Abstract:
A method of forming a thin film by having a thin film forming substance emitted from a thin film forming substance supply source arrive at and deposit on an object, comprising the steps of:providing an intercepting device placed between the supply source and the object, the intercepting device selecting between interception and allowance of arrival of the thin film forming substance at the object from the supply source; and forming the thin film having a predetermined thickness on the object, wherein the step of forming the thin film includes the steps of: having the thin film forming substance, to form the thin film having the predetermined thickness, arrive at the object from the supply source a plurality of times in an intermittent manner by shifting the intercepting device during formation of the thin film while the supply source and the object are fixed, wherein the intercepting device comprises an interceptor for intercepting arrival of the thin film forming substance from the supply source and an opening having a shape of a slit whose width is smaller than the length of the object along the direction of the width of the opening, the opening being shifted with the intercepting device and allowing deposition of the thin film forming substance on the object from the supply source; and controlling the thickness of the thin film by controlling the number of times of having the substance arrive at the object in the step of having the thin film substance arrive at the object as a result of the shifting of the opening and the intercepting device.
