Abstract:
In a substrate processing apparatus, a phosphoric acid aqueous solution is supplied to a processor, and a liquid collection from the processor is concurrently performed. Further, a silicon concentration is adjusted, to supply an adjusted processing liquid to the processor. Thus, a phosphoric acid aqueous solution film is formed on the substrate. The liquid film is heated by a heating device. The heating device has lamp heaters in a casing made of a silica glass. The phosphoric acid aqueous solution on the substrate is irradiated with infrared rays. A nitrogen gas flowing in a gas passage formed in the casing is discharged towards a position outside an outer periphery of the substrate.

Claim (Index 1):
A substrate processing method in a substrate processing apparatus including a processing unit having a processing liquid nozzle that supplies a processing liquid to a substrate, a first tank, a second tank, a third tank, and a path switcher that switches a path of the processing liquid among the processing unit, the first tank, the second tank, and the third tank, the method comprising:\n performing a supply operation of supplying the processing liquid from the first tank to the processing liquid nozzle of the processing unit; performing a collection operation of collecting the processing liquid from the processing unit to the second tank in parallel with the supply operation; performing an adjustment operation of adjusting concentration of the processing liquid stored in the third tank in parallel with the supply operation and the collection operation by the second tank; supplying the adjusted processing liquid from the third tank to the first tank in parallel with the supply operation after the adjustment operation by the third tank is finished; performing a collection operation of collecting the processing liquid from the processing unit to the third tank in parallel with the supply operation after the adjusted processing liquid is supplied from the third tank to the first tank; performing an adjustment operation of adjusting concentration of the processing liquid stored in the second tank in parallel with the supply operation and the collection operation by the third tank; supplying the adjusted processing liquid from the second tank to the first tank in parallel with the supply operation after the adjustment operation by the second tank is finished; switching the path switcher such that the collection operation by the second tank and the collection operation by the third tank are performed alternately; and switching the path switcher such that the adjustment operation by the third tank and the supply operation to the first tank, and the adjustment operation by the second tank and the supply operation to the first tank are performed alternately.
