Patent ID: 7651722

Claim:
A method of manufacturing an organic electroluminescence display, the method comprising the steps of: providing a substrate; forming a first electrode layer on the substrate in a predetermined pattern; aligning in a first alignment chamber a mask having openings corresponding to the predetermined pattern with the substrate on which the first electrode layer is formed; detachably attaching the mask and the substrate with a magnetic force; transferring the mask and the substrate in a magnetically attached state to a first formation unit; forming a first organic layer for a first color by sequentially forming a plurality of organic material layers in a plurality of vacuum processing chambers in the first formation unit; transferring the mask and the substrate in an attached state to a second alignment chamber connecting the first formation unit to a second formation unit, such that the first formation unit, the second alignment chamber and the second formation unit are connected in series, thereby providing for flow-through processing; realigning in the second alignment chamber the mask with the substrate; detachably reattaching the mask and the substrate with a magnetic force; transferring the mask and the substrate in a magnetically attached state to the second formation unit; forming a second organic layer for a second color by sequentially forming a plurality of organic material layers in a plurality of vacuum processing chambers in the second formation unit; the first and second organic layers being stacked on the first electrode layer formed on the substrate; and forming a second electrode layer on the first and second organic layers, wherein the steps of attaching and separating the mask and the substrate and the step of transferring the attached mask and substrate are all performed in a vacuum atmosphere, and wherein for each of the first and second organic layers, the substrate is attached to the mask with a magnetic force throughout the formation of the organic layer such that the mask and the substrate do not require realignment with each other during the formation of the plurality of organic material layers.
