  • Patent number: 8956897
    Abstract: In a method for producing an optoelectronic component, a growth substrate having a first coefficient of thermal expansion is provided. A multilayered buffer layer sequence is applied thereto. A layer sequence having a second coefficient of thermal expansion—different than the first coefficient of thermal expansion—is subsequently deposited epitaxially. It furthermore comprises an active layer for emitting electromagnetic radiation. A carrier substrate is subsequently applied on the epitaxially deposited layer sequence. The growth substrate is removed and the multilayered buffer layer sequence is structured in order to increase a coupling-out of electromagnetic radiation. Finally, contact is made with the epitaxially deposited layer sequence.
