Patent ID: 8899289

Claim:
A joint apparatus comprising a first holding unit that suction-holds a processing target substrate and a second holding unit that is arranged to face the first holding unit and suction-holds a supporting substrate and joining the processing target substrate and the supporting substrate together by pressing the second holding unit toward the first holding unit while heating the substrates by heating mechanisms of the holding units, said apparatus comprising: a preheating unit that preheats at least the processing target substrate before the processing target substrate is suction-held on said first holding unit; a raising and lowering pin that is provided below said first holding unit, penetrates said first holding unit to freely rise and lower, and supports the processing target substrate, wherein said preheating unit is said first holding unit, and wherein the preheating on the processing target substrate is performed by heating the processing target substrate by the heating mechanism of said first holding unit with the processing target substrate disposed above said first holding unit by said raising and lowering pin.
