  • Patent number: 9039840
    Abstract: Strategies for tool designs and their uses wherein the tools can operate in either closed or open modes of operation. The tools easily transition between open and closed modes on demand. According to one general strategy, environmentally controlled pathway(s) couple the ambient to one or more process chambers. Air amplification capabilities upstream from the process chamber(s) allow substantial flows of air to be introduced into the process chamber(s) on demand. Alternatively, the fluid pathways are easily closed, such as by simple valve actuation, to block egress to the ambient through these pathways. Alternative flows of nonambient fluids can then be introduced into the process chamber(s) via pathways that are at least partially in common with the pathways used for ambient air introduction. In other strategies, gap(s) between moveable components are sealed at least with flowing gas curtains rather than by relying only upon direct physical contact for sealing.

  • Patent number: 8070884
    Abstract: Rinsing and drying a surface of a microelectronic device and the enhanced removal of rinse fluid from the surface of the microelectronic device while the microelectronic device is rotated is provided as part of a spray processing operation. Rinse fluid is generally directed to the surface of the microelectronic device by a dispensing device while one or more such microelectronic devices are supported on a turntable in a generally horizontal fashion. Drying gas is supplied after the rinsing step. During at least a portion of both rinsing and drying steps, a drying enhancement substance, such as IPA, is delivered to enhance the rinsing and drying. Particle counts and evaporation thicknesses are reduced by delivering a tensioactive compound like IPA, during at least portions of the rinsing and drying steps while a microelectronic device is controllably rotated.

  • Patent number: 7913706
    Abstract: Tool for treating microelectronic workpieces with one or more treatment materials, including liquids, gases, fluidized solids, dispersions, combinations of these, and the like. The invention provides an approach for rapid, efficient rinsing of wetted surface(s), and is particularly advantageous when used to rinse the lower surface of moveable barrier structures such as a barrier plate that overlies a workpiece being treated in such a manner to define a tapering flow channel over the workpiece. Rather than spray rinsing liquid onto the surface in a manner that generates undue splashing, droplet, or mist generation, the liquid is flowingly dispensed, preferably under laminar flow conditions, onto a surface that is in fluid communication with the surface to be rinsed. A smooth, uniform wetting and sheeting action results to accomplish rinsing with a significantly reduced risk of generating particle contamination.

  • Publication number: 20070246080
    Abstract: Improved methods of rinsing and drying microelectronic devices by way of an immersion processing apparatus are provided for effectively cleaning microelectronic devices. Methods and arrangements control the separation of one or more microelectronic devices from a liquid environment as part of a replacement of the liquid environment with a gas environment. Cleaning enhancement substance, such as IPA, is introduced into the gas environment according to a controlled profile while the separation step is conducted. The controlled profile being directed to the timing of introduction of cleaning enhancement substance, the concentration of cleaning enhancement substance and/or flow rates thereof into the vessel. Controlled timing of gas and cleaning enhancement substance delivery can also improve effectiveness of separation.
