Abstract: Aspects of the present invention relate to approaches for forming a semiconductor device such as a field-effect-transistor (FET) having a metal gate with improved performance. A metal gate is formed on a substrate in the semiconductor device. Further processing can result in unwanted oxidation in the metal that forms the metal gate. A reducing agent can be used to de-oxidize the metal that forms the metal gate, leaving a substantially non-oxidized surface.

Abstract: A method of fabricating an integrated circuit includes the steps of providing a semiconductor substrate having formed thereon a sacrificial silicon oxide layer, an interlayer dielectric layer formed over the sacrificial silicon oxide layer, and a dummy gate structure formed over the sacrificial silicon oxide layer and within the interlayer dielectric layer, removing the dummy gate structure to form an opening within the interlayer dielectric layer, and removing the sacrificial silicon oxide layer within the opening to expose the semiconductor substrate within the opening. The method further includes the steps of thermally forming an oxide layer on the exposed semiconductor substrate within the opening, subjecting the thermally formed oxide layer to a decoupled plasma oxidation treatment, and etching the thermally formed oxide layer using a self-saturated wet etch chemistry. Still further, the method includes depositing a high-k dielectric over the thermally formed oxide layer within the opening.

Abstract: One method disclosed herein includes, among other things, forming a process layer on a substrate. A patterned mask layer is formed above the process layer. The patterned mask layer includes first openings exposing portions of the process layer. A carbon-containing silicon dioxide layer is formed above the patterned mask layer and in the first openings. The carbon-containing silicon dioxide layer is planarized to remove portions extending outside the first openings and generate a plurality of mask elements from remaining portions of the carbon-containing silicon dioxide layer. The patterned mask layer is removed. The process layer is etched using the mask elements as an etch mask.
