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 11):
A substrate processing method using a substrate processing apparatus, wherein\n the substrate processing apparatus includes a processing unit that includes a processing liquid nozzle that supplies a processing liquid to a substrate, and a plurality of tanks that include a supply tank, an adjustment tank and a collection tank, the substrate processing method comprising performing in parallel a supply operation for supplying the processing liquid from the supply tank to the processing liquid nozzle, a collection operation for collecting the processing liquid from the processing unit to the collection tank, and an adjustment operation for adjusting concentration of the processing liquid stored in the adjustment tank, the performing in parallel the supply operation, the collection operation and the adjustment operation including: changing a path of the processing liquid such that the collection tank is changed to the adjustment tank after the collection operation is finished; changing the path of the processing liquid such that the adjustment tank is changed to the supply tank and the adjusted processing liquid is supplied to the processing unit after the adjustment operation is finished; and changing the path of the processing liquid such that the supply tank is changed to the collection tank after the supply operation is finished, wherein the plurality of tanks include first, second and third tanks, any one of the first, second and third tanks is set as the supply tank, another one of the first, second and third tanks is set as the collection tank, yet another one of the first, second and third tanks is set as the adjustment tank, the supply operation is performed by supplying the processing liquid to the processing liquid nozzle from the first, second or third tank set as the supply tank, the collection operation is performed by collecting the processing liquid from the processing unit selectively to the first, second or third tank set as the collection tank, and the adjustment operation is performed by adjusting concentration of the processing liquid stored in the first, second or third tank set as the adjustment tank, and the performing in parallel the supply operation, the collection operation and the adjustment operation further includes: sequentially performing the supply operation from the first tank to the processing liquid nozzle, the supply operation from the third tank to the processing liquid nozzle, and the supply operation from the second tank to the processing liquid nozzle; sequentially performing the collection operation from the processing unit to the second tank, the collection operation from the processing unit to the first tank, and the collection operation from the processing unit to the third tank; and sequentially performing the adjustment operation in the third tank, the adjustment operation in the second tank, and the adjustment operation in the first tank.
