Abstract: Semiconductor structures are provided. The semiconductor structure includes a substrate and nanostructures formed over the substrate. The semiconductor structure further includes a gate structure surrounding the nanostructures and a source/drain structure attached to the nanostructures. The semiconductor structure further includes a contact formed over the source/drain structure and extending into the source/drain structure.

Abstract: A light-emitting device with multi-color temperature and multi-loop configuration is provided. The light-emitting device may include a substrate, multiple light sources disposed on the substrate, a light-emitting unit covering the light sources, a first circuit and a second circuit. Each light source may be configured to emit a respective primary radiation. The light-emitting unit may include multiple loops, each of which covering at least one of the light sources. Each loop may be adjacent to and in contact with at least another loop. A first number of the light sources covered by one or more odd-numbered loops of the loops may be electrically connected to the first circuit. A second number of the light sources covered by one or more even-numbered loops of the loops may be electrically connected to the second circuit.

Abstract: A light-emitting device with multi-color temperature and multi-loop configuration is provided. The light-emitting device comprises a substrate, multiple light sources disposed on the substrate, and a light-emitting unit covering the light sources and at least a portion of the substrate. Each of the light sources is configured to emit a respective primary radiation. The light-emitting unit comprises multiple wavelength conversion components, each of which may include a respective fluorescent material. Each wavelength conversion component emits a respective converted radiation, upon absorbing a portion of the primary radiation from one or more of the light sources, and mixes the respective converted radiation with a portion of the primary radiation from the one or more of the light sources that is not absorbed to form a respective mixed radiation. Each wavelength conversion component is adjacent to, and at least partially contacts, at least another one of the wavelength conversion components.
