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.

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： In a gate structure and a method of forming the same, a first conductive pattern is formed on a substrate and comprises a metal-containing material. A second conductive pattern is formed on the first conductive pattern, and the second conductive pattern comprises metal and silicon. A third conductive pattern is formed on the second conductive pattern, and the third conductive pattern comprises polysilicon. A gate conductive pattern of an n-type metal-oxide semiconductor (NMOS) transistor, a p-type MOS (PMOS) transistor and a complementary MOS (CMOS) transistor includes the gate structure. The second conductive pattern is interposed between the first and third conductive patterns and the third conductive pattern is prevented from making direct contact with the first conductive pattern, so that polysilicon in the third conductive pattern is sufficiently prevented from being chemically reacted with the metal in the first conductive pattern in advance, thereby improving electrical characteristics of the transistor.
