Title: Manufacture of x-ray mask structure
Inventor: WATANABE YUTAKA
IPC: G03F1/68
Filed: 1990-08-31
Abstract: PURPOSE:To improve the yield and working efficiency of an X-ray absorbing body forming process by performing annealing after an organic film is formed and a substrate is back-etched, and then, forming a resist pattern. CONSTITUTION:After a supporting film 12 is formed on a substrate 11, an organic film 13 is applied to the surface of the film 12. The substrate 11 is back-etched and a resist which is different from that used for the film 13 is applied. Then a resist pattern 15 is formed by drawing the pattern with an electron beam or by irradiating the substrate with X rays or ultraviolet rays after the substrate 11 is back-etched. After the pattern of an X-ray absorbing body is formed to a desired shape, the organic film is removed. Because of the organic film, the process resisting property of the inorganic film 12 used as a supporting film having an extremely thin thickness and X-ray transmissive property is improved and, by performing annealing at 100-500 deg.C after back- etching the substrate, release of the tensile stress of the inorganic film used as a supporting film is accelerated. The positional deviation of the X-ray absorbing body having a desired shape from a desired position can be suppressed to <=1/10 of the minimum line width and the yield of the X-ray absorbing body forming process is improved.

Title: Spring clutch device
Inventor: YAMAMOTO YASUYOSHI
IPC: F16D13/08
Filed: 1982-12-27
Abstract: PURPOSE:To obtain safety structure light in weight through which durability is improved and damage on the other driving system are not generated, by a method wherein a driving and driven side clutch shell components and spring are formed of resin. CONSTITUTION:A spring clutch device is formed of a driving side clutch shell 2 made of resin, which is wound around by a sping wire rod 1 made of resin transmitting power, a driven side clutch shell 3 made of the resin and a control ring 4 controlling transmission of the power. As the spring wire rod 1 is cut off when a surplus load is applied to the driven side clutch shell 3 because of the matter that the resin, whose strength is low as compared with a metallic material, is used for the spring wire rod 1, it becomes possible to interrupt turning power. In addition to the above, as a friction factor between the resin materials is low as compared with that between metal materials, when the turning power more than necessary is apt to transmit, the titled clutch is turned into a slippery state, through which the interruption of the turning power becomes possible. The other driving system, therefore, is prevented from damaging.
