Title: Production of metallic film
Inventor: NISHIKAWA SATORU
IPC: C23C16/14
Filed: 1989-03-01
Abstract: PURPOSE:To precisely control the thickness of a thin film of a metal forming metal fluoride by controlling irradiation time of laser by using metal fluoride and Si2F6 as gaseous raw materials and irradiating the above raw materials with ArF laser. CONSTITUTION:At the time of forming a thin film of W on the surface of an Si substrate, etc., by decomposing WF6 by means of ArF laser irradiation, a gaseous mixture of WF6 and Si2F6 is used as gaseous raw material. The above WF6 and Si2F6 as gaseous raw materials and Ar gas are introduced into a reaction chamber in which the Si substrate is placed so that their pressures are regulated to 8pa, 32pa, and 260pa, respectively. Subsequently, the inside of the reaction chamber is irradiated with ArF laser, by which Si2F6 is photodecomposed to produce SiF3 gas. This SiF3 gas is allowed to react as a reducing gas for WF6 to reduce WF6, and the resulting metallic W is formed in a thin-film state on the Si substrate. Since the reaction of producing SiF3 gas from Si2F6 takes place only by ArF laser irradiation and SiF3 gas cannot be produced by the ordinary thermal CVD method, the thickness of the thin W film can be precisely controlled by controlling the quantity of ArF laser irradiation.

Abstract: PURPOSE:To satisfactorily control the supply of power to the fixing unit of a copying machine. CONSTITUTION:A commercial power source 1 supplying power to the heater 3 of the fixing unit 2 is turned on and off by a triac Q2. A trigger means 3 asynchronously turns on and off the triac Q2 around the zerocross of the commercial power source 1.

Abstract: PURPOSE:To obtain alpha-quartz whisker having high heat resistance, chemical durability, strength, etc., and high purity suitable as a material for medical instruments with high mass productivity by calcining silicon while regulating the atmosphere, calcination temp., and the cooling rate after calcination to specified conditions, respectively. CONSTITUTION:Silicon is calcined at >=1,200 deg.C in cracked gaseous ammonia or gaseous H2 having a dew point set at -10-+13 deg.C. In this case, a cooling rate of the calcined product to at lowest 1,100 deg.C is regulated to <=30 deg.C/min. Thus, alpha-quartz whisker is generated by causing a reaction expressed by the equation. Preferred Si powder to be used as a raw material is fine powdery Si having >=about 99% purity and <=about 1mum particle size. Generation of unreacted residual Si simple substance is prevented by using a slurry of the raw material Si powder and calcining the slurry after impregnating the slurry into a porous base material (e.g., porous alumina porcelain).
