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.
