  • EPITAXIAL STRUCTURES FOR SEMICONDUCTOR DEVICES AND MANUFACTURING METHODS THEREOF
    Publication number: 20250022957
    Abstract: The present disclosure provides a semiconductor device and a method of forming the same. A method according one embodiment of the present disclosure include forming a stack over a substrate, forming a fin-shape structure from patterning the stack and the substrate, recessing the fin-shape structure to form a source/drain trench, depositing a dielectric film in the source/drain trench with a top surface below a top surface of the substrate in the fin-shape structure, and forming an epitaxial feature over the dielectric film. A bottom surface of the epitaxial feature is below the top surface of the substrate in the fin-shape structure.
