    摘要: A method of manufacturing a gate electrode of a MOS transistor including a tungsten carbon nitride layer is disclosed. After a high dielectric layer is formed on a substrate, a source gas including tungsten amine derivative flows onto the high dielectric layer. A tungsten carbon nitride layer is formed on the high dielectric layer by decomposing the source gas. Thereafter, a gate electrode is formed by patterning the tungsten carbon nitride layer. According to the present invention, a gate electrode having a work function of over 4.9 eV is formed.

    摘要: In a semiconductor device with dual gates and a method of manufacturing the same, a dielectric layer and first and second metallic conductive layers are successively formed on the semiconductor substrate having first and second regions. The second metallic conductive layer which is formed on the first metallic conductive layer of the second region is etched to form a metal pattern. The first metallic conductive layer is etched using the metal pattern as an etching mask. A polysilicon layer is formed on the dielectric layer and the metal pattern. The first gate electrode is formed by etching portions of the polysilicon layer, the metal pattern, and the first metallic conductive layer of the first region. The second gate electrode is formed by etching a portion of the polysilicon layer formed directly on the dielectric layer of the second region.

    摘要: A semiconductor device having a dual gate is formed on a substrate having a dielectric layer. A first metallic conductive layer is formed on the dielectric layer to a first thickness, and annealed to have a reduced etching rate. A second metallic conductive layer is formed on the first metallic conductive layer to a second thickness that is greater than the first thickness. A portion of the second metallic conductive layer formed in a second area of the substrate is removed using an etching selectivity. A first gate structure having a first metallic gate including the first and the second metallic conductive layers is formed in a first area of the substrate. A second gate structure having a second metallic gate is formed in the second area. A gate dielectric layer is not exposed to an etching chemical due to the first metallic conductive layer, so its dielectric characteristics are not degraded.
