  • Patent number: 6221683
    Abstract: The invention relates to a method for producing a light-emitting component. A sequence of layers including at least one active layer is formed on the front face of a basic substrate consisting of semiconductor material. Subsequently, the basic substrate is at least partially removed and the sequence of layers is connected to an external substrate. The basic substrate is removed by wet-chemical etching in an etching agent that acts selectively on the material of the basic substrate. A first metallic contact layer is then applied to an end surface of the sequence of layers, and a second metallic contact layer is applied to an end surface of the external substrate. The sequence of layers is connected to the external substrate by connecting the first metallic contact layer to the second metallic contact layer using heat, by means of eutectic bonding.
