  • Patent number: 7713840
    Abstract: A semiconductor body selected from the group consisting of a semiconductor layer, a semiconductor layer sequence or a semiconductor layer structure. The semiconductor body is transferred from a growth substrate to a support material by: exposing an interface between the growth substrate and the semiconductor body or a region in the vicinity of said interface to electromagnetic radiation through one of the semiconductor body and the growth substrate; decomposing a material at or in proximity to said interface by absorption of the electromagnetic radiation in proximity to or at said interface so that the semiconductor body can be separated from the growth substrate; and connecting the semiconductor body to the support material.
    Type: Grant
    Filed: March 11, 2008
    Date of Patent: May 11, 2010
    Assignee: Osram GmbH
    Inventors: Michael Kelly, Oliver Ambacher, Martin Stutzmann, Martin Brandt, Roman Dimitrov, Robert Handschuh

  • Patent number: 7341925
    Abstract: A method for transferring a semiconductor body selected from the group consisting of a semiconductor layer, a semiconductor layer sequence or a semiconductor layer structure from a growth substrate to a support material. An interface between the growth substrate and the semiconductor body or a region in the vicinity of the interface is exposed to electromagnetic radiation through one of the semiconductor body and the growth substrate. A material at or in proximity to the interface is decomposed by absorption of the electromagnetic radiation in proximity to or at the interface so that the semiconductor body can be separated from the growth substrate. The semiconductor body is connected to the support material.

  • Patent number: 6974758
    Abstract: A method of separating two layers of material from one another in such a way that the two separated layers of material are essentially fully preserved. An interface between the two layers of material at which the layers of material are to be separated, or a region in the vicinity of the interface, is exposed to electromagnetic radiation through one of the two layers of material. The electromagnetic radiation is absorbed at the interface or in the region in the vicinity of the interface and the absorbed radiation energy induces a decomposition of material at the interface.
