Zusammenfassung:In a semiconductor device and related method of fabricating the same, a hard mask layer is formed over a substrate, portions of the hard mask layer and the substrate are etched to form trenches having protruding portions at sidewalls, and an insulation layer buried in the trenches is formed to form device isolation regions having protruding portions at sidewalls, wherein the device isolation regions decrease a portion of a width of active regions.
