Abstract:
Generally, the present disclosure provides example embodiments relating to formation of a gate structure of a device, such as in a replacement gate process, and the device formed thereby. In an example method, a gate dielectric layer is formed over an active area on a substrate. A dummy layer that contains a passivating species (such as fluorine) is formed over the gate dielectric layer. A thermal process is performed to drive the passivating species from the dummy layer into the gate dielectric layer. The dummy layer is removed. A metal gate electrode is formed over the gate dielectric layer. The gate dielectric layer includes the passivating species before the metal gate electrode is formed.

Claim (Index 15):
A structure comprising:\n an interfacial layer over a channel region; a fluorinated gate dielectric over the interfacial layer; a capping layer over the fluorinated gate dielectric; residual metal over the capping layer; one or more work function layers over the residual metal and the capping layer; and a gate fill over the one or more work function layers, wherein the fluorinated gate dielectric has a gradient fluorine concentration decreasing from an interface between the fluorinated gate dielectric and the capping layer toward the interfacial layer.
