摘要： In a method of manufacturing a transistor, a gate structure is formed on a substrate including silicon. An upper portion of the substrate adjacent to the gate structure is etched to form a first recess in the substrate. A preliminary first epitaxial layer including silicon-germanium is formed in the first recess. An upper portion of the preliminary first epitaxial layer is etched to form a second recess on the preliminary first epitaxial layer. In addition, a portion of the preliminary first epitaxial layer adjacent to the second recess is etched to thereby transform the preliminary first epitaxial layer into a first epitaxial layer. A second epitaxial layer including silicon-germanium is formed in the second recess located on the first epitaxial layer.
