  • Patent number: 8871552
    Abstract: Although Cl (chlorine) is no longer supplied in the course of a first process in which a detecting layer formed by a polycrystalline film or a polycrystalline lamination film by vapor deposition or sublimation is formed, an additional source (e.g., HCl of Cl-containing gas) other than a source is supplied at the start or in the course of the first process. Thus, the detecting layer as the polycrystalline film or the polycrystalline lamination film of CdTe, ZnTe, or CdZnTe can be doped with Cl uniformly in a thickness direction from the start until the end of the first process in film formation. As a result, uniform crystal particles and uniform detection characteristics can be achieved.
