Patent ID: 8247876

Claim:
A semiconductor device comprising: an element formed on a substrate in a chip region; a plurality of dielectric films formed on the substrate; a first seal ring and a second seal ring provided so as to pass through the plurality of dielectric films and surround the chip region; a protection film formed on a first dielectric film which is the uppermost film in the plurality of dielectric films; a first opening provided in the protection film and formed on the first seal ring; and a cap layer arranged in the first opening and in contact with the first seal ring, wherein the second seal ring is formed closer to the chip region than the first seal ring, and all of an upper surface of the second seal ring is covered by the protection film, and on a plane in which the cap layer is in contact with the first seal ring, an end of the cap layer closer to a scribe region is located closer to the scribe region than the first seal ring.
