Patent ID: 8703592

Claim:
A method of forming a semiconductor device, comprising: preparing a semiconductor substrate including a first region and a second region adjacent the first region; forming a sacrificial pattern covering the second region and exposing the first region; forming a capping layer including a faceted sidewall on the exposed first region using selective epitaxial growth (SEG), the faceted sidewall being separated from the sacrificial pattern; removing the sacrificial pattern; and implanting impurity ions into the semiconductor substrate using an inclined ion implantation process, wherein the faceted sidewall is formed to an angle of intersection of about 50 to about 59 degrees with a main surface of the semiconductor substrate that is substantially coplanar with a surface of the sacrificial pattern, and wherein implanting impurity ions comprises forming a lightly doped drain (LDD) and a halo in the second region using the inclined ion implantation process at inclinations selected based on the angle of intersection of the faceted sidewall.
