  • Patent number: 11355376
    Abstract: Disclosed herein are systems and methods for treating the surface of a microelectronic substrate, and in particular, relate to an apparatus and method for scanning the microelectronic substrate through a cryogenic fluid mixture used to treat an exposed surface of the microelectronic substrate. The fluid mixture may be expanded through a nozzle to form an aerosol spray or gas cluster jet (GCJ) spray and may impinge the microelectronic substrate and remove particles from the microelectronic substrate's surface. In one embodiment, a two-stage gas nozzle may be used to expand a fluid mixture with a liquid phase concentration of greater than 10% by weight.

    Abstract: Disclosed herein are systems and methods for treating the surface of a microelectronic substrate, and in particular, relate to an apparatus and method for scanning the microelectronic substrate through a cryogenic fluid mixture used to treat an exposed surface of the microelectronic substrate. The fluid mixture may be expanded through a nozzle to form an aerosol spray or gas cluster jet (GCJ) spray may impinge the microelectronic substrate and remove particles from the microelectronic substrate's surface. In one embodiment, the fluid mixture may be maintained to prevent liquid formation within the fluid mixture prior to passing the fluid mixture through the nozzle. The fluid mixture may include nitrogen, argon, helium, neon, xenon, krypton, carbon dioxide, or any combination thereof.

  • Patent number: 10020217
    Abstract: Disclosed herein are systems and methods for treating the surface of a microelectronic substrate, using a cryogenic fluid mixture used to treat an exposed surface of the microelectronic substrate. The fluid mixture may be expanded through a nozzle to form an aerosol spray or gas cluster jet (GCJ) spray may impinge the microelectronic substrate and remove particles from the microelectronic substrate's surface. The fluid mixture may include nitrogen, argon, helium, neon, xenon, krypton, carbon dioxide, or any combination thereof. The incoming fluid mixture may be maintained pressure greater than atmospheric pressure and at a temperature greater than the condensation temperature of the fluid mixture. The fluid mixture may be expanded into the treatment chamber to form an aerosol or gas cluster spray. In this embodiment, the nozzle may be positioned within 50 mm of the microelectronic substrate during the treatment, more preferably within 10 mm of the microelectronic substrate.

  • Patent number: 9059104
    Abstract: A method of selectively removing silicon nitride from a substrate comprises providing a substrate having silicon nitride on a surface thereof; and dispensing phosphoric acid and sulfuric acid onto the surface of the substrate as a mixed acid liquid stream at a temperature greater than about 150° C. In this method, water is added to a liquid solution of the mixed acid liquid stream as or after the liquid solution of the mixed acid liquid stream passes through a nozzle.

  • Patent number: 6681781
    Abstract: A method of cleaning a surface of an article using cleaning liquids in combination with acoustic energy. Preferably, an ultradilute concentration of a cleaning enhancement substance, such as ammonia gas, is dissolved in a liquid solvent, such as filtered deionized water, to form a cleaning liquid. The cleaning liquid is caused to contact the surface to be cleaned. Acoustic energy is applied to the liquid during such contact. Optionally, the surface to be cleaned can be oxidized, e.g., by ozonated water, prior to cleaning.

  • Publication number: 20030094196
    Abstract: The present invention provides immersion chemical processing systems capable of providing a desired blend of at least two chemicals to an immersion bath as well as methods of treating substrates immersively. The system is capable of producing a blend with one or more desired properties extremely accurately due at least in part to the capability of the system to monitor at least one property of the blend or at least one parameter of the immersion process and to utilize the information gathered to provide dynamic closed-loop feedback control of one or more process parameters known to relate to the same.
