    摘要: The atoms constituting a surface of a solid sample are identified by first forming, on the surface, island-like deposits of a substance capable of generating fluorescent X-rays upon being energized by an electron beam. The deposits are then energized with the electron beam so that fluorescent X-rays are emitted therefrom and reflected on the surface. From the critical angle for total reflection of the fluorescent X-rays reflected on that portion of the surface of the sample on which no deposits are present, the atoms constituting the surface may be determined. An apparatus for carrying out the above method is also disclosed which is a modification of the conventional RHEED/TRAXS device.

    摘要: Disclosed is an oxide thin film producing method and apparatus for producing an oxide thin film having excellent crystallinity and purity with high productivity while correctly controlling the composition of the oxide thin film. After reducing the pressure inside a vacuum chamber to 1.times.10.sup.-9 Torr or less, a metal thin film is formed by evaporating a specified metal element and depositing vapor of the metal element on a substrate in the vacuum chamber. Then a cover member is moved upward to closely abut to a cover receiving member to thereby form an airtight chamber for enclosing the substrate airtightly in the vacuum chamber. With the degree of vacuum around the airtight chamber maintained, O.sub.2 gas is directly introduced into the airtight chamber through a gas piping to oxidize the metal thin film and thereby form an oxide thin film. At the same time, the gas inside the airtight chamber is discharged directly out of the vacuum chamber through a gas piping.

    摘要: Disclosed is a method of forming a thin junction film including a first thin oxide flilm presenting a superconductivity and second thin oxide film presenting an insulator properties or possibly semiconductive properties with an improved production efficiency as well as improved film quality and characteristics. Employed are first and second targets each having substantially the same chemical composition excepting oxygen content. The first target is sputtered at a target cathode voltage of minus 100 V by the use of voltage derived from an external D.C. voltage source, thereby forming a first thin oxide film. Subsequently, the target is changed over to the second target while changing the target cathode voltage into self-bias voltage of minus 50 V without any change of the other film formation conditions. Through this change-over, the sputtering of the first target is successively followed by the sputtering of the second target without any interruption of time, to consequently form the second thin oxide film onto the first thin oxide film.
