Abstract:
1. A successive vapor deposition system, for forming an organic electroluminescence device having layers of organic materials between the anode and the cathode, in which at least some of the organic materials are heated, vaporized in a vacuum, and sequentially vapor-deposited onto a vapor deposition area of a substrate to form said layers thereon, said successive vapor deposition system comprising: a conveyor which conveys said substrate in a conveying direction parallel to a horizontal plane on which said substrate lies, wherein said vapor deposition area faces downward and is exposed through the underside of said conveyor; a plurality of vapor deposition chambers aligned in said conveying direction, wherein each of said vapor deposition chambers comprises a space through which said substrate is conveyed in said conveying direction; a plurality of containers positioned in said plurality of vapor deposition chambers, below said horizontal plane on which said substrate lies, wherein each of said containers contains one of said organic materials and has a plurality of partitions positioned therein, each of said partitions extending parallel to each other in a direction that is not perpendicular to the conveying direction and extending more than halfway up to an edge of an opening of said container, and wherein a width of each of said containers covers said vapor deposition area in a direction perpendicular to said conveying direction; and a heating medium provided for each of said containers for heating said organic materials; wherein at least one of said plurality of vapor deposition chambers is provided with at least two of said containers positioned therein, and wherein respective top openings of said at least two containers extend in a direction perpendicular to said conveying direction so that the organic materials in the at least two containers are co-deposited onto a common area on said vapor deposition area of said substrate.
