  • Patent number: 11951638
    Abstract: A method for determining a standard depth value of a marker includes obtaining a maximum depth value of the marker. A reference depth value of the marker is obtained based on a depth image of the marker, and a Z-axis coordinate value of the marker is obtained based on a color image of the marker. When the reference depth value and the Z-axis coordinate value are both less than the maximum depth value, and a difference between the reference depth value and the Z-axis coordinate value is not greater than 0, the depth reference value is set as the standard depth value of the marker; and when the difference is greater than 0, the Z-axis coordinate value is set as the standard depth value of the marker.

  • Publication number: 20240084455
    Abstract: Some implementations described herein include systems and techniques for fabricating a wafer-on-wafer product using a filled lateral gap between beveled regions of wafers included in a stacked-wafer assembly and along a perimeter region of the stacked-wafer assembly. The systems and techniques include a deposition tool having an electrode with a protrusion that enhances an electromagnetic field along the perimeter region of the stacked-wafer assembly during a deposition operation performed by the deposition tool. Relative to an electromagnetic field generated by a deposition tool not including the electrode with the protrusion, the enhanced electromagnetic field improves the deposition operation so that a supporting fill material may be sufficiently deposited.
