Patent ID: 8361230

Claim:
A mask holder for a mask for a large-surface substrate, the mask having a magnetic frame or edge, the mask holder comprising: a substrate carrier for receiving the substrate during a coating process, the substrate carrier comprising a substrate holding plate having a substrate-receiver area on one side and a rear side on another side, wherein the substrate carrier is constructed and arranged to be moved during the coating process together with the mask and the substrate, and wherein the substrate carrier further comprises a plurality of magnets which are directly arranged on the substrate carrier at the rear side of said substrate carrier opposite the substrate-receiver area, via a mask holding frame or a mask holding plate arranged detachably on the substrate holding plate such that the magnets are fixed between the rear side of the substrate holding plate of the substrate carrier and the mask holding frame or the mask holding plate, the magnets being spaced apart from each other peripherally around, or along a portion of an edge of, the substrate-receiver area of the substrate carrier in an annular or frame-like arrangement, and wherein the substrate carrier is constructed and arranged such that the frame or the edge of the mask may be held by the magnets of the substrate carrier, and wherein the substrate carrier with the substrate and the mask is in motion during deposition within a coating chamber, wherein the substrate carrier is constructed and arranged to position the substrate between the mask and the substrate carrier.
