Abstract:
A field effect transistor construction comprises two source/drain regions and a channel region there-between. The channel region comprises a transition metal dichalcogenide material having a thickness of 1 monolayer to 7 monolayers and having a physical length between the source/drain regions. A mid-gate is operatively proximate a mid-portion of the channel region relative to the physical length. A pair of gates is operatively proximate different respective portions of the channel region from the portion of the channel region that the mid-gate is proximate. The pair of gates are spaced and electrically isolated from the mid-gate on opposite sides of the mid-gate. Gate dielectric is between a) the channel region, and b) the mid-gate and the pair of gates. Additional embodiments are disclosed.

Abstract:
Trenches are formed into semiconductive material. Masking material is formed laterally over at least elevationally inner sidewall portions of the trenches. Conductivity modifying impurity is implanted through bases of the trenches into semiconductive material there-below. Such impurity is diffused into the masking material received laterally over the elevationally inner sidewall portions of the trenches and into semiconductive material received between the trenches below a mid-channel portion. An elevationally inner source/drain is formed in the semiconductive material below the mid-channel portion. The inner source/drain portion includes said semiconductive material between the trenches which has the impurity therein. A conductive line is formed laterally over and electrically coupled to at least one of opposing sides of the inner source/drain. A gate is formed elevationally outward of and spaced from the conductive line and laterally adjacent the mid-channel portion. Other embodiments are disclosed.
