Abstract
An object of the present invention is to provide a film forming method for an organic semiconductor film, with which an organic semiconductor film having good uniformity and high mobility can be manufactured with good productivity. A coating liquid is prepared by dissolving an organic semiconductor material in a solvent, the coating liquid is sprayed by a spray unit, and the coating liquid is applied onto a temperature-controlled substrate while the coating liquid during the flight which has been sprayed by the spray unit is being heated, whereby problems are solved.
