Abstract:
A complementary metal-oxide semiconductor (CMOS) circuit and a method of fabricating the device are described. The circuit includes an n-channel field effect transistor (nFET), the nFET including a high-k dielectric layer on an interlayer. The CMOS circuit also includes a p-channel field effect transistor (pFET), the pFET including the high-k dielectric layer on the interlayer and additionally including an aluminum-based cap layer between the high-k dielectric layer and a pFET work function setting metal. Metal atoms from the cap layer do not intermix with the interlayer.

Claim (Index 1):
A method of fabricating a semiconductor device including a p-channel field effect transistor (pFET), the method comprising:\n forming an interlayer and a high-k dielectric layer for the pFET and additionally for an n-channel field effect transistor (nFET) of the semiconductor device; depositing an aluminum-based cap layer over the high-k dielectric layer for the pFET and the nFET; maintaining a temperature after the depositing the cap layer such that no metal atoms from the cap layer diffuse to the interlayer; depositing a pFET work function setting metal over the cap layer; and removing the cap layer and the pFET work function setting metal from the nFET.
