  • Ablation for feature recovery
    Patent number: 9842740
    Abstract: When opaque films are deposited on semi-conductor wafers, underlying features may be concealed. In accordance with one implementation, such concealed features may be re-exposed via an ablation recovery process. One ablation recovery process entails aligning an energy source with a target position on a first surface of a semiconductor wafer based on position information retrieved from a second opposite surface of the semiconductor wafer, and firing a beam of the energy source to ablate opaque material at the target position and to expose a recovery feature underlying the opaque material.
    Type: Grant
    Filed: August 25, 2015
    Date of Patent: December 12, 2017
    Assignee: SEAGATE TECHNOLOGY LLC
