Abstract
A first raw material solution containing at least aluminum is atomized to generate first atomized droplets and a second raw material solution containing at least gallium and a dopant is atomized to generate second atomized droplets, and subsequently, the first atomized droplets are carried into a film forming chamber using a first carrier gas and the second atomized droplets are carried into the film forming chamber using a second carrier gas, and then the first atomized droplets and the second atomized droplets are mixed in the film forming chamber, and the mixed atomized droplets are thermally reacted in the vicinity of a surface of the base to form an oxide semiconductor film on the base, the oxide semiconductor film including, as a major component, a metal oxide containing at least aluminum and gallium, wherein the oxide semiconductor film has a mobility of no less than 5 cm/Vs.
