Title: Plasma film forming method
Inventor: AOKI TAKESHI
IPC: H01L21/312
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming an insulating film which has a rigid bond and is composed of the CF film of high thermal stability, an interlayer insulating film of a semiconductor device, for example. SOLUTION: A compound gas of carbon and fluorine, C4 F8 gas, for example, hydrocarbon gas, C2 H4 gas, for example, gas containing silicon, SiH4 gas, for example, are used as film forming gases. The gases are made into plasma and a CF film is formed on a semiconductor wafer by the active species at the temperature of 400 deg.C. Since an Si-C bond and an Si-F bond, which are more rigid than the C-F bond, are generated in the CF film with the addition of SiH4 gas, the bond becomes rigid, degassing quantity at the high temperature becomes less and thermal stability improves.

Title: Servo control method
Inventor: SUETOMI TAKANORI
IPC: B23Q15/00
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To prevent projection compensation from being completed a little earlier even when this compensation is performed together with servo followup error compensating processing. SOLUTION: This method is provided with a position control loop, and a velocity control loop equipped with an integrator 12 and drives the feeding shaft of machine tool.

Title: Sheath for film unit
Inventor: OKUTSU TARO
IPC: G03B17/26
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To stably maintain flatness of a sheet film even when the film is exposed for a long time in a high-humidity environment. SOLUTION: Circular aeration holes 5 are formed in five lines and five columns like a check pattern in total 25 holes on a plate part 2a of a sheath 2. By the aeration holes 5, not only the emulsion face 3e of a sheet film 3 but the base face 3f is sufficiently exposed to air. When the film is exposed to light for a long time in a high-humidity environment, water vapor permeates not only into the emulsion face 3e but into the base face 3f. This prevents such a problem that only the emulsion face 3e is swollen with moisture to deform the sheet film 3 into a projecting state can be prevented, but the flatness of the sheet film 3 can be stably maintained. One aeration hole 5 has 6mm diameter and the sum area of the aeration holes 5 is 706.5mm<2> in 13416mm<2> area of the flat plate 2a.  This satisfies the preferable range of 20mm<2> to 2826mm<2> so that the air permeability of the whole base face 3f can be obtd. without decreasing the strength of the sheath 2.
