After an upper poly layer is formed on the resultant structure including the gate poly layer, the upper poly layer is selectively removed to leave the upper poly layer only in a region where a gate electrode is to be formed. After an oxide layer is formed on the resultant structure including the patterned upper poly layer, a poly etch process using selectivity of the oxide layer and the poly layer is performed to lease the oxide layer on the edge of the gate electrode formation region. An etch process for a gate poly layer is performed on the resultant structure to form the gate electrode that has a protrusion on its upper edge and a concave type in its center. After a nitride layer(106) is formed on the resultant structure including the gate electrode, an etch process for a nitride layer is performed to form a gate electrode sidewall made of the nitride layer. After a silicide formation source is deposited on the resultant structure, an annealing process is performed to form silicide(107) in a region exposed to the surface.
