Title: Film formation device
Inventor: FUJII HIROSHI
IPC: H01L21/205
Filed: 1987-12-26
Abstract: PURPOSE:To make films required for manufacturing VLSI's at low temperature, by equipping a film formation device with a light source to project an ultraviolet laser beam as well as an optical system to direct an ultraviolet laser beam toward the surface of a substrate and adjust the laser beam intensity. CONSTITUTION:A device comprises an optical system 8 to make an adjustment of the laser beam intensity on the surface of a substrate 2 and an optical system 9 to cause a laser beam 6 to scan two-dimentionally the surface of the substrate 2. Since the intensity of the laser beam 6 irradiated on the surface of the sub strate 2 where a film is formed is adjusted in advance, a uniform, flawless and stable film can be formed on the whole film formation area. With this device, since a thin film is available at low temperature, problems in high- temperature treatments, such as a wafer warp and a wiring break can be solved and impurity diffusion caused by high-temperature treatments can be avoided. Also, an aluminum alloy can be used in designing VLSI's, resulting in the in creased flexibility of designing VLSI's and therefore an easy manufacture of highly integrated semiconductor devices is available.

Title: Rodless cylinder
Inventor: NODA MITSUO
IPC: F15B15/24
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To move a mount smoothly, and concurrently lengthen the life of a piston by providing a slant guiding surface parallel with its axial line for the side walls of a cylinder barrel, and thereby guiding the mount by the use of the slant guiding surface. SOLUTION: Since the upper surfaces 25a of horizontal guiding rails 23 and 23 are formed to be parallel with the slit width direction, let load in each horizontal guiding rail 23 and 23 be caught only with reaction normal roughly to the slit width direction by way of guiding parts 42 and 42. Therefore, the load acts to both side walls of a cylinder barrel 1 roughly only as vertical compression force, almost no bending force is applied in the slit width direction, and the amount of deformation in the slit width direction at both side walls of the cylinder barrel is thereby extremely small. As a result, even if load acting on the upper surface of a mount 34 is made considerably great, slant guiding rails 26 and 26 can be prevented from being brought into contact heavily with the guiding surface 47a of a guiding body 47 with pressure, so that a mount 34 can thereby be moved smoothly.
