Patent ID: 8137466

Claim:
A thin film deposition apparatus comprising: an electrostatic chuck comprising: a body having a supporting surface that contacts a substrate to affix the substrate by an electrostatic force, wherein the substrate is a deposition target; an electrode embedded into the body and applying the electrostatic force to the supporting surface; and a plurality of power source holes formed to expose the electrode and formed at different locations on the body; a plurality of chambers that are maintained in a vacuum state; at least one thin film deposition assembly located in at least one of the plurality of chambers and separated from the substrate by a predetermined distance, the at least one thin film deposition assembly being positioned to form a thin film on the substrate affixed to the electrostatic chuck; a carrier that moves the electrostatic chuck to pass through the plurality of chambers; a first power source plug that is attachable to and detachable from one of the power source holes in order to supply power to the electrode, the first power source plug being installed at an upstream of a path in which the electrostatic chuck is moved by the carrier; and a second power source plug that is attachable to and detachable from another of the power source holes in order to supply power to the electrode, the second power source plug being installed in the path to be downstream to the first power source plug with respect to the path, wherein the first power source plug and the second power source plug are disposed in different chambers of the plurality of chambers.
