Patent ID: 8193011

Claim:
A method of manufacturing an organic light-emitting device, the method comprising: affixing a substrate which is a deposition target to an electrostatic chuck, wherein the electrostatic chuck comprises a body having a supporting surface that contacts the substrate to affix the substrate by an electrostatic force, an electrode embedded into the body and applying an electrostatic force to the supporting surface, and a plurality of power source holes that are formed to expose the electrode and that are formed at different locations on the body; moving the electrostatic chuck supporting the substrate to pass through a plurality of chambers that are maintained in a vacuum state, wherein at least one of a plurality of power source plugs is engaged with a power source hole of the plurality of power source holes at all times when the substrate is supported by the electrostatic chuck and when the electrostatic chuck passes through the plurality of chambers; inserting a first power source plug of the plurality of power source plugs into a first power source hole selected from among the plurality of power source holes to supply power to the electrode, where the first power source plug is installed at an upstream of a path in which the electrostatic chuck is moved; inserting a second power source plug of the plurality of power source plugs into a second power source hole selected from among the plurality of power source holes to supply power to the electrode, where the second power source plug is installed in the path to be downstream to the first power source plug with respect to the path; separating the first power source plug from the first power source hole; and forming an organic layer on the substrate by using a thin film deposition assembly disposed in at least one of the plurality of chambers and by moving the electrostatic chuck supporting the substrate or the thin film deposition assembly relative to the other.
