    摘要: A good quality passive-state film is formed on a gas-contact face of a diaphragm of a pressure detector using a sensor chip to prevent corrosion on, or water content emission from, or catalytic action at a gas-contact face, thereby improving production quality in a semiconductor manufacturing process and providing high accuracy pressure detection. The passive-state film is formed on the gas-contact face of the diaphragm when the diaphragm is mounted on a diaphragm base. The diaphragm base is then fixedly secured to a sensor base in which a sensor chip is housed and a pressure transmitting medium is sealed in a gap between the sensor base and the diaphragm base.

    摘要: A method for supplying a specified quantity Q of processing gas while dividing at a desired flow rate ratio Q1/Q2 accurately and quickly from a gas supply facility equipped with a flow controller into a chamber. When a specified quantity Q of gas is supplied while being divided at a desired flow rate ratio Q1/Q2 from a gas supply facility equipped with a flow controller into a reduced pressure chamber C through a plurality of branch supply lines and shower plates fixed to the ends thereof, pressure type division quantity controllers FV1 and FV2 are provided in the plurality of branch supply lines GL1 and GL2. Opening control of both division quantity controllers FV1 and FV2 is started by an initial flow rate set signal from a division quantity control board FRC for fully opening the control valve CV of the pressure type division quantity controller having a higher flow rate and pressures P3′ and P3″ on the downstream side of the control valve CV are regulated thus supplying a total quantity Q=Q1+Q2 of gas while dividing into the chamber C through orifice holes (3a, 4a) made in shower plates (3, 4) at desired division quantities Q1 and Q2 represented by formulas Q1=C1P3′ and Q2=C2P3″ (where, C1 and C2 are constants dependent on the cross-sectional area of the orifice hole or the gas temperature on the upstream side thereof).

    摘要: A fluid control valve, which can control a fluid having a pressure in the order of 10 kg/cm2, has a response time in the order of several milliseconds can be made small in size, and a fluid supply/exhaust system that provides less gas counter flow in the event of a plurality of valves being used. A fluid control valve of the invention controls a fluid moving in a valve body by closing and opening a portion between a valve seat and a valve holder by use of a drive unit. The drive unit has a rod-shaped shaft for application of pressure through the valve seat and the valve holder, and a member “a” fixed around the rod-shaped shaft. The member “a” is made from a magnetic material, and has a space between it and the shaft. A coil provided in parallel to the shaft, moves the shaft via the member “a” up and down by electromagnetic induction, and makes use of a spring force to close and open a portion between the valve seat and the valve holder.

The orifice upstream side pressure P1 is adjusted by opening and closing the control valve, thereby controlling the orifice downstream side flow rate.
