Claim:
1. A method for producing a semiconductor component, the method comprising: providing a semiconductor layer sequence comprising a III-V compound semiconductor material and having an active region that is provided for generating radiation, the semiconductor layer sequence also having an indicator layer; removing material of the semiconductor layer sequence that is arranged on a side of the indicator layer that is remote from the active region in regions, the material being removed using a dry-chemical removal of the semiconductor layer sequence; and monitoring a property of a process gas during the removal, and determining that the indicator layer has been reached based on a change in the property of the process gas, wherein the property of the process gas is a spectral composition of radiation emitted by the process gas, wherein the process gas comprises oxygen at least at times, and wherein the indicator layer has a higher aluminum content than a material disposed directly upstream of the indicator layer as viewed in a removal direction.
