  • Patent number: 9649577
    Abstract: Disclosed is a bubble removing method in which fine bubbles are removed from a filter to improve the performance of the filter. The bubble removing method includes a step of degassing a processing liquid supplied from a supply source to prepare a highly degassed liquid (highly degassed liquid preparation), a step of supplying the prepared highly degassed liquid at a first processing liquid from a pump device to a filter device (temporary liquid permeation), a step of supplying the highly degassed liquid at a second processing liquid flow rate higher than the first processing liquid flow rate from the pump device to the filter device (initial liquid permeation), and a step of causing the highly degassed liquid to flow from the pump device to the filter device for a predetermined length of time (liquid permeation).

  • Patent number: 8707893
    Abstract: A substrate treatment system includes a plurality of treatment apparatuses, a position adjustment apparatus adjusting a center position of the substrate, a substrate transfer apparatus transferring the substrate to the treatment apparatuses and the position adjustment apparatus, and a control unit controlling operations of the apparatuses. The substrate transfer apparatus includes an arm part curved along a peripheral edge portion of the substrate with a radius of curvature larger than a radius of the substrate, and a holding part projecting inward from the arm part and holding a rear surface of the substrate. The position adjustment apparatus includes a mounting table which holds a central portion of the rear surface of the substrate and is rotatable and horizontally movable. The control unit controls the mounting table such that the center position of the substrate held on the mounting table is aligned with a center position of the arm part.

  • Patent number: 7819594
    Abstract: A device includes a rotary base; an approach stage; a substrate holding table and a nozzle head. The substrate holding table holds the work by suction, and comes into intimate contact with the approach stage and the rotary base through first and second annular seal members to form a liquid storage space, respectively. When the suction holding and the intimate contact are released, the substrate becomes rotatable together with the rotary base and the approach stage.

  • Patent number: 7714979
    Abstract: A substrate processing apparatus enables an efficient collection of a solvent vapor discharged via a nozzle onto a wafer on which a resist pattern is formed. A retaining base that retains the wafer is moved relative to the nozzle, which includes a nozzle head. A pair of leakage preventing portions are disposed opposite to each other across the nozzle head. Each of the leakage preventing portions has an opening via which the solvent vapor discharged out of the discharge opening can be sucked, or a solvent vapor blocking gas can be discharged selectively. A solvent vapor supply source and a gas supply source are switchably connected to the supply opening of the nozzle head via a first switching valve. An exhaust pump and a solvent-vapor-blocking gas supply source are switchably connected to the openings of the leakage preventing portions via a second switching valve.

  • Patent number: 7600933
    Abstract: A substrate processing apparatus includes a substrate holding stage to hold a substrate having a surface facing up, the substrate having an exposed and developed resist pattern over the surface, a rotation driving mechanism to rotate the substrate holding stage around a vertical axis, a solvent vapor discharge nozzle having a discharge hole capable of discharging solvent vapor to swell the resist pattern onto the surface of the substrate and a vacuum opening capable of absorbing the solvent vapor discharged from the discharge hole, and a moving mechanism to move the solvent vapor discharge nozzle from an edge to a center of the substrate. The substrate is rotated around the vertical axis while moving the solvent vapor discharge nozzle from the edge to the center of the substrate, discharging the solvent vapor from the discharge hole, to supply the solvent vapor over the substrate in a spiral manner.
