CONSTITUTION: A gate electrode formation method includes sequentially stacking a gate oxide film(12), a doped polysilicon layer and a tungsten film on a semiconductor substrate(10). Then, the tungsten film is patterned by means of photography and etch process using the gate electrode as a mask, thus depositing polysilicon on the pattern structure. Next, the polysilicon film and the underlying doped polysilicon film(14') are etched to form a sidewall spacer(24') at the sidewall of the tungsten pattern(16'), while simultaneously forming a doped polysilicon film pattern below the pattern, thus defining a gate electrode(G). A thin oxide film is formed on the resulting surface in which the gate electrode is formed. A low-concentration conductive-type impurity is implanted around the substrate using the gate electrode as a mask, thus forming an LDD region(28).
