  • Patent number: 11695044
    Abstract: A semiconductor device is provided and includes a substrate and a stack on the substrate. The stack includes plural active layers that are vertically stacked and spaced apart from each other, and plural gate electrodes that are on the active layers, respectively, and vertically stacked. Each active layer includes a channel layer under a corresponding one of the gate electrodes, and a source/drain layer disposed at a side of the channel layer and electrically connected to the channel layer. The channel layer is made of a two-dimensional atomic layer of a first material.
    Type: Grant
    Filed: June 21, 2021
    Date of Patent: July 4, 2023

  • Patent number: 11322592
    Abstract: A semiconductor device, a field effect transistor, and a fin field effect transistor are provided. The semiconductor device may include a channel layer, a source/drain layer, and a gate electrode. The channel layer is provided on a substrate and extends in a direction perpendicular to a top surface of the substrate. The source/drain layer is disposed at a side of the channel layer and is electrically connected to the channel layer. The gate electrode is provided adjacent to at least one of surfaces of the channel layer. The channel layer includes a two-dimensional atomic layer made of a first material.
