Claim 0:
1. A material deposition apparatus for depositing an evaporated material onto a substrate, the material deposition apparatus comprising:
a substrate transportation device comprising a coating drum comprising a curved drum surface and configured to transport the substrate along a substrate transportation direction, the coating drum being a gas cushion coating drum configured to provide a cooling gas between the drum surface and the substrate;
an evaporation source assembly disposed along the substrate transportation direction to provide the evaporated material to the substrate, the evaporation source assembly having a deposition area and wherein the substrate transportation device is configured to transport the substrate on the curved drum surface past the evaporation source assembly; and
at least a first heating assembly disposed along the substrate transportation direction, the first heating assembly being configured to provide a first heating area for heating the substrate, the first heating area being located directly adjacent to the deposition area of the evaporation source assembly;
wherein:
the evaporation source assembly further comprises at least one temperature-controlled shield arranged at the evaporation source assembly and delimiting the deposition area of the evaporation source assembly between a starting point of the deposition area and an end point of the deposition area;
at least part of the first heating area being located such that the substrate is simultaneously cooled by the cooling gas between the drum surface and the substrate such that heat is removed from the substrate to allow for higher deposition rates without damaging the substrate, and heated by the first heating assembly when the substrate is in the first heating area; and
the substrate directly enters the deposition area at the starting point of the deposition area when exiting the first heating area.
