  • Patent number: 6962007
    Abstract: A device for drying substrates which stores a plurality of substrate (1) and which comprises a processing container (3) to which cleaning fluid (2) after cleaning the substrates (1) is drained and an injection nozzle (5) for injecting drying fluid located at the terminating part of a feed pipe (4) through which liquid drying fluid is supplied, whereby an exhaust equipment is eliminated or simplified, and the drying fluid is fed smoothly.

  • Patent number: 6904702
    Abstract: The substrate drying apparatus has a substrate processing vessel 1, a substrate supporting section for supporting plural substrates 2 in a standing condition and lined up condition in the interior of the substrate processing vessel 1, fluid reservoir section 3 for drying provided at an upward predetermined position of the substrate processing vessel 1, a first inert gas supplying section 4 for blowing inert gas against the drying fluid 6 pooled in the fluid reservoir section 3 for drying so as to generate droplet of the drying fluid, and for guiding the droplet towards the center of the substrate processing vessel 1, and a second inert gas supplying section 5 for supplying inert gas vertically and downwardly so as to supply the generated droplet of the drying fluid towards the substrates 2, consequently safety is improved without providing special safety device, and sufficient amount of drying fluid is supplied to the dipping boundary face of the substrate and the cleaning liquid.

  • Patent number: 6589386
    Abstract: A device for processing a substrate comprises a processing vessel (1), an outer vessel (2) for surrounding the processing vessel (1) which outer vessel (2) can be sealed, a first supporting member (4) for bringing the substrate (3) into and out from the processing vessel (1) which first supporting member (4) supports the substrate (3) in a standing manner, and a second supporting member (5) for transferring the substrate (3) between the first supporting member (4) which second supporting member (5) is movable up and down within the processing vessel (1). The device processes the entire surface of the substrate (3) uniformly and prevents varying in processing from occurrence.
