Patent ID: 8286853

Claim:
A bonding apparatus for bonding individual substrates having metallic bonding portions, comprising: a thermal treating unit including a first thermal treating plate configured to support and thermally process a superimposed substrate obtained by superimposing the individual substrates with the bonding portions thereof kept in alignment with each other and a first depressurizing mechanism configured to depressurize the atmosphere within the thermal treating unit to a specified degree of vacuum; and a bonding unit including a second thermal treating plate configured to support and thermally process the superimposed substrate processed in the thermal treating unit, a pressing mechanism configured to press the superimposed substrate against the second thermal treating plate, and a second depressurizing mechanism configured to depressurize the atmosphere within the bonding unit to a specified degree of vacuum, wherein the thermal treating unit is air-tightly connected to the bonding unit, and the first thermal treating plate includes a cooling mechanism configured to cool the superimposed substrate placed on the first thermal treating plate.
