  • Patent number: 11387084
    Abstract: The present invention relates to a dual-station vacuum processor that pumps uniformly, comprising two vacuum processing chambers that may act as a process processing chamber, and an offset-pumping port and a vacuum pump which are common to and communicate with the two vacuum processing chambers, wherein a damper having a set thickness in a vertical direction is provided in a region proximal to the offset-pumping port in each vacuum processing chamber, so as to lower a pumping rate of gas at the pumping port proximal end and balance the pumping rate with the pumping rate of the gas at the pumping port distal end, thereby ameliorating the impact of chamber offset on the uniformity process processing. The present invention may further provide, in a rib as the damper, a channel in communication with the atmospheric environment outside of the chamber, so as to facilitate connection between a cable pipeline in the chamber and the outside.
