ABSTRACT:
The semiconductor integrated circuit comprises a semiconductor substrate having a circuit region, a pad formed at the surface of the semiconductor substrate and forming a PN junction with the semiconductor substrate, and first and second electrodes. Each electrode contacts the semiconductor region such that the contacting regions of the electrodes face each other with a ring shaped region between.
