Patent ID: 8110509

Claim:
A method of fabricating light emitting devices by using an evaporation system including a plurality of first deposition chambers for forming a film of an organic compound layer and a plurality of second deposition chambers for forming a conductive film, said method comprising the steps of: forming a first organic compound layer over a first substrate in one of the plurality of first deposition chambers; forming a second organic compound layer over a second substrate in another of the plurality of first deposition chambers; after forming the first organic compound layer, moving the first substrate from the one of the plurality of first deposition chambers to one of the plurality of second deposition chamber by using a carrying means without being exposed to an atmosphere; moving the second substrate from the another of the plurality of first deposition chambers to another of the plurality of second deposition chambers by using the carrying means without being exposed to an atmosphere after the first substrate is moved from the one of the plurality of first deposition chambers; forming a first conductive film in contact with the first organic compound layer in the one of the plurality of second deposition chambers; and forming a second conductive film in contact with the second organic compound layer in the another of the plurality of second deposition chambers, wherein the first organic compound layer and the second organic compound layer are formed approximately in parallel.
