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： The present invention generally comprises a method for cleaning a large area substrate processing chamber. As chamber volume increases, it has surprisingly been found that simply scaling up the cleaning conditions may not effectively clean silicon from the exposed chamber surfaces. Undesired silicon deposits on exposed chamber surfaces may lead to contamination in solar panel formation. Increasing the pressure of the chamber to about 10 Torr or greater while maintaining the chamber at a temperature between about 150 degrees Celsius and 250 degrees Celsius increases plasma cleaning effectiveness such that silicon deposits are removed from the chamber. The combination of high pressure and low temperature may reduce substrate contamination without sacrificing substrate throughput in solar panel fabrication.
摘要翻译：本发明通常包括清洗大面积基板处理室的方法。随着室体积的增加，令人惊讶地发现，简单地放大清洁条件可能不能有效地从暴露的室表面清洁硅。暴露的室表面上的不期望的硅沉积物可能导致太阳能电池板形成中的污染。将室的压力提高到约10托或更高，同时将室保持在约150摄氏度和250摄氏度之间的温度，增加等离子体清洁效果，使得硅沉积物从室中移除。高压和低温的组合可以减少基板污染，而不会牺牲太阳能电池板制造中的基板产量。

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.
摘要翻译：本文公开的实施方案通常涉及具有阳极氧化气体分配喷头的装置。在大面积的平行板RF处理室中，掌握RF返回路径可能具有挑战性。射频是RF处理室遇到的一个常见问题。为了减少RF处理室中的电弧，带可以耦合到基座以缩短RF返回路径，陶瓷或绝缘或阳极氧化的阴影框架可以在处理期间耦合到基座，并且阳极化涂层可以沉积在最靠近室壁的淋浴头。阳极化涂层可以减少喷头和室壁之间的电弧，并因此增强膜的性质并增加沉积速率。

摘要： An asymmetrically grounded susceptor used in a plasma processing chamber for chemical vapor deposition onto large rectangular panels supported on and grounded by the susceptor. A plurality of grounding straps are connected between the periphery of the susceptor to the grounded vacuum chamber to shorten the grounding paths for RF electrons. Flexible straps allow the susceptor to vertically move. The straps provide a conductance to ground which is asymmetric around the periphery. The straps may be evenly spaced but have different thicknesses or different shapes or be removed from available grounding point and hence provide different RF conductances. The asymmetry is selected to improve the deposition uniformity and other qualities of the PECVD deposited film.
