Abstract: A substrate processing apparatus is equipped with a holder having, on an attraction surface configured to attract a substrate, a circular central region and an annular outer region disposed outside the central region. The holder includes a first attracting pressure generator configured to generate an attracting pressure in the central region to attract the substrate to the holder; a second attracting pressure generator configured to generate an attracting pressure in the outer region to attract the substrate to the holder; and an external force applier configured to apply an external force to the substrate in the outer region in a direction in which the substrate becomes farther from the holder.

Abstract: A bonding apparatus includes a holder; a pressing member; and a curvature adjuster. The holder is configured to attract and hold a substrate to be bonded. The pressing member is configured to come into contact with a central portion of the substrate attracted to and held by the holder and press the substrate to allow the central portion of the substrate to be protruded. The curvature adjuster is configured to adjust a curvature of the substrate pressed by the pressing member.

Abstract: A bonding apparatus includes a first holder, a first transforming device, a second holder, a second transforming device, a suction device and a control device. The first holder attracts and holds a first substrate from above. The first transforming device transforms the first substrate held by the first holder such that a central portion of the first substrate is protruded downwards. The second holder is provided under the first holder, and attracts and holds a second substrate, which is to be bonded to the first substrate, from below. The second transforming device transforms the second substrate held by the second holder such that a central portion of the second substrate is protruded upwards. The suction device generates different attracting forces in multiple division regions included in an attraction region of the second substrate. The control device controls the suction device.

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.

Abstract: A substrate processing apparatus is equipped with a holder having, on an attraction surface configured to attract a substrate, a circular central region and an annular outer region disposed outside the central region. The substrate processing apparatus includes an attracting pressure generator configured to generate an attracting pressure in the central region and each of multiple zones separated along a circumferential direction of the outer region individually; a transforming device configured to transform the central region relative to an outer edge of the holder. A controller controls: attracting the substrate to the attraction surface, based on a bending state of the substrate, by generating the attracting pressure in at least some of the multiple zones of the outer region; and transforming, after the attracting of the substrate, the attraction surface while carrying on the attracting of the substrate.
