  • Publication number: 20220068954
    Abstract: A semiconductor structure includes at least one set of vertical field effect transistors embedded within dielectric material layers overlying a substrate. Each vertical field effect transistor includes a bottom doped semiconductor electrode, a vertical transistor channel, a cylindrical gate dielectric, and a top doped semiconductor electrode. A three-dimensional NAND memory array can be provided over the first field effect transistors, and can be electrically connected to the vertical field effect transistors via metal interconnect structures. Alternatively, a three-dimensional NAND memory array can be formed on another substrate, which can be bonded to the substrate via metal-to-metal bonding. The vertical field effect transistors can be employed as switches for bit lines, word lines, or other components of the three-dimensional NAND memory array.
