  • Method for fabricating multi-layer thin film structure having a separation layer
    Patent number: 5534094
    Abstract: A method and apparatus for releasing a workpiece from a substrate including providing a substrate which is transparent to a predetermined wavelength of electromagnetic radiation; forming, on the substrate, a separation layer which degrades in response to the predetermined radiation; providing the workpiece on the separation layer; and directing the predetermined radiation at the separation layer through the transparent substrate so as to degrade the separation layer and to separate the workpiece from the substrate.
    Type: Grant
    Filed: September 29, 1994
    Date of Patent: July 9, 1996
    Assignee: IBM Corporation
