Abstract:
A semiconductor device comprising:a semiconductor substrate; a first gate electrode formed on said semiconductor substrate via a gate insulating film which is substantially wider than the first gate electrode; a second gate electrode formed on said semiconductor substrate apart from said first gate electrode via a gate insulating film which is substantially wider than the second gate electrode; a first impurity introduced area of an LDD structure composed of a low-concentration impurity area and a high-concentration impurity area, the first impurity introduced area being formed on said semiconductor substrate on one side of said first gate electrode which is not opposed to said second gate electrode, and not extending underneath the first gate electrode; a second impurity introduced area of an LDD structure composed of a low-concentration impurity area and a high-concentration impurity area, the second impurity introduced area being formed on said semiconductor substrate on one side of said second gate electrode which is not opposed to said first gate electrode, and not extending underneath the second gate electrode; a third impurity introduced area composed solely of a high-concentration impurity area, the third impurity introduced area being formed on said semiconductor substrate in the area between said first and second gate electrodes, and not extending underneath the first and second gate electrodes; and said first and second gate electrodes being connected, at one end thereof extending in the gate width direction, to a wire contact pad formed on said semiconductor substrate via an element-separating insulating film, and being connected to each other at another end thereof.
