A first insulation film is formed on a semiconductor substrate. A first gate electrode is formed on the first insulation film. A second insulation film is formed on an upper surface and a side surface of the first gate electrode. A second gate electrode is formed on the second insulation film. The entirety of that part of the second gate electrode, which is located above the second insulation film formed on the upper surface of the first gate electrode, is a silicide layer. At least a portion of that part of the second gate electrode, which is located on the side surface of the first gate electrode, is a silicon layer.
