Abstract
An optoelectronic semiconductor component includes a basic body, at least one semiconductor chip arranged thereon, and an encapsulation embedding the at least one semiconductor chip and composed of a radiation-transmissive material with scattering particles. A radiation-transmissive covering layer with an absorber is applied to the encapsulation.
Claims14
An optoelectronic semiconductor component comprising:
- a basic body;
- a semiconductor chip arranged over the basic body;
- an encapsulation embedding the semiconductor chip, the encapsulation comprising a radiation-transmissive material with scattering particles;
- and
- a radiation-transmissive covering layer with an absorber overlying the encapsulation;
- wherein the scattering particles and the absorber are separated so that scattering particle density has no influence on absorption effect,
- wherein the basic body has a step in an inner area, wherein a filling level of the encapsulation in a cutout of the basic body terminates with the step and wherein the filling level of the covering layer applied to the encapsulation terminates with a surface of the basic body,
- wherein a horizontal extent of the covering layer is greater than a horizontal area of the encapsulation that terminates at the step, and
- wherein the filling level of the encapsulation in the cutout of the basic body terminates with a wave in an inner area and, wherein the filling level of the covering layer applied to the encapsulation terminates with the surface of the basic body.
