    摘要: A container of a material supply apparatus is configured of a crucible and an orifice. The crucible has a cylindrical shape, a rectangular-column shape or the like, and is hollow. Heat sources such as heaters are disposed around the crucible. The orifice including an opening is provided on a side of the crucible in a material element supplying direction. The orifice includes a pipe portion that extends in the material element supplying direction. The opening is formed on a tip of the pipe portion. An opening area of the pipe portion is formed to become gradually narrower towards the material element supplying side, namely in a direction of the opening.

    摘要: Provided are an oxide thin film doped with an n-type impurity, and an oxide thin film device. In an oxide thin film (2), as shown in FIG. 1(b), doped oxide layers (2a) doped with an n-type (electron-conductivity type) impurity and undoped oxide layers (2b) not doped with an n-type impurity are laminated in an alternating and repeated manner. When an oxide layer is doped with the n-type impurity at a high concentration, roughness of a surface of the oxide layer becomes large. For this reason, the doped oxide layers (2a) are covered with the undoped oxide layers (2b) capable of ensuring surface flatness, before surface roughness attributable to the doped oxide layers (2a) becomes very large. Thus, a flat oxide thin film can be formed.
