Abstract:
A substrate laminating apparatus, comprising:an upper retention head configured to hold an upper substrate; a lower retention head configured to hold a lower substrate and disposed facing the upper retention head, the upper and lower retention heads configured to laminate the upper and lower substrates to interpose adhesive therebetween by allowing the lower and upper retention heads to be close to each other relatively; an elevating device configured to relatively move the upper retention head and the lower retention head in upper and lower directions; a lifting force application device configured to apply a lifting force to one of the upper retention head and the lower retention head when the upper substrate and the lower substrate are abutted against each other through the adhesive by the elevating device; and a control unit configured to control the lifting force application device to cancel a dead weight of the upper retention head with the lifting force.
