Abstract
Disclosed is a method for forming a gate electrode of a semiconductor device, the method comprises the steps of: stacking a gate oxide film, a doped first silicon film, a diffusion preventing film, a metal film having a high melting point and a mask insulating film on a semiconductor substrate; forming a gate electrode by patterning a resultant stack structure; forming a second silicon film on an entire surface of a resultant structure; forming an oxidation preventing film on an entire surface of a resultant structure; forming a spacer on a side wall of the gate electrode by anisotrophically etching the oxidation preventing film and the second silicon film; and forming a gate reoxide film on the semiconductor substrate by oxidizing the semiconductor substrate.
