Component with structured connection surface, and method for operating a component

A component comprising a main body and a contact structure, wherein

• the main body comprises an active zone which, at least in regions, is configured for generating electromagnetic radiation during operation of the component,
• the contact structure comprises a plurality of individually controllable segments,
• the component comprises a connection surface and a side surface, wherein the side surface extends transversely to the connection surface and is formed as a radiation passage surface of the component,
• the connection surface is formed in a structured manner, wherein the connection surface is defined by internal common interfaces between the main body and the contact structure, and wherein the segments each comprise a local common interface with the main body and are configured for injecting current into the main body in a pixelated manner,
• the component has a passivation structure which is configured for electrically insulating the segments from one another, the structured connection surface having surfaces of the passivation structure and surfaces of the individually controllable segments,
• the passivation structure comprises at least one sub-layer,
• the sub-layer is located between two adjacent segments of the contact structure in a vertical direction as well as in a lateral direction, and
• the contact structure has at least two adjacent L-shaped segments, the adjacent segments being arranged one above the other in regions as seen in plan view of the main body and thus having overlaps as seen in plan view.
