  • Electronic die positioning device and method
    Patent number: 7066788
    Abstract: An autocollimator is relied upon to orient an electronic die such that its frontside is parallel to a polishing surface. The polishing device is configured such that a beam of light that is projected by the autocollimator is able to reflect off of the backside surface of the die. Measurement off of the backside surface allows the die's parallelism relative to the polishing surface to be established without removing the die from the polishing surface and allows the die's orientation to be monitored and adjusted while the frontside is being deprocessed.
    Type: Grant
    Filed: November 10, 2004
    Date of Patent: June 27, 2006
    Assignee: Ultra Tec Manufacturing, Inc.
