Abstract
A complementary metal-oxide-semiconductor (CMOS) integrated circuit structure, and method of fabricating the same according to a replacement metal gate process. P-channel and n-channel MOS transistors are formed with high-k gate dielectric material that differ from one another in composition or thickness, and with interface dielectric material that differ from one another in composition or thickness. The described replacement gate process enables construction so that neither of the p-channel or n-channel transistor gate structures includes the metal gate material from the other transistor, thus facilitating reliable filling of the gate structures with fill metal.
