  • SEMICONDUCTOR STRUCTURE AND MANUFACTURING METHOD THEREOF
    Publication number: 20260198044
    Abstract: A semiconductor structure includes a substrate, a plurality of active channels vertically stacked to each other, a first dielectric layer in the topmost active channel, and a first oxide layer in the topmost active channel and includes a first lateral oxide portion connected with the first dielectric layer. The first lateral oxide portion has a thickness greater than that of the first dielectric layer due to an ox-oxidation.
