Provided is a technique capable of improving the reliability of a semiconductor device having a slit made over a main surface of a semiconductor substrate, so as to surround each element formation region. In the technique, a second passivation film covers the side surface of an opening made to make the upper surface of a sixth-layer interconnection M6 used for bonding pads naked, and the inner walls (the side surfaces and the bottom surface) of a slit made to surround the circumference of a guard ring and made in a first passivation film, an insulating film for bonding, and an interlayer dielectric, so as to cause the bottom thereof not to penetrate through a barrier insulating film.
