  • Patent number: 11257707
    Abstract: A substrate gripping mechanism, for gripping a substrate between a fixed clamp portion to be engaged with an edge portion of a substrate and a movable clamp portion configured to reciprocate with respect to the fixed clamp portion by a reciprocating driving unit, includes an interlocking member configured to move together with the movable clamp portion, and a first sensor and a second sensor, each having a detection region and configured to detect whether or not the interlocking member exists in the detection region. The interlocking member has a first to a fourth portion connected in a reciprocating direction of the movable clamp portion. The first to the fourth portion have shapes to make detection results thereof by the first sensor and the second sensor different from each other.

  • Publication number: 20220051928
    Abstract: A transfer device for simultaneously or separately transferring a wafer and a consumable part having a circular shape is disclosed. The consumable part is disposed in a wafer processing module, and the outer diameter of the consumable part is larger than the outer diameter of the wafer. The transfer device comprises an end effector configured to place the wafer and the consumable part thereon simultaneously or separately, an arm configured to move the end effector, and a controller configured to control the arm, to place the consumable part on the end effector such that the center of gravity of the consumable part coincides with a first position when transferring the consumable part, and to place the wafer on the end effector such that the center of gravity of the wafer coincides with a second position between the first position and front ends of the end effector when transferring the wafer.

  • Publication number: 20220013339
    Abstract: There is provided a substrate support of a plasma processing apparatus. The substrate support includes a wafer placement surface and a ring placement surface on which a first ring and a second ring disposed at an outer peripheral side of the first ring without overlapping with the first ring in a vertical direction are placed, with a hole at a boundary between the first ring and the second ring. The substrate support further includes a lifter pin having a first holding portion and a second holding portion, the second holding portion being unitary with and extending axially from a base end of the first holding portion and having a protruding portion protruding from an outer circumference of the first holding portion, and a driving mechanism configured to raise and lower the lifter pin.

  • Patent number: 9805960
    Abstract: When an edge of a wafer passes above a right sensor and a left sensor disposed in a conveyance route of the wafer to a substrate processing chamber, four edge intersecting points are acquired in a first wafer coordinate system, and a reference edge intersecting point set composed of two adjacent edge intersecting points is created from the four edge intersecting points. Between the two remaining edge intersecting points which do not constitute the reference edge intersecting point set, an edge intersecting point present within an area surrounded by two circles defined based on the two edge intersecting points constituting the reference edge intersecting point set is selected as an effective edge intersecting point, and a central position of a circle passing through the reference edge intersecting points and the effective edge intersecting point is acquired as a central position of the wafer.
