Classification: CPC B  H | IPC B

Claim 10:
11. A bonding apparatus, including a first holder configured to attract and hold a first substrate; a second holder configured to attract and hold a second substrate; and a moving mechanism configured to move the first holder and the second holder relative to each other, configured to form a combined substrate by bringing the first substrate and the second substrate into contact with each other with the moving mechanism, the bonding apparatus comprising:
a heating unit configured to heat the first substrate and the second substrate or the combined substrate;
a cooling unit configured to cool the heated combined substrate; and
a controller configured to control the cooling unit,
wherein the controller controls bending of the combined substrate by controlling the cooling unit to form a temperature difference between a first main surface of the combined substrate and a second main surface of the combined substrate, the second main surface being opposite to the first main surface,
wherein the cooling unit comprises a cooling plate and an inverting unit configured to invert the combined substrate, and
wherein the controller controls the inverting unit to invert the combined substrate to allow a predetermined one of the first main surface and the second main surface to face the cooling plate, and then, place the combined substrate on the cooling plate such that the temperature difference is formed between the first main surface and the second main surface.
