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 1):
A method of fabricating a semiconductor device, the method comprising:\n forming a device isolation pattern on a substrate including an active pattern protruding from the substrate, the device isolation pattern exposing an upper portion of the active pattern; forming a preliminary gate structure on the substrate, the preliminary gate structure intersecting the active pattern and the device isolation pattern; forming halo regions having a first depth in the active pattern, the forming the halo regions including implanting first dopant ions of a first conductivity type into the active pattern at both sides of the preliminary gate structure; forming counter regions having a second depth smaller than the first depth in the active pattern, the forming the counter regions including implanting second dopant ions of the first conductivity type into the active pattern at both sides of the preliminary gate structure; etching the active pattern at both sides of the preliminary gate structure to form recess regions; and forming source/drain regions in the recess regions using an epitaxial growth process, the source/drain regions including dopants of a second conductivity type opposite to the first conductivity type.
