Abstract
Even when two processing furnaces are included, space can be saved by removing needed equipment. Included are: first and second furnaces that process a substrate; a heat exchanger that cools a refrigerant discharged from the first and second furnaces; an exhaust blower that sucks the refrigerant discharged from the heat exchanger and sends out the refrigerant to a downstream side; first and second flow paths that connect the first and second furnaces, the heat exchanger, and the exhaust blower to each other such that the refrigerant can flow therethrough; first and second dampers having variable opening degrees disposed upstream from the heat exchanger in the first and second flow paths, respectively; and a controller that controls heating and cooling of the first and second furnaces. The first and second flow paths merge together in at least a part of each of the first and second flow paths.
