Abstract:
1. A substrate processing apparatus comprising: a plurality of blocks of heat treatment apparatus groups each comprised of heat treatment apparatuses each of which treats a processing target substrate at a predetermined temperature and which are stacked in a vertical direction as a vertical block, or which are disposed in a horizontal direction as a horizontal block, a temperature adjustment mechanism that is provided in each of the heat treatment apparatuses for adjusting a temperature of the processing target substrate; a heating mechanism that performs heating processing on the processing target substrate; a moving mechanism that moves the temperature adjustment mechanism forward or backward with respect to the heating mechanism; an exhaust mechanism that is provided on a side opposite to an arrangement of the temperature adjustment mechanism of the heating mechanism and that exhausts a gas from the heat treatment apparatus while substantially introducing an atmosphere inside the heat treatment apparatus or outside the heat treatment apparatus to the inside of the heat treatment apparatus; a plurality of supply ports that supplies a temperature adjustment liquid to each of the temperature adjustment mechanisms of the heat treatment apparatuses for each vertical block, each horizontal block, every predetermined number of the heat treatment apparatuses in the vertical block, or every predetermined number of the heat treatment apparatuses in the horizontal block; a plurality of recovery ports that collects the liquid supplied to the temperature adjustment mechanisms of the heat treatment apparatuses for each vertical block, each horizontal block, every predetermined number of the heat treatment apparatuses in the vertical block, or every predetermined number of the heat treatment apparatuses in the horizontal block; and a control mechanism that recognizes temperature information of the liquid recovered in each of the plurality of recovery ports, said control mechanism being arranged such that when the temperature of the cooling liquid recovered for each of the heat treatment apparatus blocks or every plurality of the heat treatment apparatus in the heat treatment apparatus blocks is higher than the predetermined temperature, the cooling liquid set for a predetermined temperature for each of the heat treatment apparatus blocks or every plurality of the heat treatment apparatuses in the heat treatment apparatus blocks is supplied from another supply line.
