    Abstract: 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

    Abstract: A method of manufacturing a non-volatile semiconductor memory device begins by forming a dielectric layer pattern having an ONO composition on a substrate. A polysilicon layer is formed on the substrate including over the dielectric layer pattern. The polysilicon layer is patterned to form a split polysilicon layer pattern that exposes part of the dielectric layer pattern. The exposed dielectric layer is etched, and then impurities are implanted into portions of the substrate using the split polysilicon layer pattern as a mask to thereby form a source region having a vertical profile in the substrate.

The semiconductor transistor includes a gate pattern formed on a semiconductor substrate and an L-shaped third spacer formed beside the gate pattern and having a horizontal protruding portion. An L-shaped fourth spacer is formed between the third spacer and the gate pattern, and between the third spacer and the substrate. A high-concentration junction area is positioned in the substrate beyond the third spacer, and a low-concentration junction area is positioned under the horizontal protruding portion of the third spacer. A medium-concentration junction area is positioned between the high- and low-concentration junction areas.
