  • SEMICONDUCTOR PACKAGES HAVING CONDUCTIVE PILLARS WITH INCLINED SURFACES
    Publication number: 20240136316
    Abstract: A semiconductor package includes a conductive pillar and a solder. The conductive pillar has a first sidewall and a second sidewall opposite to the first sidewall, wherein a height of the first sidewall is greater than a height of the second sidewall. The solder is disposed on and in direct contact with the conductive pillar, wherein the solder is hanging over the first sidewall and the second sidewall of conductive pillar.

  • Autofocus system and method in digital holography
    Patent number: 10241471
    Abstract: At least one embodiment relates to an autofocus method for determining a focal plane for at least one object. The method includes reconstructing a holographic image of the at least one object such as to provide a reconstructed image at a plurality of different focal depths. The reconstructed image includes a real component and an imaginary component. The method also include performing a first edge detection on the real component for at least two depths of the plurality of different focal depths and a second edge detection on the imaginary component for the at least two depths. Further, the method includes obtaining a first measure of clarity for each of the at least two depths based on a first measure of statistical dispersion with respect to the first edge detection and a second measure of clarity.
