Abstract:
A disk bonding apparatus for bonding a first substrate and a second substrate, the apparatus comprising:an arrangement means for arranging the first substrate and the second substrate to be opposed to each other; an arrangement means for superposing the first substrate and the second substrate with a radiation curing resin between the two substrates; a first irradiating means for serving to irradiate radioactive rays from a first side of the superposed substrates; and a second irradiating means for irradiating the substrates from a second side of the superposed substrates; and a warpage measuring mechanism for measuring amounts of warpages of the first substrate and the second substrate; and a start timing control means for suppressing warpage of the bonded substrates by shifting the irradiation start timings of the first and second irradiating means based on a result of the measurement of the warpage measuring mechanism.
