  • Patent number: 11610897
    Abstract: Provided is a landing pad structure including a substrate, a plurality of landing pads, a guard ring, and an edge pattern. The substrate includes a cell region, a periphery region, and a guard ring region located between the cell region and the periphery region. The landing pads are arranged on the substrate in the cell region in a hexagonal close packing (HCP) configuration. The guard ring is disposed on the substrate in the guard ring region in a strip form. The edge pattern is disposed on the substrate in the cell region and close to the guard ring region. A method of manufacturing the landing pad structure is also provided.
    Type: Grant

  • Patent number: 10985262
    Abstract: A semiconductor structure and a manufacturing method thereof are provided. The semiconductor structure includes a substrate, a plurality of gate structures, a plurality of dielectric structures, and spacers. The plurality of gate structures is disposed on the substrate. The plurality of dielectric structures is respectively disposed between the gate structures and the substrate, wherein a top width of the dielectric structure is less than the bottom width of the dielectric structure. The spacers are disposed on the sidewalls of the gate structures and cover the sidewalls of the dielectric structures.
