  • Method of protecting a mounting tape during laser singulation of a wafer
    Patent number: 9449877
    Abstract: A method of singulating a semiconductor wafer with laser energy while the semiconductor wafer is supported on a mounting tape during singulation comprises the step of depositing a coating material onto a portion of the mounting tape adjacent to a perimeter of the semiconductor wafer to form a protective layer over the mounting tape. The semiconductor wafer is then cut with a laser beam such that the laser beam at least partially impinges upon the protective layer during cutting of the semiconductor wafer. After singulation of the semiconductor wafer, the protective layer is removed from the mounting tape.
    Type: Grant
