Patent ID: 6884968

Claim:
A process for annealing a multilayer body which has a first layer and at least one second layer, wherein during annealing, a quantity of energy 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 at least one second layer, wherein at least one second layer has a defined absorption for a defined electromagnetic radiation, comprising the following process steps: a) providing an apparatus for annealing a multilayer body, which apparatus comprises an energy source comprising a first energy source and at least one second energy source emitting the defined electromagnetic radiation, and a transparency body that is semi-transparent and has a defined transmission and a defined absorption with respect to the defined electromagnetic radiation; b) arranging the multilayer body between the first energy source and the at least one second energy source, so that the first layer 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 and that the transparency body is positioned between the at least one second energy source and the at least one second layer; and c) annealing the multilayer body using the energy source to supply the quantity of energy to the multilayer body.
