Abstract

A light emitter device contains a heater structure configured to emit light if a predefined current flows through the heater structure. The heater structure is arranged at a heater carrier structure. The light emitter device contains an upper portion of a cavity located vertically between the heater carrier structure and a cover structure. The light emitter device contains a lower portion of the cavity located vertically between the heater carrier structure and at least a portion of a carrier substrate. The heater carrier structure contains a plurality of holes connecting the upper portion of the cavity and the lower portion of the cavity. A pressure within the cavity is less than 100 mbar.
