  • Patent number: 9581526
    Abstract: An improved method and apparatus for S/TEM sample preparation and analysis. Preferred embodiments of the present invention provide improved methods for TEM sample creation, especially for small geometry (<100 nm thick) TEM lamellae. Preferred embodiments of the present invention also provide an in-line process for S/TEM based metrology on objects such as integrated circuits or other structures fabricated on semiconductor wafer by providing methods to partially or fully automate TEM sample creation, to make the process of creating and analyzing TEM samples less labor intensive, and to increase throughput and reproducibility of TEM analysis.
    Type: Grant
    Filed: February 18, 2016
    Date of Patent: February 28, 2017
    Assignee: FEI COMPANY
    Inventors: Jason Arjavac, Pei Zou, David James Tasker, Maximus Theodorus Otten, Gerhard Daniel
