  • Semiconductor chip pick and place process and equipment
    Patent number: 7028396
    Abstract: A process and tooling for removing a semiconductor chip (31) from a handling tape (321) without damage to either the chip or tape by one or more horizontal beam type ejector tools (333) driven by a variable speed motor (332) applying uniform pressure to the tape and chip backside. Each tool (333) emerges from a rigid support surface through an aperture which also serves to supply vacuum to hold the chip in alignment prior to ejection, and in turn allows planar removal of the chip by a pick-up arm (351).
    Type: Grant
    Filed: April 14, 2003
    Date of Patent: April 18, 2006
