  • Publication number: 20180047699
    Abstract: Deformation of substrates after the substrates are bonded can be suppressed. A bonding apparatus includes a first holding unit configured to attract and hold a first substrate from above; a second holding unit provided under the first holding unit and configured to attract and hold a second substrate from below; and a striker configured to press a central portion of the first substrate from above and bring the first substrate into contact with the second substrate. The first holding unit is configured to attract and hold a partial region of a peripheral portion of the first substrate, and the first holding unit attracts and holds the region which intersects with a direction, among directions from the central portion of the first substrate toward the peripheral portion thereof, in which a bonding region between the first substrate and the second substrate is expanded fastest.

  • Patent number: 9741595
    Abstract: There is provided a method of bonding substrates to each other, which includes: holding a first substrate on a lower surface of a first holding part; adjusting a temperature of a second substrate by a temperature adjusting part to become higher than a temperature of the first substrate; holding the second substrate on an upper surface of a second holding part; inspecting a state of the second substrate by imaging a plurality of reference points of the second substrate with a first imaging part, measuring positions of the reference points, and comparing a measurement result with a predetermined permissible range; and pressing a central portion of the first substrate with a pressing member, bringing the central portion of the first substrate into contact with a central portion of the second substrate, and sequentially bonding the first substrate and the second substrate.
