摘要 |
The present invention generally includes a coupling between components. When igniting a plasma remote from a processing chamber, the reactive gas ions may travel to the processing chamber through numerous components. The reactive gas ions may be quite hot and cause the various components to become very hot and thus, the seals between apparatus components may fail. Therefore, it may be beneficial to cool any metallic components through which the reactive gas ions may travel. However, at the interface between the cooled metallic component and a ceramic component, the ceramic component may experience a temperature gradient sufficient to crack the ceramic material due to the heat of the reactive gas ions and the coolness of the metallic component. Therefore, extending a flange of the metallic component into the ceramic component may lessen the temperature gradient at the interface and reduce cracking of the ceramic component. |
