供应清洁气体至工艺腔室的方法和系统
摘要：
本发明提出一种用以清洁工艺腔室的方法与设备。在一个实施例中，本发明提供一种工艺腔室，包括远程等离子源与工艺腔室，所述工艺腔室具有至少两个工艺区域。各工艺区域包括：基材支撑组件，设置在所述工艺区域中；气体散布系统，配置以提供气体到所述基材支撑组件上方的所述工艺区域内；以及气体通道，配置以提供气体到所述基材支撑组件下方的所述工艺区域内。第一气体导管是配置以将清洁试剂从所述远程等离子源经由所述气体散布组件流入各所述工艺区域，而第二气体导管是配置以将来自所述第一气体导管的所述清洁试剂的一部分转向到各所述工艺区域的所述气体通道。
摘要（英）：

A method and apparatus for cleaning a process chamber are provided. In one embodiment, a process chamber is provided that includes a remote plasma source and a process chamber having at least two processing regions. Each processing region includes a substrate support assembly disposed in the processing region, a gas distribution system configured to provide gas into the processing region above the substrate support assembly, and a gas passage configured to provide gas into the processing region below the substrate support assembly. A first gas conduit is configured to flow a cleaning agent from the remote plasma source through the gas distribution assembly in each processing region while a second gas conduit is configured to divert a portion of the cleaning agent from the first gas conduit to the gas passage of each processing region.
