Patent ID: 10068876

Abstract:
A semiconductor devise includes a first substrate and a second substrate which are bonded each other. A first substrate includes an insulating first surface film as an uppermost layer, a first electrode and an insulating second surface film respectively formed inside a plurality of openings in the first surface film, and a first seal ring. A second substrate includes an insulating third surface film as an uppermost layer, and a second electrode, an insulating fourth surface film respectively formed inside a plurality of openings in the third surface film, and a second seal ring. The first electrode and the second electrode are directly bonded together. The first surface film and the third surface film are directly bonded together. The second surface film and the fourth surface film are directly bonded together. A seal ring formed of the first seal ring, the second surface film, the fourth surface film, and the second seal ring is continuous between the first substrate and the second substrate.
