Abstract:
A manufacturing apparatus is provided, which can improve a utilization efficiency of an evaporation material, reduce manufacturing costs of a light emitting device having an organic light emitting element, and shorten manufacturing time necessary to manufacture a light emitting device. According to the present invention, a multi-chamber manufacturing apparatus having plural film forming chambers includes a first film forming chamber for subjecting a first substrate to evaporation and a second film forming chamber for subjecting a second substrate to evaporation. In each film forming chamber, plural organic compound layers are laminated, thereby improving the throughput. Further, it is possible that the respective substrates in the plural film forming chambers are subjected to evaporation in the same manner in parallel, while another film forming chamber undergoes cleaning.
