Example embodiments of the present invention relate to methods of manufacturing a semiconductor device. Other example embodiments of the present invention relate to methods of manufacturing a semiconductor device having a gate electrode.

A native oxide layer on the exposed pad may be removed by a fourth etching process to form a capacitor contact hole. A conductive layer may be formed in the capacitor contact hole to form a capacitor.
