A method of forming a vertical transistor comprising a top source/drain region, a bottom source/drain region, a channel region vertically between the top and bottom source/drain regions, and a gate operatively laterally-adjacent the channel region comprises, in multiple time-spaced microwave annealing steps, microwave annealing at least the channel region. The multiple time-spaced microwave annealing steps reduce average concentration of elemental-form H in the channel region from what it was before start of the multiple time-spaced microwave annealing steps. The reduced average concentration of elemental-form H is 0.005 to less than 1 atomic percent. Structure embodiments are disclosed.

Vertical transistor, integrated circuitry, method of forming a vertical transistor, and method of forming integrated circuitry

Methods, systems, and devices for on-die formation of single-crystal semiconductor structures are described. In some examples, a layer of semiconductor material may be deposited above one or more decks of memory cells and divided into a set of patches. A respective crystalline arrangement of each patch may be formed based on nearly or partially melting the semiconductor material, such that nucleation sites remain in the semiconductor material, from which respective crystalline arrangements may grow. Channel portions of transistors may be formed at least in part by doping regions of the crystalline arrangements of the semiconductor material. Accordingly, operation of the memory cells may be supported by lower circuitry (e.g., formed at least in part by doped portions of a crystalline semiconductor substrate), and upper circuitry (e.g., formed at least in part by doped portions of a semiconductor deposited over the memory cells and formed with a crystalline arrangement in-situ).
