Abstract: A semiconductor device includes an active pattern protruding from a substrate, a gate structure crossing over the active pattern, and source/drain regions disposed on the active pattern at opposite sides of the gate structure. Each of the source/drain regions includes a first epitaxial pattern contacting the active pattern and a second epitaxial pattern on the first epitaxial pattern. The first epitaxial pattern comprises a material having a lattice constant which is the same as that of the substrate, and the second epitaxial pattern comprises a material having a lattice constant greater than that of the first epitaxial pattern.

Abstract: The present disclosure provides methods and apparatuses for performing sidelink-based vehicle to everything (V2X) communication. In some embodiments, an operation method includes receiving, by the second device from the first device during a first symbol period, a physical sidelink control channel (PSCCH) and a first physical sidelink shared channel (PSSCH), based on a first transmission configuration indication (TCI) state assigned to the PSCCH. The first symbol period includes first symbols on which the PSCCH and the first PSSCH are received. The operation method further includes receiving, by the second device from the first device during a second symbol period that follows the first symbol period, a second PSSCH, based on a second TCI state. The second symbol period includes second symbols on which the second PSSCH is received.
