ABSTRACT:
A main object of the present invention is to provide a manufacturing method of a plurality of pattern formed bodies which makes it possible that even if the pattern formed bodies are continuously manufactured, their property varied patterns are each made into a target pattern form with high precision. To achieve the object, the invention provides a manufacturing method of a plurality of pattern formed bodies, comprising a pattern forming step and a foreign matter removing step, wherein the pattern forming step is a step of radiating vacuum-ultraviolet light through a photomask to a pattern forming substrate, varying a surface property by the vacuum-ultraviolet light, and forming a property varied pattern with the property varied on a surface of the pattern forming substrate to form a pattern formed body; the pattern forming step is repeated plural times to manufacture a plurality of the pattern formed bodies; and the foreign matter removing step is a step performed between the repeated pattern forming steps and of radiating vacuum-ultraviolet light from the same light source as used in the pattern forming step to the photomask, in a state where the photomask and the pattern forming substrate are not opposed to each other, to remove a foreign matter deposited onto the photomask.
