    摘要: In a method of manufacturing a semiconductor device, a recess is formed in an active region of a substrate. A gate insulation layer is formed in the first recess. A barrier layer is formed on the gate insulation layer. A preliminary nucleation layer having a first resistance is formed on the barrier layer. The preliminary nucleation layer is converted into a nucleation layer having a second resistance substantially smaller than the first resistance. A conductive layer is formed on the nucleation layer. The conductive layer, the nucleation layer, the barrier layer and the gate insulation layer are partially etched to form a buried gate structure including a gate insulation layer pattern, a barrier layer pattern, a nucleation layer pattern and a conductive layer pattern.

    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.
