    Abstract: A glass workpiece processed in a vacuum plasma processing chamber is dechucked from a monopolar electrostatic chuck by gradually reducing the chucking voltage during processing while maintaining the voltage high enough to clamp the workpiece. The chucking voltage during processing is controlled in response to flow rate of a heat transfer fluid flowing to the chuck to maintain the chucking force and the flow rate approximately constant. A reverse polarity voltage applied to the chuck at the end of processing assists in dechucking. The workpiece temperature is maintained at a high value at the end of processing to assisting in dechucking. Peak current flowing through the chuck during workpiece lifting from the chuck controls the amplitude and/or duration of the reverse polarity voltage during the next dechucking operation. An inert plasma in the chamber removes residual charge from the workpiece after workpiece lifting from the chuck.

    Abstract translation: 在真空等离子体处理室中处理的玻璃工件通过在处理过程中逐渐减小夹紧电压而从单极静电夹盘脱开,同时保持足够高的电压以夹紧工件。 加工过程中的夹紧电压响应于流向卡盘的传热流体的流量而被控制,以保持夹紧力和流量大致恒定。 在加工结束时施加在卡盘上的反向极性电压有助于去夹紧。 在加工结束时,工件温度保持在较高值,以帮助脱开夹紧。 在工件从卡盘上提升期间流过卡盘的峰值电流在下一次脱开操作期间控制反极性电压的幅度和/或持续时间。 工件从卡盘上提升后,腔室内的惰性等离子体会去除工件上的残余电荷。

    Abstract: PROBLEM TO BE SOLVED: To provide a new improved method and a new improved apparatus for chucking and dechucking a workpiece electrostatically in a vacuum plasma processor. SOLUTION: A glass workpiece 32 processed in a vacuum plasma processing chamber 10 is dechucked by gradually reducing the chucking voltage during processing while maintaining the voltage high enough to clamp the workpiece. The chucking voltage during processing is controlled in response to chucking force and flow rate of a heat transfer fluid flowing to the chuck. A reverse polarity voltage applied to the chuck at the end of processing assists in dechucking. The workpiece temperature is maintained at a high value at the end of processing. A peak current flowing through the chuck during workpiece lifting from the chuck controls the amplitude and/or duration of the reverse polarity voltage during the next dechucking operation. An inert plasma in the chamber 10 removes a residual charge from the workpiece 32 after workpiece lifting from the chuck 30. COPYRIGHT: (C)2010,JPO&INPIT

SOLUTION: A glass workpiece 32 being processed in a vacuum plasma processing chamber is dechucked from a monopolar electrostatic chuck by gradually reducing chucking voltage during the processing while voltage is maintained high enough to clamp the workpiece. A reverse polarity voltage, which is applied to the chuck at a final step of the processing, assists the dechucking. The workpiece temperature is maintained at a high value at the final step of the processing in order to assist the dechucking.
