Abstract

A contact plug is formed in a semiconductor device having a silicon substrate having a gate electrode, a junction area and an insulating interlayer. A contact hole is formed to expose the junction area. A plasma process is carried out with respect to a resultant substrate, thereby removing natural oxides created on an exposed surface of the junction area. A first silicon layer is deposited on the contact hole and on the insulating interlayer. A heat-treatment process is carried out with respect to the first silicon layer so as to grow the amorphous silicon into the epitaxial silicon. A second silicon layer is deposited on the first silicon layer.
