US Patent 7629254 Semiconductor device

Embodiments relater to a semiconductor device and a method of fabricating the same. A source/drain area may be formed by using the spacer having the dual structure of the oxide layer and nitride layer. After etching a part of the oxide layer, the salicide layer may be formed on the gate electrode and the source/drain area, and the spacer may be removed. The contact area may be ensured, so a higher degree of integration may be achieved.
