Site‐selective tin oxide deposition from aqueous solution was performed on super‐hydrophilic surfaces. The chemical reaction and nucleation accelerated on hydroxy groups to form tin oxide nanosheets. Consequently, two‐dimensional patterns of tin oxide nanosheets were fabricated on poly(ethylene terephthalate) (PET) films coated with indium tin oxide (ITO). Tin oxide sheets grew to 100–300 nm in‐plane size and 5–10 nm thickness. Hydrophobic areas of the films suppressed formation of tin oxide structures. The site‐selective chemical reaction can be applied to allow precise control of chemical reactions, surface coating, and two‐dimensional patterning of tin oxide nanostructures for future devices.
