Abstract

A pattern forming method, including an imprinting process is provided. The method includes preparing a substrate having an organic film; forming a surface film, containing at least one of a metal or a semiconductor, in or on the surface of the organic film. The method further includes forming an inorganic film on the surface film; applying an organic mask material onto the inorganic film, and pressing a template having a fine pattern against the organic mask material to form a mask pattern; processing the inorganic film using the mask pattern as a mask; and removing the mask pattern. The organic mask material, when pressed by the template, is cured or solidified by being exposed to an ultraviolet light source. The solidified organic mask includes an overflow portion removable by plasma asking and exposing the surface film underneath.
