Abstract: A deposition apparatus including: a base substrate; an electrostatic chuck on the base substrate; and a plate on the electrostatic chuck. The plate has a first area in which first magnet units are arranged and a second area in which second magnet units are arranged. The first magnet units are spaced apart from each other at a first distance, and the second magnet units are spaced apart from each other at a second distance. The second distance is greater than the first distance.
