Abstract:
A semiconductor device, comprising:a semiconductor substrate; a barrier flint in a field region of the semiconductor substrate; first and second conductivity-type well regions in the semiconductor substrate and divided by the barrier film in a surface of the semiconductor substrate; a gate insulating film on an entire surface of the semiconductor substrate; a gate electrode on a region of the gate insulating film; a lightly-doped first conductivity-type impurity region formed in the second conductivity-type well region at a first side of the gate electrode; a lightly-doped second conductivity-the impurity region formed in the conductivity-type well region at a second side of the gate electrode; a conductive pattern contacting the lightly-doped first and second conductivity-type impurity regions and having a constant distance from the gate electrode; an insulating film formed on the semiconductor substrate exposing upper portions of the gate electrode and the conductive pattern; and heavily-doped first and second conductivity-type impurity regions formed on the lightly-doped first and second conductivity-type impurity regions below the conductive pattern, wherein an upper surface of the gate electrode is level with an upper surface of the conductive pattern.
