Disclosed are a semiconductor device and a method for manufacturing the same. The semiconductor device includes an isolation area formed on a semiconductor substrate to define NMOS and PMOS areas, a gate insulating layer and a gate formed on each of the NMOS and PMOS areas, a primary gate spacer formed at sides of the gate, LDD areas formed in the semiconductor substrate at sides of the gate, a secondary gate spacer formed at sides of the primary gate spacer, source and drain areas formed in the semiconductor substrate at sides of the gate of the PMOS area; and source and drain areas formed in the semiconductor substrate at sides of the gate of the NMOS area, wherein the source and drain areas of the NMOS area are deeper than the source and drain areas of the PMOS area.
