  • Visualization of three-dimensional semiconductor structures
    Patent number: 11099137
    Abstract: A semiconductor metrology tool inspects an area of a semiconductor wafer. The inspected area includes a plurality of instances of a 3D semiconductor structure arranged periodically in at least one dimension. A computer system generates a model of a respective instance of the 3D semiconductor structure based on measurements collected during the inspection. The computer system renders an augmented-reality or virtual-reality (AR/VR) image of the model that shows a 3D shape of the model and provides the AR/VR image to an AR/VR viewing device for display.
    Type: Grant
    Filed: August 28, 2020
    Date of Patent: August 24, 2021
    Assignee: KLA Corporation
    Inventors: Aaron J. Rosenberg, Jonathan Iloreta, Thaddeus G. Dziura, Antonio Gellineau, Yin Xu, Kaiwen Xu, John Hench, Abhi Gunde, Andrei Veldman, Liequan Lee, Houssam Chouaib
