Patent ID: 7621310

Claim:
A bonded substrate manufacturing apparatus for bonding a first substrate and a second substrate together, the apparatus comprising: a liquid crystal dripping device for dripping liquid crystal on at least either one of the first and second substrates for bonding the first and second substrates together; a pressing device for bonding the first and second substrates with a seal material in an evacuated treatment chamber to prepare a bonded substrate, the seal material including a photo-curing adhesive; a hardening device for irradiating light to harden the seal material in the bonded substrate; a misalignment detection device for detecting misalignment between the first and second substrates in the bonded substrate after the seal material is hardened; and a controller coupled to the pressing device, the hardening device and the misalignment detection device and programmed to; instruct the pressing device to align first and second substrates that are to be bonded in a subsequent operation cycle based on misalignment detected by the misalignment detection device in a previous operation cycle; determine that a predetermined period has elapsed after the first and second substrates are bonded together; and instruct the hardening device to start hardening of the seal material when or after the predetermined period elapses after the first and second substrates are bonded together.
