  • Patent number: 11967272
    Abstract: A sweep voltage generator and a display panel are provided. The sweep voltage generator includes an output node, a current generating block and a voltage regulating block. The output node is used to provide a sweep signal. The current generating block is coupled to the output node, includes a detection path for detecting an output load variation on the output node, and adjusts the sweep signal provided by the output node based on the output load variation. The voltage regulating block is coupled to the output node for regulating a voltage of the output node.

  • Publication number: 20240087896
    Abstract: Methods of forming line-end extensions and devices having line-end extensions are provided. In some embodiments, a method includes forming a patterned photoresist on a first region of a hard mask layer. A line-end extension region is formed in the hard mask layer. The line-end extension region extends laterally outward from an end of the first region of the hard mask layer. The line-end extension region may be formed by changing a physical property of the hard mask layer at the line-end extension region.

  • Publication number: 20240068124
    Abstract: An apparatus for producing silicon carbide crystal is provided and includes a composite structure formed by a plurality of graphite layers and silicon carbide seed crystals, wherein a density or thickness of each layer of graphite is gradually adjusted to reduce a difference of a thermal expansion coefficient and Young's modulus between the graphite layers and silicon carbide. The composite structure can be stabilized on a top portion or an upper cover of a crucible made of graphite, thereby preventing the silicon carbide crystal from falling off.
