A method for forming a semi-conductive or conductive oxide film is provided. The oxide film is doped with a bismuth and made of an indium oxide, an aluminum oxide, a gallium oxide, an oxide including the gallium oxide, or an oxide of a combination thereof. The method includes supplying a mist of a solution to a surface of the substrate while heating the substrate. An oxide film material and a bismuth compound being dissolved in the solution. The bismuth compound is selected from the group consisting of bismuth ethoxide, bismuth acetate oxide, bismuth acetate, bismuth nitrate pentahydrate, bismuth nitrate, bismuth oxynitrate, bismuth 2-ethylhexanoate, bismuth octanoate, bismuth naphthenate, bismuth subgallate, bismuth subsalicylate, bismuth chloride, bismuth oxychloride, bismuth citrate, bismuth oxyacetate, bismuth oxide perchlorate, bismuth oxysalicylate, bismuth bromide, bismuth iodide, bismuth hydroxide, bismuth oxycarbonate, bismuth sulfide, bismuth sulfate, bismuth carbonate, and bismuth oxide.
