    摘要: Example embodiments relate to a method of forming a germanium (Ge) silicide layer, a semiconductor device including the Ge silicide layer, and a method of manufacturing the semiconductor device. A method of forming a Ge silicide layer according to example embodiments may include forming a metal layer including vanadium (V) on a silicon germanium (SiGe) layer. The metal layer may have a multiple-layer structure and may further include at least one of platinum (Pt) and nickel (Ni). The metal layer may be annealed to form the germanium silicide layer. The annealing may be performed using a laser spike annealing (LSA) method.

    摘要: CMOS integrated circuit devices include an electrically insulating layer and an unstrained silicon active layer on the electrically insulating layer. An insulated gate electrode is also provided on a surface of the unstrained silicon active layer. A Si1-xGex layer is also disposed between the electrically insulating layer and the unstrained silicon active layer. The Si1-xGex layer forms a first junction with the unstrained silicon active layer and has a graded concentration of Ge therein that decreases monotonically in a first direction extending from a peak level towards the surface of the unstrained silicon active layer. The peak Ge concentration level is greater than x=0.15 and the concentration of Ge in the Si1-xGex layer varies from the peak level to a level less than about x=0.1 at the first junction. The concentration of Ge at the first junction may be abrupt. More preferably, the concentration of Ge in the Si1-xGex layer varies from the peak level where 0.2
