Abstract
A joint apparatus of the present invention includes: a pre-thermal processing unit including a first thermal processing plate mounting and thermally processing a superposed substrate where substrates are superposed on each other with joint portions of the substrates in contact with each other, and a first pressure reducing mechanism; a joint unit including a second thermal processing plate mounting and thermally processing the superposed substrate processed in the pre-thermal processing unit, a pressurizing mechanism pressing the superposed substrate on the second thermal processing plate toward the second thermal processing plate side, and a second pressure reducing mechanism; and a post-thermal processing unit including a third thermal processing plate mounting and thermally processing the superposed substrate processed in the joint unit, and a third pressure reducing mechanism, wherein each of the pre-thermal processing unit and the post-thermal processing unit is hermetically connected to the joint unit.
