摘要:
A method of forming an insulating film containing silicon oxy-nitride includes a loading step, temperature raising step, oxidation step, cycle purge step, and annealing step, in this order. The temperature raising step is performed while supplying nitrogen gas and oxygen gas for preventing a silicon layer surface from being nitrided, at a supply ratio 100:1 to 1000:1. The oxidation step is performed at a temperature of 700 to 950° C. while supplying a gas that contains 1 to 5 vol % of water vapor and 95 to 99 vol % of nitrogen gas, to form a silicon oxide film. The annealing step is performed at a temperature of 800 to 950° C. while supplying a gas that contains 10 to 100 vol % of nitrogen monoxide gas, to convert a portion of the silicon oxide film into silicon oxy-nitride.

A manufacturing method for semiconductor devices that can improve uniformity in the surface of a silicon nitride film or a nitride film to be formed and improve production efficiency is provided. A step of forming a first film that is a silicon oxide film or a silicon oxynitride film on a silicon substrate, a step of forming a second film that is a tetrachlorosilane monomolecular layer, and a step of forming a third film that is a silicon nitride monomolecular layer by performing a nitriding process on the second film are included. A silicon nitride film having a predetermined film thickness is formed by repeating the step of forming the second film and the step of forming the third film for a predetermined number of times. In a manufacturing apparatus, a plurality of silicon substrates are arranged on a stair-like wafer boat, and a process gas is supplied toward the upper side of a reaction tube from a process gas supply pipe.

A pump body 10 of a drainage pump 1A comprises a pump chamber 12, inlet 15, and outlet 17. A rotary vane 300 mounted in the pump body 10 is coupled to a motor mounted above the pump body 10, and comprises a shaft 310 and four large-radial blades 320. Formed below the large-radial blades 320 are small-radial blades 350 to make a liquid at the inlet rise. Lower edges of the large-radial blades 320 are connected together by a disk 350 having an opening at the center and interceptively dividing the surface of the liquid rising from the inlet. Thus the amount of the liquid in contact with the large-radial blades 320 above the disk 350 decreases, and the load to the rotary vane decreases. At the same time, bubbles, noise and vibrations caused by bubbles also decrease. By surrounding the outer circumference of the large-radial blades 320 with a ring member, return water W5 moving back from the outlet 17 when the pump stops is damped by the wall member 360 and returns smoothly to the inlet 15.

Oppositely of a temperature measuring surface of an object-to-be-measured 16, a reflecting member 28 is disposed while being spaced by a reflection gap 35 from the temperature measuring surface. The reflecting member 28 is composed of a heat ray reflecting material capable of reflecting heat ray in a specific wavelength band, in a portion including a reflection surface 35a. A heat ray extraction pathway section 30 is disposed through the reflecting member 28 so that one end thereof faces the temperature measuring surface. Heat ray extracted through the heat ray extraction pathway section from the reflection gap is detected by a temperature detection section 34. The heat ray reflecting material is configured in a form of a stack comprising a plurality of element reflecting layers composed of a material having transparent properties to the heat ray, in which every adjacent two element reflecting layers are composed of a combination of materials having refractive indices which differ from each other by 1.1 or more. This makes the measurement be hardly affected by radiation ratio of the object-to-be-measured when temperature of the object-to-be-measured is measured by a radiation thermometer, enables to measure its temperature more correctly irrespective of the surface state thereof, and can simplify configuration of a measurement system.
