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

摘要:
A semiconductor device having a gate with a negative slope and a method of manufacturing the same. A poly-SiGe layer with a Ge density profile which decreases linearly from the bottom of the gate toward the top of the gate is formed and a poly-SiGe gate having a negative slope is formed by patterning the poly-SiGe layer. It is possible to form a gate whose bottom is shorter than its top defined by photolithography by taking advantage of the variation of etching characteristics with Ge density when patterning. Accordingly, the gate is compact enough for a short channel device and gate resistance can be reduced.
