Claim:
1. A substrate processing apparatus, comprising: one or more substrate processing units each configured to process a substrate with a processing fluid; a processing fluid supply unit configured to supply the processing fluid to the one or more substrate processing units; and a controller configured to control the processing fluid supply unit, wherein the processing fluid supply unit comprises: a storage tank configured to store the processing fluid therein; a heating heat exchanger configured to heat the processing fluid; and a supply path configured to supply the processing fluid to the one or more substrate processing units, and the supply path is equipped with a bypass path which bypasses the heating heat exchanger at an upstream of the one or more substrate processing units, and the processing fluid heated by the heating heat exchanger and the processing fluid supplied from the bypass path are mixed in the supply path and the mixed processing fluid is supplied to the one or more substrate processing units, wherein the processing fluid supply unit further comprises a first circulation path in which the heating heat exchanger, the supply path and a cooling heat exchanger configured to cool the processing fluid are connected with the storage tank in sequence, and the processing fluid stored in the storage tank is circulated through the first circulation path.
