    摘要: A method of fabricating a semiconductor device includes forming an interlayer dielectric on a substrate, the interlayer dielectric including first and second openings respectively disposed in first and second regions formed separately in the substrate; fondling a first conductive layer filling the first and second openings; etching the first conductive layer such that a bottom surface of the first opening is exposed and a portion of the first conductive layer in the second opening remains; and forming a second conductive layer filling the first opening and a portion of the second opening.

    摘要: In an etchant for etching a capping layer having etching selectivity with respect to a dielectric layer, the capping layer changes compositions of the dielectric layer, to thereby control a threshold voltage of a gate electrode including the dielectric layer. The etchant includes about 0.01 to 3 percent by weight of an acid, about 10 to 40 percent by weight of a fluoride salt and a solvent. Accordingly, the dielectric layer is prevented from being damaged by the etching process for removing the capping layer and the electric characteristics of the gate electrode are improved.

    摘要: The method involves providing a semiconductor substrate comprising first and second regions in which different conductive metal-oxide semiconductor (MOS) transistors are to be formed. A gate dielectric layer above the semiconductor substrate sequentially forming a first metallic conductive layer and a second metallic conductive layer on and above the gate dielectric layer; covering the second region with a mask, and performing ion plantation of a first material into the first metallic conductive layer of the first region. Removing the second metallic conductive layer of the first region and forming a first gate electrode of the first region and a second gate electrode of the second region by patterning the gate dielectric layer and the first metallic conductive layer of the first region, and the gate dielectric layer, the first metallic conductive layer, and the second metallic conductive layer of the second region. The first and second regions of the semiconductor substrate having different work functions because the gate electrodes of the first and second regions have different thicknesses and at least one of the first and second gate electrodes include impurities.
