A semiconductor device having a recess channel structure includes a semiconductor substrate having a recess formed in a gate forming area in an active area; an insulation layer formed in the semiconductor substrate so as to define the active area and formed so as to apply a tensile stress in a channel width direction; a stressor formed in a surface of the insulation layer and formed so as to apply a compressive stress in a channel height direction; a gate formed over the recess in the active area; and source/drain areas formed in a surface of the active area at both side of the gate.
