Abstract
A method for forming a CdTe film of good quality by an improved close-spaced sublimation process is disclosed. This method comprises: a step of applying a paste which contains material for CdTe semiconductor on a supporting member, thereby to form a coating film which contains the material for the semiconductor on the surface of the supporting member; a step of closely arranging the supporting member and a substrate on which a CdTe film is to be formed, to make the coating film to face the surface of the substrate; and a step of forming a CdTe film on the substrate, by heating the coating film and the substrate, and causing the material for the semiconductor in the coating film to evaporate.
