  • Patent number: 12261082
    Abstract: The present disclosure describes a semiconductor device with a nitrided capping layer and methods for forming the same. One method includes forming a first conductive structure in a first dielectric layer on a substrate, depositing a second dielectric layer on the first conductive structure and the first dielectric layer, and forming an opening in the second dielectric layer to expose the first conductive structure and a portion of the first dielectric layer. The method further includes forming a nitrided layer on a top portion of the first conductive structure, a top portion of the portion of the first dielectric layer, sidewalls of the opening, and a top portion of the second dielectric layer, and forming a second conductive structure in the opening, where the second conductive structure is in contact with the nitrided layer.

  • Publication number: 20250081354
    Abstract: A method of manufacturing an electronic device includes providing a substrate with a predetermined first-hole region, a first surface, and a second surface. The second surface is opposite the first surface. The method includes laser processing the predetermined first-hole region from the first surface to form a first laser track and laser processing the predetermined first-hole region from the first surface to form a second laser track. The first laser track does not overlap the second laser track. The method further includes etching the predetermined first-hole region to form a first-hole.

  • Publication number: 20220349251
    Abstract: A vertical blind has a headrail, a transmission shaft, a plurality of slats located below the headrail with a gap, a driving assembly, a first clutch, a first pushing component, and a light-blocking member configured to be driven by the first pushing component to move from a blocking position coving the gap to a non-blocking position revealing at least a part of the gap. When the transmission shaft is driven to rotate in a first direction, the first pushing component is moved toward the first end of a movable region. When the first pushing component has been moved to the first end of the movable region and the transmission shaft keeps being driven to rotate in the first direction, the first clutch prevents the transmission shaft from further driving the first pushing component, whereby the first pushing component stays at substantially the first end of the movable region.
