Deposition apparatus, method of manufacturing organic light emitting display apparatus, and organic light emitting display apparatus
A deposition apparatus for depositing a deposition material on a substrate in order to improve characteristics of a deposition layer includes: a deposition source facing the substrate and ejecting the deposition material; a patterning slit sheet including patterning slits for depositing the deposition material in a desired pattern and disposed to face the substrate; a frame coupled to the patterning slit sheet; and a stage bonded to the frame to support the frame, wherein a separation area is formed between the frame and the stage.
1. A method of manufacturing an organic light emitting display apparatus by using a deposition apparatus, the method comprising:
fixing a substrate on a transfer unit in a loading unit;
conveying the transfer unit on which the substrate is fixed into a chamber via a first conveyor unit that is installed to pass through the chamber;
forming a deposition layer by depositing a deposition material ejected from a deposition assembly on the substrate while one of the substrate or the deposition assembly moves relative to the other in a state in which the deposition assembly disposed in the chamber and the substrate are separated by a gap from each other;
separating the substrate on which the deposition material is deposited from the transfer unit in an unloading unit; and
conveying the transfer unit, from which the substrate is separated, to the loading unit via a second conveyor unit that is configured to pass through the chamber,
wherein the deposition assembly comprises a deposition source, a patterning slit sheet, a frame coupled to the patterning slit sheet, and a stage bonded to the frame, and the substrate and the patterning slit sheet are aligned with each other by using the stage,
wherein a separation area is formed between the frame and the stage.
2. The method of claim 1 , wherein the deposition apparatus comprises a plurality of deposition assemblies, and the deposition is performed successively on the substrate while the substrate passes through the plurality of deposition assemblies, and each of the deposition assemblies comprises a respective one of the deposition source, the patterning slit sheet, the frame, and the stage.
3. The method of claim 2 , wherein each of the plurality of deposition assemblies ejects a deposition material separately from each other.
4. The method of claim 1 , wherein the transfer unit circulates between the first conveyor unit and the second conveyor unit.
5. The method of claim 1 , wherein the transfer unit is conveyed in the chamber in a non-contact manner with the first conveyor unit.
