Abstract: A method of fabricating a semiconductor device is disclosed. The method includes forming an active pattern protruding orthogonally from a substrate; forming a preliminary gate structure on the active pattern to cross the active pattern; etching the active pattern to form preliminary recess regions at both sides of the preliminary gate structure, wherein each of the preliminary recess regions is formed to define a delta region in an upper portion of the active pattern; forming a sacrificial layer on inner side surfaces and a bottom surface of the active pattern exposed by each of the preliminary recess regions; etching the delta regions and the sacrificial layer to form recess regions having a ‘U’-shaped section; and forming source/drain regions in the recess regions.

Abstract: Semiconductor devices and methods of forming the same are provided. The methods may implanting dopants into a substrate to form a preliminary impurity region and heating the substrate to convert the preliminary impurity region into an impurity region. Heating the substrate may be performed at an ambient temperature of from about 800° C. to about 950° C. for from about 20 min to about 50 min. The method may also include forming first and second trenches in the impurity region to define an active tin and forming a first isolation layer and a second isolation layer in the first and second trenches, respectively.
