Claim:
1. A fabrication method of a light emitting device, comprising: placing a substrate in a film-formation chamber, over a first crucible; evaporating a material from an evaporation source comprising the first crucible in the film-formation chamber, an opening of the first crucible facing the substrate; depositing a layer comprising the material over the substrate in the film-formation chamber by line-of-sight transfer from the opening of the first crucible to the substrate and through a mask interposed between the substrate and the first crucible; and cleaning the mask inside of the film-formation chamber after completion of the deposition, by using a plasma generating unit provided in the film-formation chamber, wherein during evaporation the substrate is rotated around a vertical axis while the first crucible is moved in a horizontal direction.
