Abstract: A thin film deposition apparatus according to an embodiment includes a chamber, a deposition source disposed in a chamber and that supplies a deposition material to the substrate, a mask assembly comprising pattern holes through which the deposition material passes, and an electrostatic chuck facing the mask assembly and that fixes the substrate. The electrostatic chuck comprises a body that supports the substrate, an insulating layer disposed on the body, a first electrode disposed in the insulating layer and spaced apart from the body by a first distance, a second electrode disposed in the insulating layer and spaced apart from the body by a second distance, and a conductive layer disposed in the insulating layer and spaced apart from the body by a third distance. The first electrode and the second electrode are supplied with different voltages, and the third distance is greater than the first distance.

Abstract: A deposition apparatus includes a mask, a mask frame, a stage disposed on a rear surface of the mask frame, and first to third external force applying parts disposed on the stage. Each of the first portion and the second portion includes a support and a driving part which moves the support. The first to third external force applying parts applies external force to the mask frame to control a shape of the mask frame.
