Abstract

A component includes a carrier and a semiconductor body arranged on the carrier, wherein the semiconductor body has an active layer arranged between the first and second semiconductor layers and is configured to generate, during operation of the component, an electromagnetic radiation that can be coupled out from the component through a first main surface, the first main surface of the component has an electrical contact layer configured to electrically contact a first semiconductor layer and in a plan view the carrier covers the first main surface in places, and in direct vicinity of the electrical contact layer the component includes a shielding structure configured to prevent electromagnetic radiation generated by the active layer from impinging onto the contact layer.
