    Abstract: A substrate loading device includes an electrostatic chuck that chucks a substrate, a mask frame disposed under the electrostatic chuck, and including an edge having a flat top surface, and a plurality of holders disposed between the electrostatic chuck and the mask frame. Each of the plurality of holders includes a first connection part connected to a side of the electrostatic chuck, a second connection part connected to the first connection part and extending in a direction intersecting an extension direction of the first connection part, and a third connection part connected to the second connection part, extending in a direction intersecting an extension direction of the second connection part, and rotationally moving between a first position overlapping the substrate in a thickness direction of the substrate and a second position spaced apart from the substrate.

    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.
