  • Publication number: 20010037764
    Abstract: Liquid treatment units are disposed in multi-tiers surrounding a main-arm 35. Among liquid treatment units, plating units M1 through M4 are disposed on a lower tier side, and a unit for post-treatment process such as a cleaning unit 70 where a cleaner atmosphere is necessary is disposed on an upper tier side. Thereby, an improvement in an area efficiency and the formation and maintenance of a clean atmosphere can be simultaneously obtained.

  • Patent number: 5421905
    Abstract: A method for washing a group of semiconductor wafers in which a first support arrangement is provided for supporting the wafer group to be immersed in a solution, with a second support carrying the wafer group to the treatment vessel. The second support can be provided, for example, in the form of a fork arrangement, and the wafer group is transferred from the second support to the first support for treatment or washing in the treatment vessel. After the wafer group is pulled from the treatment solution, the wafer group is transferred from the first support to the second support and carried outside of the treatment vessel and transferred from the second support. Water is then sprayed onto the second support by moving a water washing nozzle along support rod(s) of the second support, and by blowing a drying gas along the second support while the second support is not carrying wafers thereon, and the next wafer group can then be supported by the clean second support.
