Abstract:
1. A thin film deposition apparatus for forming a thin film on a substrate, the apparatus comprising: a deposition source that discharges a deposition material; a deposition source nozzle unit disposed at a side of the deposition source and including a plurality of deposition source nozzles arranged in a first direction; a patterning slit sheet disposed opposite to and spaced apart from the deposition source nozzle unit and including a plurality of patterning slits arranged in a second direction perpendicular to the first direction; a position detection member that detects a relative position of the substrate to the patterning slit sheet and including a single camera utilized to measure both distance and alignment between the patterning slit sheet and the substrate; and an alignment control member that controls a relative position of the patterning slit sheet to the substrate by using the relative position of the substrate detected by the position detection member, wherein a deposition is performed and the relative position is detected while the substrate is separated from the patterning slit sheet of the thin film deposition apparatus by a set distance and the substrate or the patterning slit sheet of the thin film deposition apparatus is moved relative to the other in the first direction, and wherein the deposition material from the deposition source nozzle unit is patterned on the substrate by the patterning slit sheet.
