Abstract:
1. A vapor deposition process in which at least one vapor deposition material is heated, vaporized in a vacuum, and deposited onto a vapor deposition area of a substrate, said vapor deposition process comprising: conveying said substrate into an inner space of at least one vapor deposition chamber in a conveying direction parallel to a horizontal plane on which said substrate lies, wherein said vapor deposition area faces downward and is exposed via an opening in the underside of said conveyer; positioning said substrate, in said inner space of said vapor deposition chamber, above at least one container positioned in said inner space of said vapor deposition chamber, said container containing said vapor deposition material, wherein a width of said container covers said vapor deposition area in a direction perpendicular to said conveying direction; and heating said container to evaporate said vapor deposition material onto said vapor deposition area, wherein said vapor deposition material comprises a plurality of different vapor deposition materials; wherein at least two containers, which respectively contain a plurality of different vapor deposition materials, are provided in said at least one vapor deposition chamber; and wherein each of said plurality of containers is heated so that said plurality of different vapor deposition materials are vaporized to be co-deposited onto a common area on said vapor deposition area of said substrate.
