  • EPITAXIAL FEATURES IN SEMICONDUCTOR DEVICES AND METHOD OF MANUFACTURING
    Publication number: 20240153824
    Abstract: A method includes forming a stack of channel layers and sacrificial layers over a substrate, patterning the stack to form a fin-shape structure, and recessing a portion of the fin-shape structure to form a recess. A top surface of the substrate under the recess is covered at least by a bottommost sacrificial layer of the stack. The method also includes forming inner spacers on terminal ends of the sacrificial layers that are above the bottommost sacrificial layer, depositing an undoped layer in the recess, and forming a doped epitaxial feature over the undoped layer. The undoped layer covers terminal ends of a bottommost channel layer of the stack. The doped epitaxial feature covers terminal ends of the channel layers that are above the bottommost channel layer.
