Abstract

A method for producing a patterned organic film includes: forming a hydrophobic organic film on a hydrophilic and non-water-soluble first substrate using a coating method, pressing the organic film formed on the first substrate against a convex portion of a stamp having the convex portion and a concave portion, transferring the organic film to the convex portion by applying water or an aqueous solution to an interface between the first substrate and the organic film, and pressing the organic film transferred to the convex portion against a second substrate to transfer the organic film to the second substrate to obtain a patterned organic film, wherein at least one of the organic film and the second substrate is an organic semiconductor.
