  • SEMICONDUCTOR STRUCTURE
    Publication number: 20240088224
    Abstract: A semiconductor structure includes a first gate structure, a second gate structure coupled to the first gate structure, a source region, a first drain region, and a second drain region. The source region is surrounded by the first gate structure and the second gate structure. The first drain region is separated from the source region by the first gate structure. The second drain region is separated from the source region by the second gat structure. A shape of the first drain region and a shape of the second drain region are different from each other from a plan view.
