Abstract:
A semiconductor device includes first source/drain regions disposed at both sides of a first gate structure and including dopants of a first conductivity type, counter regions being in contact with upper portions of the first source/drain regions and under both end portions of the first gate structure, and first halo regions in contact with bottom surfaces of the first source/drain regions. The counter regions include dopants of a second conductivity type that is different from the first conductivity type. The first halo regions include dopants of the second conductivity type.

Claim (Index 5):
A method of fabricating a semiconductor device, the method comprising:\n forming a device isolation pattern on a substrate, the device isolation pattern defining a first active pattern of a first region of the substrate and a second active pattern of a second region of the substrate; forming a first preliminary gate structure on the first region, the first preliminary gate structure intersecting the first active pattern and the device isolation pattern; forming a second preliminary gate structure on the second region, the second preliminary gate structure intersecting the second active pattern and the device isolation pattern; forming counter regions by implanting dopant ions of a first conductivity type into the first active pattern at both sides of the first preliminary gate structure; forming LDD regions by implanting dopant ions of a second conductivity type opposite to the first conductivity type into the second active pattern at both sides of the second preliminary gate structure; etching the first active pattern at both sides of the first preliminary gate structure and the second active pattern at both sides of the second preliminary gate structure to form first recess regions in the first active pattern and second recess regions in the second active pattern; and forming first source/drain regions in the first recess regions and second source/drain regions in the second recess regions, the first and second source/drain regions including dopants of the second conductivity type.
