  • Apparatuses comprising vertical transistors having gate electrodes at least partially recessed within channel regions, and related methods and systems
    Patent number: 11908932
    Abstract: An apparatus includes at least one vertical transistor having a channel region. The channel region includes an upper region having a first width and a lower region below the upper region and having a second width smaller than the first width. The upper region defines at least one overhang portion extending laterally beyond the lower region. The at least one vertical transistor further includes gate electrodes at least partially vertically beneath the at least one overhang portion of the upper region of the channel region. Additional apparatuses and related systems and methods are also disclosed.
