  • Patent number: 11952653
    Abstract: The present disclosure provides a sputtering reaction chamber and a process assembly of the sputtering reaction chamber. The process assembly includes a liner, and the liner includes an integrally formed body member and a cover member. The cover member may extend from a bottom of the body member to an inner side of the body member and may be configured to press an edge of a to-be-processed workpiece when a process is performed. A cooling channel may be arranged in the cover member and the body member and may be configured to cool the cover member and the body member by transferring coolant. The process assembly of the sputtering reaction chamber and the sputtering reaction chamber provided by the present disclosure can reduce heat radiation of the process assembly to the to-be-processed workpiece and released gases and impurities to effectively reduce a whisker defect and improve a product yield.

  • Publication number: 20160148789
    Abstract: The present disclosure provides a pre-cleaning chamber. The pre-cleaning chamber includes a cavity, a top cover of the cavity, and an ion filtering unit with venting holes. The ion filtering unit is configured to divide the cavity into an upper sub-cavity and a lower sub-cavity and to filter out ions from plasma when the plasma is moving through the filtering unit from the upper sub-cavity to the lower sub-cavity. The pre-cleaning chamber further includes a carry unit located in the lower sub-cavity for supporting a wafer.
