Abstract: An electronic device comprising a cell region comprising stacks of alternating dielectric materials and conductive materials. A pillar region is adjacent to the cell region and comprises storage node segments adjacent to adjoining oxide materials and adjacent to a tunnel region. The storage node segments are separated by a vertical portion of the tunnel region. A high-k dielectric material is adjacent to the conductive materials of the cell region and to the adjoining oxide materials of the pillar region. Additional electronic devices are disclosed, as are methods of forming an electronic device and related systems.

Abstract: A method of forming a pattern on a substrate comprises forming spaced, upwardly-open, cylinder-like structures projecting longitudinally outward of a base. Sidewall lining is formed over inner and over outer sidewalls of the cylinder-like structures, and that forms interstitial spaces laterally outward of the cylinder-like structures. The interstitial spaces are individually surrounded by longitudinally-contacting sidewall linings that are over outer sidewalls of four of the cylinder-like structures. Other embodiments are disclosed, including structure independent of method.

Abstract: Some embodiments include a construction having conductive structures spaced from one another by intervening regions. Insulative structures are within the intervening regions. The insulative structures include dielectric spacers and air gaps between the dielectric spacers. Dielectric capping material is over the air gaps. The dielectric capping material is between the dielectric spacers and not over upper surfaces of the dielectric spacers. Some embodiments include a construction having a first conductive structure with an upper surface, and having a plurality of second conductive structures electrically coupled with the upper surface of the first conductive structure and spaced from one another by intervening regions. Air gap/spacer insulative structures are within the intervening regions. The air gap/spacer insulative structures have dielectric spacers along sidewalls of the second conductive structures and air gaps between the dielectric spacers. Dielectric capping material is over the air gaps.

Abstract: A method of forming a pattern on a substrate includes forming spaced first material-comprising pillars projecting elevationally outward of first openings formed in second material. Sidewall spacers are formed over sidewalls of the first material-comprising pillars. The sidewall spacers form interstitial spaces laterally outward of the first material-comprising pillars. The interstitial spaces are individually surrounded by longitudinally-contacting sidewall spacers that are over sidewalls of four of the first material-comprising pillars.
