Abstract:
A semiconductor device comprising:a first element formation region in which a device of a first conductivity type is formed; a second element formation region separated from said first element formation region by an element isolation region and in which a device of a second conductivity type different from said first conductivity type is formed; a first gate electrode provided on said first element formation region and containing an impurity of the first conductivity type; a second gate electrode provided on said second element formation region facing said first gate electrode and containing an impurity of the second conductivity type; a first impurity storage region containing said first conductivity type impurity, having one end connected to an end of said first gate electrode, and arranged in a direction different from the direction of arrangement of said first and second gate electrodes; and a second impurity storage region, physically connected to said first impurity storage region by a semiconductor layer, said second impurity storage region containing said second conductivity type impurity, and having one end connected to an end of said second gate electrode, having the other end electrically connected to the other end of said first impurity storage region, and arranged in a direction different from the direction of arrangement of said first and second gate electrodes, the widths of said first and second impurity storage regions are equal to the gate length of said first and second gate electrodes and the lengths of said first and second impurity storage regions are longer than said gate length.
