    摘要: In a method of forming a metal gate in a semiconductor device, a gate insulation pattern and a dummy gate pattern are formed on a substrate. An insulation interlayer is formed on the dummy gate pattern to cover the dummy gate pattern. The insulation interlayer is polished such that a top surface of the dummy gate pattern is exposed, and the dummy gate pattern is selectively removed to form a trench on the substrate. A gate spacer is formed on an inner sidewall of the trench for determining a gate length of the metal gate. A metal is deposited to a sufficient thickness to fill the trench to form a metal layer. The metal layer is polished to remain in the trench. Accordingly, the gate length of the metal gate may be reduced no more than the resolution limit of the photolithography exposing system.

    摘要: In a method of manufacturing a semiconductor device, a preliminary metal silicide layer is selectively formed on a substrate having a transistor, the transistor having source/drain regions. A capping layer having a thermal expansion coefficient greater than that of the preliminary metal silicide layer is formed on the substrate having the preliminary metal silicide layer. The substrate is thermally treated to form a metal silicide layer, and to apply a tensile stress caused by a thermal expansion coefficient difference between the metal silicide layer and the capping layer to the source/drain regions of the transistor.
