Abstract
A package includes a plurality of bonded substrates including a first substrate and a second substrate defining a cavity therebetween. A first bonding film resides on opposed surfaces of the first substrate and the second substrate so as to surround the cavity. The second bonding film surrounds the cavity and resides on the opposed surfaces of the first and second substrates adjacent to the first bonding film. The second bonding film has a bonding force stronger than the first bonding film and the ionization resistance of the first bonding film is greater than the ionization resistance of the second bonding film.
