    摘要: A semiconductor device comprises a substrate, a channel region, and a gate formed in association with the channel region. In one exemplary embodiment, the gate comprises a first material that is formed void free on an interior surface of a gate trench of the gate. A width of the gate trench comprises between about 8 nm and about 65 nm. The gate comprises a transition metal alloyed with carbon, aluminum or nitrogen, or combinations thereof, to form a carbide, a nitride, or a carbo-nitride, or combinations thereof, of the transition metal. In another exemplary embodiment, the gate further comprises a second material formed void free on an interior surface of the first material and comprises a transition metal alloyed with carbon, aluminum or nitrogen, or combinations thereof, to form a carbide, a nitride, or a carbo-nitride, or combinations thereof, of the transition metal.

    摘要: An exemplary embodiment of a method for forming a gate for a planar-type or a finFET-type transistor comprises forming a gate trench that includes an interior surface. A first work-function metal is formed on the interior surface of the gate trench, and a low-resistivity material is deposited on the first work-function metal using a chemical vapor deposition (CVD) technique, or an atomic layer deposition (ALD) technique, or combinations thereof. Another exemplary embodiment provides that a second work-function metal is formed on the first work-function metal, and then the low-resistivity material is deposited on the first work-function metal using a chemical vapor deposition (CVD) technique, or an atomic layer deposition (ALD) technique, or combinations thereof.
