Claim Text:
1. A joining device for joining substrates with an intermolecular force, comprising: a first holding unit configured to hold a first substrate on a lower surface thereof, the first holding unit including a plurality of first pins which make contact with the first substrate when the first substrate is held by the first holding unit; a second holding unit installed below the first holding unit and configured to hold a second substrate on an upper surface thereof, the second holding unit including a plurality of second pins which make contact with the second substrate when the second substrate is held by the second holding unit; and a temperature adjustment mechanism configured to adjust a temperature of the first substrate before the first substrate is held in the first holding unit to a first predetermined temperature and a temperature of the second substrate before the second substrate is held in the second holding unit to a second predetermined temperature, the temperature of the second substrate being adjusted independently from adjusting the temperature of the first substrate so as to suppress the first substrate and the second substrate from being joined in a misaligned state.
