  • Patent number: 7637272
    Abstract: The present invention provides an apparatus and method for cleaning substrates such as semiconductor wafers by sinking the substrates into cleaning fluids such as cleaning chemicals or rinsing liquids and then drying the substrates. The substrate clean and dry apparatus of present invention includes a process chamber comprising a cleaning chamber that carries the cleaning fluid and discharges at bottom the cleaning fluid; and a drying chamber above the cleaning chamber. The process chamber further includes a discharge device for evacuating the gas from the drying chamber, the gas supplied into the drying chamber. The discharge device is located between the cleaning chamber and the drying chamber, and evacuates the gas by force such that the gas is driven down vertically in the drying chamber.

  • Patent number: 7617833
    Abstract: A blocking plate 3 is disposed opposing a substrate W which is held by plural chuck pins 17 and a processing liquid is supplied from a processing liquid nozzle 5 to a space SP between the front surface Wf of the substrate and an opposed surface 3a of the blocking plate 3, whereby the processing liquid attains the liquid-tight state. While the liquid-tight state with the processing liquid is maintained, the substrate W and the blocking plate 3 rotate. In this condition, a liquid (pure water) to which ultrasonic vibration has propagated is injected from an ultrasonic nozzle 7 approximately perpendicular to a side wall surface 3b of the blocking plate 3. While the ultrasonic vibration spreads inside the blocking plate 3 along the horizontal direction, some vibrational waves spread uniformly and widely from the opposed surface 3a to the processing liquid attaining the liquid-tight state and vibrate the processing liquid.

  • Patent number: 7540295
    Abstract: A wash fluid containment system includes an elevated, fluid impervious surface upon which items to be washed are placed for washing. The surface is configured to cause wash fluid to flow to an edge of the surface and off of the surface to prevent buildup of wash fluid on the surface. A collecting trough is positioned in fluid flow communication with the edges of the surface to which the fluid flows to catch and collect the fluid as it flows from the surface. Used wash fluid is taken from the collecting trough for disposal or recycling and solids and debris can be easily removed from the trough.
