Abstract:
An apparatus for annealing a multilayer body, said multilayer body having a first layer and at least one second layer, said apparatus comprising:an energy source, during annealing said energy source emitting a quantity of energy that is taken up by the multilayer body such that a first quantity of the quantity of energy is taken up by the first layer and a second quantity of the quantity of energy is taken up by the second layer, said energy source comprises a first energy source and at least one second energy source emitting a defined electromagnetic radiation with a radiation field; and a transparency body, which is semi-transparent and has a defined transmission and a defined absorption with respect to the defined electromagnetic radiation and is arranged in a radiation field between the second energy source and the at least one second layer, wherein one of said at least one second layer has a defined absorption for the defined electromagnetic radiation, and wherein during annealing the first layer of the multilayer body is arranged between the first energy source and the at least one second layer, and the at least one second layer is arranged between the second energy source and the first layer.
