  • Patent number: 10056275
    Abstract: Embodiments using immersion de-taping are described. A substrate having a substrate tape attached thereto is provided. The substrate includes electrically conductive connectors attached to the substrate tape. A fluid is provided between the substrate and the substrate tape. While the fluid is between the substrate and the substrate tape, the substrate tape is removed from the substrate. Another embodiment is an apparatus comprising an immersion tank, a substrate chuck, first and second fixed rollers, and a moveable roller. The substrate chuck is configured to secure a substrate and to place the substrate into the immersion tank. The first fixed roller is operable to dispense a clamp tape. The second fixed roller is operable to roll the clamp tape. The moveable roller is operable to extend into the immersion tank and to adhere the clamp tape to a substrate tape on the substrate.
