    • An integrated wafer loader is provided for use with a vacuum process chamber. At least one semipermeable membrane provided in the separator between upper and lower chambers of a load lock permits air flow while preventing particulate matter transfer. A micro-environment container is sealed within the upper chamber and a vacuum simultaneously produced in both upper and lower chambers. A movable carrier plate opens the micro-environment container and removes a cassette of wafers from therein and into the lower chamber. The micro-environment container remains supported by the separator and forms an impermeable barrier between the chambers. Wafers are transferred from the cassette to the process environment, and returned to the cassette after processing has been completed. The carrier plate returns the cassette containing the processed wafers to the micro-environment container for removal from the load lock chamber.
    • 提供了一个与真空处理室一起使用的集成晶片装载器。 设置在负载锁的上室和下室之间的隔板中的至少一个半透膜允许空气流动同时防止颗粒物质转移。 微环境容器被密封在上部腔室内,同时在上部和下部腔室中产生真空。 可移动的承载板打开微环境容器并从其中移除一盒晶片并进入下室。 微环境容器保持由分离器支撑,并且在室之间形成不可渗透的屏障。 晶片从盒子转移到处理环境中,并且在处理完成之后返回盒子。 承载板将包含经处理的晶片的盒带返回到微环境容器以从装载锁定室移除。
