Similarly, when the second object to be processed 702 needs to be processed, the first heating stage 401 is taken out of the processing chamber 200, and the second object to be processed 702 is placed on the second heating stage 402 to be heated and irradiated with ultraviolet light. That is, the process chamber 200 can process only the first object to be processed 701 or the second object to be processed 702 alone, and cannot process the first object to be processed 701 or the second object to be processed 702 at the same time.

Of course, as an alternative embodiment, the first heating stage 401 and the second heating stage 402 may be disposed side by side, so that the first heating stage 401 and the second heating stage 402 do not have an overlapping region on the optical path of the ultraviolet light, the ultraviolet light may be simultaneously irradiated to the first object to be processed 701 and the second object to be processed 702, and the process chamber 200 may simultaneously process the first object to be processed 701 and the second object to be processed 702.
