Abstract:
Gate structures and methods of forming the gate structures are described. In some embodiments, a method includes forming source/drain regions in a substrate, and forming a gate structure between the source/drain regions. The gate structure includes a gate dielectric layer over the substrate, a work function tuning layer over the gate dielectric layer, a metal-containing compound over the work function tuning layer, and a metal over the metal-containing compound, wherein the metal-containing compound comprises the metal as an element of the compound.

Claim (Index 15):
A structure comprising:\n a gate structure on a substrate, the gate structure comprising:\n a gate dielectric layer over the substrate; \n a titanium nitride (TiN) layer over the gate dielectric layer; \n a tantalum nitride (TaN) layer over the TiN layer; \n a work function tuning layer over the TaN layer, the work function tuning layer comprising TiN; \n a tungsten-containing compound over the work function tuning layer; \n a tungsten layer over the tungsten-containing compound; and \n a dielectric cap over the tungsten layer, the dielectric cap being in physical contact with the gate dielectric layer, the TiN layer, the TaN layer, the work function tuning layer, the tungsten-containing compound, and the tungsten layer; and \n a spacer on a sidewall of the gate structure and a sidewall of the dielectric cap, the spacer being in physical contact with the dielectric cap.
