  • Method of sample preparation using dual ion beam trenching
    Patent number: 11476120
    Abstract: Systems and methods of sample preparation using dual ion beam trenching are described. In an example, an inside of a semiconductor package is non-destructively imaged to determine a region of interest (ROI). A mask is positioned over the semiconductor package, and a mask window is aligned with the ROI. A first ion beam and a second ion beam are swept, simultaneously or sequentially, along an edge of the mask window to trench the semiconductor package and to expose the ROI for analysis.
    Type: Grant
