Title: X-ray reflector
Inventor: NAKAJIMA KUNIO
IPC: G21K1/06
Filed: 1988-06-07
Abstract: PURPOSE:To achieve a higher X-ray reflectance and a broader service wavelength range by arranging one layer containing SiC and the other layer composed of metal material in layer pairs formed by laminating multiple pairs of layers each having an X-ray dispersion characteristic one upon another. CONSTITUTION:An SiC layer 1d and a metal layer 1c (containing at least one or more of Ni, Cr, Co, Mo, Pd, Ag, Hf, Ta, W, Re, Ir, Pt and Au) are laminated alternately on a substrate made of glass, silicon or graphite. The manufacture thereof employs a physical vapor deposition by sputtering or chemical vapor deposition (CVD). The size of the layers is controlled by using a shutter or moving the substrate to a material source. The thickness of each layer is controlled by monitoring an X-ray reflectance of a film or a crystal resonator film thickness meter where the vapor deposition is conducted. As a result, a subject X-ray wavelength area can be made 0.1-200Angstrom  and an X-ray reflectance be made to 5-80%, thereby reducing scattering and absorption in the interface.

Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To stabilize the zero point by protecting a signal lead wire from magnetic flux differential noises. SOLUTION: Signal lead wires 10A and 10B are shielded against magnetism.

Title: Manufacture of semiconductor device
Inventor: YAMAMOTO YOSHIMICHI
IPC: H01L29/72
Filed: 1982-08-10
Abstract: PURPOSE:To improve the current capacity of a transistor by a method wherein, when the transistor is going to be formed, the cross section of the first diffusion layer to be used as the base is formed in such a manner that its cross section is changed into curved form. CONSTITUTION:A silicon nitride film 3 is removed using a photoresist 6 as a barrier, and then said photoresist is removed too. When a borron implanted layer 5 is driven while performing a thermal oxidization after the performance of the above-mentioned procedure, the depth of the borron implanted layer 5 becomes shallower than the region having no silicon nitride film 3, because the region in the vicinity of the place where silicon nitride film 3 is not oxidized, and the cross section in depth of the base diffusion layer 7a to be formed is formed in such a manner that it is making a gentle curved line on the emitter circumferential part. Then, an N type emitter diffusion layer 8 is formed on the prescribed region in the base diffusion region 7a, and a diffusion layer 8a for collector electrode is formed on the surface of a silicon substrate. Due to the form of the cross section of the base diffusion layer 7a located directly below the emitter diffusion layer 8, the effective base is widened on the emitter circumference and narrowered in the center part, thereby enabling to reduce the current amplification factor of the circumference, and the more the current concentrates, the more the current becomes harder to flow. Also, the current amplification factor of the emitter center part is increased, and this enables to flow a considerable current even when the potential difference with the base is small.
