摘要: A transistor includes a first gate structure, a channel layer, and source/drain contacts. The first gate structure includes metallic nanosheets. Each of the metallic nanosheets includes a top surface, a bottom surface opposite to the top surface, and sidewalls connecting the top surface and the bottom surface. The channel layer surrounds the top surfaces, the bottom surfaces, and the sidewalls of the metallic nanosheets. The source/drain contacts are electrically connected to the channel layer. A portion of the channel layer is located between the source/drain contacts and the metallic nanosheets.
