摘要： A method for detecting an end point of a resist peeling process in which a resist is gasified to be peeled off by producing hydrogen radicals by catalytic cracking reaction where a hydrogen-containing gas contacts with a high-temperature catalyst, and contacting the produced hydrogen radicals with a resist on a substrate, includes monitoring one or more parameters indicating a state of the catalyst and detecting the end point of the resist peeling process based on variations of the monitored parameters. The hydrogen-containing gas may be a H2 gas. The parameters indicating the state of the catalyst may be one or more electrical parameters when a power is supplied to the catalyst. Further, the catalyst may be a filament made of a high melting point metal.

摘要： A processing method includes a gas having a Si—CH3 bond supplied into a processing chamber after a target substrate to be processed is loaded into the processing chamber; and a silylation process performed on the target substrate. The internal pressure of the chamber by the supply of the gas having the Si—CH3 bond and the gas supply time are set to be within ranges where the silylation process can be performed while the internal pressure of the chamber is decreased to reach an eligible pressure level where the wafer can be unloaded after the internal pressure of the chamber is increased up to a preset pressure by the supply of the gas.

摘要： A measuring head is provided with a retracting device for a sensing pin, comprising an electric motor-driven feed screw, a nut shifted by the feed screw and an inclined face formed on the nut; a seesaw member to which the sensing pin is fitted is swung by the linear motion of the inclined face to retract the sensing pin; not only can the retracting speed and the returning speed of the sensing pin be controlled as desired but also can the retracting action of the sensing pin be stopped on the way to make possible its fine positioning. Further, the electric motor may be provided with a manual knob, and the sensing pin would be thereby enabled to be manually retracted.
