Patent ID: 7290948

Claim:
A substrate processing apparatus having at least one of each of a developing processing apparatus that supplies a developing solution as a processing solution to a non-processed substrate to process and a resist coating processing apparatus that supplies a resist solution as a processing solution to the non-processed substrate, and a transfer mechanism configured to enable the non-processed substrate to be transferred to the developing processing apparatus and/or the resist coating processing apparatus, wherein each of the developing processing apparatus and the resist coating processing apparatus has a cup mechanism that processes the non-processed substrate therein, a gas supply mechanism that supplies a gas with at least adjusted temperature and moisture from an upper position of the cup mechanism in the direction of the cup mechanism, and an exhaust mechanism configured to substantially enable the gas from the gas supply mechanism to be exhausted from both an internal side and an external side of the cup mechanism, and enabling the processing solution to be collected from the internal side of the cup mechanism thereof, only the developing processing apparatus is configured to substantially enable the gas to be collected from the external side of the cup mechanism thereof, only the cup mechanism of the developing processing apparatus is configured to be substantially movable upward and downward, and substantially enabling the processing solution to be supplied therein, and respective pressures inside the developing processing apparatus and the resist coating processing apparatus are set at atmosphere pressures higher than a pressure of an atmosphere where the transfer mechanism is disposed.
