second gate dielectric layer, wherein the first metal nitride compound layer and the third metal nitride compound layer are formed of the same material; \n a fourth metal nitride compound layer formed on top of the third metal nitride compound layer; and \n a second gate electrode layer disposed over the fourth metal nitride compound layer, wherein the first gate electrode layer is associated with a first type of conductivity and the second gate electrode layer is associated with a second type of conductivity that is opposite the first type of conductivity.
