A substrate processing system in which a substrate processing apparatus comprising a deposition apparatus, a first microwave plasma processing apparatus, and a second microwave plasma processing apparatus is arranged in a cluster structure, and an organic electronic device is manufactured while maintaining a space where a target object moves from an area where the target object is carried in to an area where the target object is carried out in a desired depressurized state,
- wherein the substrate processing system:
- forms an organic element within a processing chamber of the deposition apparatus;
- generates plasma by exciting a gas including a butyne gas by microwave power and forms an amorphous hydrocarbon film to be adjacent to the organic element and cover the organic element by using the plasma, within a processing chamber of the first microwave plasma processing apparatus;
- and
- generates plasma by exciting a gas including a silane gas and a nitrogen gas by microwave power and forms a first silicon nitride film on the amorphous hydrocarbon film by using the plasma, within a processing chamber of the second microwave plasma processing apparatus.
