Abstract

A capacitor having a first electrode, a thin insulator formed on said first electrode and a second electrode formed on said insulator wherein said first and second electrodes are composed of semiconductors that are of complementary conductivity type. Therefore, the current that flows through the capacitor insulator is efficiently suppressed while the thickness of the insulator is decreased, making it possible to realize a capacitor of a small area yet having a large capacitance.
