  • Patent number: 7472713
    Abstract: A substrate processing apparatus includes a substrate processing part 46 for processing a substrate by a processing liquid and a processing-liquid recovery path 137 allowing of a passage of the processing liquid discharged from the substrate processing part 46. The processing-liquid recovery path 137 is provided with foreign substance removal lines 181, 182 including filters 200, 201 for removing an foreign substance from the processing liquid and cleaners 201, 211 for cleaning the filters 200, 201 respectively. With this constitution, it is possible to cancel the blocking of foreign substances in pipes etc. and also possible to lengthen the life span of the filters.

  • Patent number: 7354484
    Abstract: A cleaning processing apparatus comprises a spin chuck for holding a wafer W, an under plate being positioned to face the back surface of the wafer W with a prescribed gap provided therebetween, a support member for supporting the under plate, and a nozzle hole formed to extended through the plate member and the support member. A chemical liquid, a pure water and a gas can be supplied into a nozzle hole through opening-closing valves, and the chemical liquid and the pure water remaining inside the nozzle hole can be sucked by a sucking device. A pure water remaining inside the nozzle hole is sucked and removed by using the sucking device after the processing of the wafer W with a pure water and, then, a gas is spurted onto the back surface of the wafer W.
