摘要： The present invention provides a reliable, non-invasive, electrical test method for predicting satisfactory performance of electrostatic chucks (ESCs). In accordance with an aspect of the present invention, a parameter, e.g., impedance, of an ESC is measured over a frequency band to generate a parameter functions. This parameter function may be used to establish predetermined acceptable limits of the parameter within the frequency band.

摘要： A method for optimizing a dechuck sequence, which includes removing a substrate from a lower electrode. The method includes performing an initial analysis to determine if a first set of electrical characteristic data of a plasma formed during the dechuck sequence traverses a threshold values. If so, turning off the inert gas. The method also includes raising the lifter pins slightly from the lower electrode to move the substrate in an upward direction. The method further includes performing a mechanical and electrical analysis, which includes comparing a first set of mechanical data, which includes an amount of force exerted by the lifter pins, against a threshold value. The mechanical and electrical analysis also includes comparing a second set of electrical characteristic data against a threshold value. If both traverse the respective threshold value, removes the substrate from the lower electrode since a substrate-released event has occurred.
摘要翻译：一种用于优化解扣序列的方法，其包括从下电极去除衬底。该方法包括执行初始分析以确定在解扣序列期间形成的等离子体的第一组电特性数据是否穿过阈值。如果是这样，关闭惰性气体。该方法还包括从下电极稍微升高升降器销，以向上移动基板。该方法还包括执行机械和电气分析，其包括将包括提升器引脚施加的力的第一组机械数据与阈值进行比较。机械和电气分析还包括将第二组电特性数据与阈值进行比较。如果两者都穿过相应的阈值，则由于发生了衬底释放事件而从底部电极去除衬底。

摘要： An electrostatic chuck assembly is provided comprising a ceramic contact layer, a patterned bonding layer, an electrically conductive base plate, and a subterranean arc mitigation layer. The ceramic contact layer and the electrically conductive base plate cooperate to define a plurality of hybrid gas distribution channels formed in a subterranean portion of the electrostatic chuck assembly. Individual ones of the hybrid gas distribution channels comprise surfaces of relatively high electrical conductivity presented by the electrically conductive base plate and relatively low electrical conductivity presented by the ceramic contact layer. The subterranean arc mitigation layer comprises a layer of relatively low electrical conductivity and is formed over the relatively high conductivity surfaces of the hybrid gas distribution channels in the subterranean portion of the electrostatic chuck assembly. Semiconductor wafer processing chambers are also provided.
