Abstract
A method can be used for producing an optoelectronic device. A first leadframe section with a component is provided. The component is designed to emit electromagnetic radiation on an emission side. The emission side faces away from the carrier. A second leadframe section is provided. In a first method step the component and the two leadframe sections are encapsulated with a first potting material in such a way that the component and the leadframe sections are embedded into a potting body, but wherein at least part of the emission area of the component remains free of the first potting material and a cutout is formed in the potting body at least above the emission area of the component. In a second method step a second potting material is molded into the cutout of the potting body, such that the emission side of the component is covered with the second potting material.
