Abstract:
A method for manufacturing a radiation-emitting semiconductor device and radiation-emitting semiconductor device are disclosed. In an embodiment a method includes providing a radiation-emitting semiconductor chip having a first main surface including a radiation exit surface of the semiconductor chip, applying a metallic seed layer to a second main surface of the semiconductor chip opposite to the first main surface, galvanically depositing a first metallic layer on the seed layer for forming a first electrical contact point and a second electrical contact point, galvanically depositing a second metallic layer on the first metallic layer for forming the first electrical contact point and the second electrical contact point, wherein a material of the first metallic layer and a material of the second metallic layer are different, and applying a casting compound between the contact points.
