Abstract: The present disclosure is directed to methods for the fabrication of buried layers in gate-all-around (GAA) transistor structures to suppress junction leakage. In some embodiments, the method includes forming a doped epitaxial layer on a substrate, forming a stack of alternating first and second nano-sheet layers on the epitaxial layer, and patterning the stack and the epitaxial layer to form a fin structure. The method includes forming a sacrificial gate structure on the fin structure, removing portions of the fin structure not covered by the sacrificial gate structure, and etching portions of the first nano-sheet layers. Additionally, the method includes forming spacer structures on the etched portions of the first nano-sheet layers and forming source/drain (S/D) epitaxial structures on the epitaxial layer abutting the second nano-sheet layers.

Abstract: A vehicle light includes a base having a compartment. At least one first light emitter and a plurality of second light emitters are disposed on a circuit board mounted in the compartment. A reflective seat is disposed in the compartment and is located in front of the first and second light emitters. The reflective seat includes at least one hollow portion aligned with the at least one first light emitter and at least one first reflective face substantially surrounding the at least one hollow portion. The at least one first light emitter is configured to emit light rays which are reflected forwards by the at least one first reflective face. A lens includes a light incoming face and a light outgoing face. The plurality of second light emitters is configured to emit light rays which are incident to the light incoming face and which exits via the light outgoing face.
