  • Publication number: 20180254201
    Abstract: A single-wafer substrate processing device is provided which does not spill a processing liquid and the vapors thereof to an exterior when directly supplying the process liquid to a surface of a substrate to process the substrate and which prevents the process liquid and the vapors, etc., thereof to adhere a ceiling, etc., of a housing. The device includes a housing 1, holding means 4 that holds, in the housing 1, a substrate 3 subjected to an eliminating process of adhering materials on a processing surface with a processing surface 3a being directed to the bottom 1b of the housing, supply means that supplies a process liquid to the processing surface 3a of the substrate 3 held by the holding means 4, an inlet 1a for taking in a gaseous body in the housing 1, and an outlet 1c for evacuating from the housing the vapors of the process liquid in the housing 1 together with the gaseous body taken in from the inlet 1a.

  • Patent number: 6637445
    Abstract: A substrate processing unit 10 capable of restraining contaminants such as particles, watermarks and the like from being adhered to a substrate such as a semiconductor wafer and the like, wherein the substrate processing unit 10 comprises a processing bath 11 for accommodating the substrates (e.g., wafer W) to be processed, a processing fluid introduction pipe 21 for supplying processing fluid (e.g., purified water J) to the processing bath 11, a vapor generating bath 61 for accommodating an organic solvent S (e.g., IPA fluid), a processing fluid discharge section 30 for discharging processing fluid from the processing bath 11, and a solvent heating unit 62 for heating the organic solvent S inside the vapor generating bath 61, wherein the vapor generating bath 61 introduces vapor generated from the organic solvent S to the inside of the processing bath 11, and the solvent heating unit 62 heats the organic solvent S inside the vapor generating bath 61 at a temperature in the range of 50° C.
