  • Publication number: 20180330991
    Abstract: An embodiment method includes providing a wafer including a first integrated circuit die, a second integrated circuit die, and a scribe line region between the first integrated circuit die and the second integrated circuit die. The method further includes forming a kerf in the scribe line region and after forming the kerf, using a mechanical sawing process to fully separate the first integrated circuit die from the second integrated circuit die. The kerf extends through a plurality of dielectric layers into a semiconductor substrate.

  • 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.

  • Publication number: 20180166328
    Abstract: A method for sawing a semiconductor wafer is provided. The method includes sawing a semiconductor wafer to form a first opening. In addition, the semiconductor wafer includes a dicing tape and a substrate attached to the dicing tape by a die attach film (DAF), and the first opening is formed in an upper portion of the substrate. The method further includes sawing through the substrate and the DAF of the semiconductor wafer from the first opening to form a middle opening under the first opening and a second opening under the middle opening, so that the semiconductor wafer is divided into two dies. In addition, a slope of a sidewall of the middle opening is different from slopes of sidewalls of the first opening and the second opening.

  • Patent number: 6824505
    Abstract: An exercise machine includes at least one body-building structure, and at least one damping structure serving to bring about a damping effect. The body-building structure is provided with an actuating pulley serving to actuate one or more weighted pulleys of the damping structure in conjunction with a cable. The actuating pulley adds a buffer to the damping effect, thereby preventing a sharp impact from inflicting an injury on a body part of an exerciser.
