Claim Text:
1. A thin film deposition method, comprising: forming a thin film on a substrate by jetting a deposition substance from a deposition source; measuring a thickness of the thin film while jetting the deposition substance and comparing the thickness of the thin film with a predetermined thickness; and after the measuring the thickness of the thin film and comparing the thickness of the thin film with the predetermined thickness, when the thickness of the thin film is greater than the predetermined thickness, further comprising, shielding at least a portion of a jet region of the deposition substance facing the thin film, wherein the jet region is between the substrate and the deposition source, after the measuring the thickness of the thin film and comparing the thickness of the thin film with the predetermined thickness, further comprising opening at least a portion of the jet region of the deposition substance facing the thin film when the predetermined thickness is greater than the thickness of the thin film, wherein the deposition source includes a plurality of jet nozzles that jet the deposition substance and are arranged in a first direction, and wherein the shielding or the opening at least a portion of the jet region is controlled by shielding or opening at least a portion of a jetting passageway of the deposition substance, and wherein each jet nozzle has a shutter including multiple shutter blades operating to symmetrically and axially lessen or widen an opening for the deposition substance to pass through.
