  • Publication number: 20250343056
    Abstract: A substrate cleaning device includes a double-sided scrubber that directs a liquid to a substrate as it moves back-and-forth between a pair of rotating brushes. The device may also include a first set of nozzles and a second set of nozzles. The first set of nozzles may be configured to spray a first liquid at an interface between the substrate and rotating brushes and the second set of nozzles may be configured to spray a second liquid at the interface as the substrate moves back-and-forth between the pair of rotating brushes.

  • Publication number: 20250079213
    Abstract: A carrier configured to support multiple panels includes a housing having a pair of opposing sidewalls extending in a first direction and a plurality of trays stacked between the pair of opposing sidewalls in the first direction. A lid is slidably coupled to the pair of opposing sidewalls and configured to be slid on the housing between an open configuration and a closed configuration. The plurality of trays are supported in the housing such that, in the closed configuration of the lid, two trays of the plurality of trays are blocked from moving relative to one another in the first direction, and in the open configuration of the lid, the two trays are configured to be moved relative to one another in the first direction.

  • Publication number: 20250029846
    Abstract: An apparatus to separate a wafer from a pre-sliced boule of wafers may include a conveyor configured to move the pre-sliced boule of wafers from a first end to a second end. A lift yoke, positioned proximate the second end, may include a wafer slot configured to receive a first wafer of the pre-sliced boule therein when the pre-sliced boule is positioned at the second end. A pusher blade may be configured to raise the lift yoke along with the first wafer positioned in its wafer slot from a first position to a second position. The wafer slot may be vertically aligned with the conveyor at the first position and the wafer slot may be positioned above the conveyor in the second position.
