Claim 9:
10. A device for producing the chalcogen-containing compound semiconductor by the method according to claim 1, comprising:
the process chamber for providing the at least one substrate, wherein the at least one substrate is coated with the precursor for the chalcogen-containing compound semiconductor, wherein the precursor comprises at least one metal and at least one chalcogen,
at least one energy source for the heat treatment of the at least one coated substrate in the process chamber, wherein the energy source for the heat treatment comprises a radiant heater that emits heating radiation that heats the precursor,
at least one gas supply line for supplying a process gas containing the at least one gaseous chalcogen compound into the process chamber,
at least one gas discharge line for discharging the gas atmosphere from the process chamber as the waste gas,
at least one gas processor, wherein the waste gas is cooled, and the at least one gaseous chalcogen compound or the plurality of gaseous chalcogen compounds present in the process chamber after the heat treatment of the at least one coated substrate are separated from the waste gas by the conversion into the liquid or solid form in the at least one gas processor.
