  • Epitaxial lift off systems and methods
    Patent number: 10259206
    Abstract: Epitaxial lift off systems and methods are presented. In one embodiment a tape is disposed on the opposite side of the epitaxial material than the substrate is used to hold the epitaxial material during the etching and removal steps of the ELO process. In various embodiments, the apparatus for removing the ELO film from the substrates without damaging the ELO film may include an etchant reservoir, substrate handling and tape handling mechanisms, including mechanisms to manipulate (e.g., cause tension, peel, widen the etch gap, etc.) the lift off component during the lift off process.
    Type: Grant
    Filed: March 2, 2011
    Date of Patent: April 16, 2019
    Assignee: ALTA DEVICES, INC.
    Inventors: Brian Brown, Brian Burrows, David Berkstressor, Gang He, Thomas J Gmitter
