  • Patent number: 11658277
    Abstract: A method for producing an optoelectronic component and an optoelectronic component are disclosed. In an embodiment a method includes providing a semiconductor chip having an active region for radiation emission, applying a seed layer on the semiconductor chip, wherein the seed layer includes a first metal and a second metal being different from the first metal, and wherein the second metal is less noble than the first metal, applying a structured photoresist layer directly to the seed layer, applying a solder layer at least to regions of the seed layer which are not covered by the photoresist layer and wherein a proportion of the second metal in the seed layer is between 0.5 wt % and 10 wt %.
    Type: Grant

  • Patent number: 11081620
    Abstract: A method of producing a semiconductor component includes applying an auxiliary carrier at a first side of a semiconductor body, the auxiliary carrier having a first lateral coefficient of thermal expansion, and applying a connection carrier at a second side of the semiconductor body facing away from the auxiliary carrier, the connection carrier having a second lateral coefficient of thermal expansion, wherein the semiconductor body is grown on a growth substrate different from the auxiliary carrier, the first and the second lateral coefficient of thermal expansion differ by at most 50%, and the growth substrate is removed prior to application of the auxiliary carrier.

  • Publication number: 20200274031
    Abstract: A method for producing an optoelectronic component by providing a semiconductor layer sequence on a substrate where the semiconductor layer sequence is configured to emit radiation. The method may further include applying a contact layer to the semiconductor layer sequence where the contact layer has a layer thickness of at most 10 nm. The method may further include applying a reflective layer to the contact layer and applying a barrier layer directly to the reflective layer.
