  • Publication number: 20220036678
    Abstract: A computer-implemented method of controlling access to a controlled area using a touchless experience includes under control of one or more configured computing devices, generating a QR code that is linked with the individual, and transmitting the QR code to an electronic device that is under the control of the individual. The method includes capturing an image of the QR code transmitted to the electronic device that is under the control of the individual and evaluating the captured QR code for determining whether the captured QR code matches the QR code transmitted to the electronic device that is under the control of the individual. The method includes obtaining a skin temperature reading for the individual, and capturing a facial image of the individual, and evaluating the captured facial image for determining whether the individual is wearing a face mask.

  • Patent number: 10971683
    Abstract: In some embodiments, an integrated circuit includes narrow, vertically-extending pillars that fill openings formed in the integrated circuit. In some embodiments, the openings can contain phase change material to form a phase change memory cell. The openings occupied by the pillars can be defined using crossing lines of sacrificial material, e.g., spacers, that are formed on different vertical levels. The lines of material can be formed by deposition processes that allow the formation of very thin lines. Exposed material at the intersection of the lines is selectively removed to form the openings, which have dimensions determined by the widths of the lines. The openings can be filled, for example, with phase change material.

    Abstract: A method is disclosed for forming a memory device having buried access lines (e.g., wordlines) and buried data/sense lines (e.g., digitlines) disposed below vertical cell contacts. The buried wordlines may be formed trenches in a substrate extending in a first direction, and the buried digitlines may be formed from trenches in a substrate extending in a second direction perpendicular to the first direction. The buried digitlines may be coupled to a silicon sidewall by a digitline contact disposed between the digitlines and the silicon substrate.

  • Publication number: 20110241205
    Abstract: Semiconductor devices are described that have a metal interconnect extending vertically through a portion of the device to the back side of a semiconductor substrate. A top region of the metal interconnect is located vertically below a horizontal plane containing a metal routing layer. Method of fabricating the semiconductor device can include etching a via into a semiconductor substrate, filling the via with a metal material, forming a metal routing layer subsequent to filling the via, and removing a portion of a bottom of the semiconductor substrate to expose a bottom region of the metal filled via.
