Abstract:
1. A joint apparatus joining substrates having metal joint portions, comprising: a pre-thermal processing unit comprising a first thermal processing plate mounting and thermally processing a superposed substrate in which the substrates are superposed on each other with the joint portions in contact with each other, and a first pressure reducing mechanism reducing a pressure of an atmosphere therein down to a predetermined degree of vacuum; a joint unit comprising a second thermal processing plate mounting and thermally processing the superposed substrate processed in said 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 reducing a pressure of an atmosphere therein down to a predetermined degree of vacuum; and a post-thermal processing unit comprising a third thermal processing plate mounting and thermally processing the superposed substrate processed in said joint unit, and a third pressure reducing mechanism reducing a pressure of an atmosphere therein down to a predetermined degree of vacuum, wherein each of said pre-thermal processing unit and said post-thermal processing unit is hermetically connected to said joint unit.
