Some embodiments include an integrated assembly having first conductive structures extending along a first direction. Spaced-apart upwardly-opening container-shapes are over the first conductive structures. Each of the container-shapes has a first sidewall region, a second sidewall region, and a bottom region extending from the first sidewall region to the second sidewall region. Each of the first and second sidewall regions includes a lower source/drain region, an upper source/drain region, and a channel region between the upper and lower source/drain regions. The lower source/drain regions are electrically coupled with the first conductive structures. Second conductive structures extend along a second direction which crosses the first direction. The second conductive structures have gate regions operatively adjacent the channel regions. Storage elements are electrically coupled with the upper source/drain regions. Some embodiments include methods of forming integrated assemblies.

An embodiment of the invention comprises a method of forming a transistor comprising forming a gate construction having an elevationally-outermost surface of conductive gate material that is lower than an elevationally-outer surface of semiconductor material that is aside and above both sides of the gate construction. Tops of the semiconductor material and the conductive gate material are covered with masking material, two pairs of two opposing sidewall surfaces of the semiconductor material are laterally exposed above both of the sides of the gate construction. After the covering, the semiconductor material that is above both of the sides of the gate construction is subjected to monolayer doping through each of the laterally-exposed two opposing sidewall surfaces of each of the two pairs and forming there-from doped source/drain regions above both of the sides of the gate construction.

Fin-FET (fin field-effect transistor) devices and methods of fabrication are disclosed. The fin-FET devices include dual fin structures that may form a channel region between a source region and a drain region. In some embodiments, the dual fin structures are formed by forming shallow trench isolation structures, using a pair of shallow trench isolation (STI) structures as a mask to define a recess in a portion of a substrate between the pair of STI structures, and recessing the pair of STI structures so that the resulting dual fin structures protrude from an active surface of the substrate. The dual fin structures may be used to form single-gate, double-gate, or triple-gate fin-FET devices. Electronic systems including such fin-FET devices are also disclosed.

At least some of the masking material is removed from the opening. A gate dielectric is formed radially about the pillar. Conductive gate material is formed radially about the gate dielectric. An upper portion of the pillar is formed to comprise one source/drain region of the vertical transistor. Semiconductive material of the pillar received below the upper portion is formed to comprise a channel region of the vertical transistor. Semiconductor material adjacent the opening is formed to comprise another source/drain region of the vertical transistor. Other aspects and implementations are contemplated.
