摘要:
A method for making a semiconductor device is described. That method comprises forming a first dielectric layer on a substrate, then forming a trench within the first dielectric layer. After forming a second dielectric layer on the substrate, a first metal layer is formed within the trench on a first part of the second dielectric layer. A second metal layer is then formed on the first metal layer and on a second part of the second dielectric layer.

A method for making a titanium carbide layer is described. That method comprises alternately introducing a carbon containing precursor and a titanium containing precursor into a chemical vapor deposition reactor, while a substrate is maintained at a selected temperature. The reactor is operated for a sufficient time, and pulse times are selected for the carbon containing precursor and the titanium containing precursor, to form a titanium carbide layer of a desired thickness and workfunction on the substrate.

A method for making a semiconductor device is described. That method comprises forming a dielectric layer on a substrate, forming a trench within the dielectric layer, and forming a high-k gate dielectric layer within the trench. After forming a first metal layer on the high-k gate dielectric layer, a second metal layer is formed on the first metal layer. At least part of the second metal layer is removed from above the dielectric layer using a polishing step, and additional material is removed from above the dielectric layer using an etch step.

A metal gate transistor may include a metal layer over a high dielectric constant dielectric layer. The dielectric layer abstracts electronegativity from said metal layer, altering its workfunction. The workfunction of the metal layer may be set to compensate for the dielectric layer abstraction.
