    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.

    摘要翻译： 本发明通常包括组件之间的联接。 当点燃离开处理室的等离子体时，反应气体离子可通过许多部件行进到处理室。 反应气体离子可能相当热，并导致各种部件变得非常热，因此，装置部件之间的密封可能失效。 因此，冷却反应气体离子可以通过其移动的任何金属组分可能是有益的。 然而，在冷却的金属组分和陶瓷组分之间的界面处，由于反应气体离子的热量和金属组分的冷却，陶瓷组分可能经历足以破坏陶瓷材料的温度梯度。 因此，将金属部件的凸缘延伸到陶瓷部件中可以减小界面处的温度梯度并减少陶瓷部件的开裂。

    摘要： Embodiments disclosed herein generally relate to an apparatus having an anodized gas distribution showerhead. In large area, parallel plate RF processing chambers, mastering the RF return path can be challenging. Arcing is a frequent problem encountered in RF processing chambers. To reduce arcing in RF processing chambers, straps may be coupled to the susceptor to shorten the RF return path, a ceramic or insulating or anodized shadow frame may be coupled to the susceptor during processing, and an anodized coating may be deposited onto the edge of the showerhead that is nearest the chamber walls. The anodized coating may reduce arcing between the showerhead and the chamber walls and therefore enhance film properties and increase deposition rate.
