  • SEMICONDUCTOR STRUCTURE AND FABRICATION METHOD THEREOF
    Publication number: 20240021728
    Abstract: A semiconductor structure and a method for forming semiconductor structure are provided. The semiconductor structure includes a substrate and a dielectric layer on the substrate, the dielectric layer containing gate openings. Each gate opening includes a first region and a second region on the first region. The first region has a first projection on the substrate, the second region has a second projection on the substrate. An area of the second projection is larger than an area of the first projection, and the first projection is located within the second projection. A gate layer is located in each first region and one corresponding second region.
