Abstract
In a method of manufacturing a transistor, a gate structure is formed on a substrate. First impurities are implanted into the substrate to form an impurity region at an upper portion of the substrate adjacent to the gate structure. An epitaxial layer is formed on the impurity region. An insulation layer having an opening partially exposing the epitaxial layer is formed on the substrate. Second impurities are implanted into a portion of the epitaxial layer exposed by the opening.
