The second step is to form an over-etched portion having a constant step via a gate forming portion of the first photosensitive film in a gate oxide film. The third step is to remove the first photosensitive film and then deposit a poly-gate layer(50) on a resultant, which the first photosensitive film is removed, and to laminate a poly gate layer uniformly. The fourth step is to deposit the second photosensitive film(60) on an area for a gate electrode to be formed of the poly-gate layer. The fifth step is to etch the poly-gate layer and the gate oxide film using the second photosensitive film as a mask. The sixth step is to implant ions on the semiconductor substrate of the side portion of the gate electrode to form source and drain areas.
