摘要： PROBLEM TO BE SOLVED: To provide an apparatus which can hold a mix ratio of a polishing mixture solution always at a predetermined value, and can perform polishing operation with a good accuracy without using non-production wafer for confirmation of a processing rate to thereby improve a rate of operation in the apparatus and improve a productivity in a polishing step. SOLUTION: A processing solution dropping part, which has a plurality drop ports arranged dense from which a plurality of sorts of processing solutions are dropped on a platen, is formed at a tip end of a processing solution supply piping, so that the plurality of sorts of processing solutions drop from the drop ports into a platen rotation direction onto an upstream vicinity of a processing point of a wafer to be polished. Thereby since the processing solutions reach the processing point with a mixture ratio of the plurality of sorts of processing solutions held at a predetermined value, accurate polishing can be realized without using a non-production wafer for confirmation of a processing rate.

摘要： PROBLEM TO BE SOLVED: To certainly detect abnormality of shortage and excess of microvibration of a converter before malfunction of a guide vane actually takes place. SOLUTION: This system is constituted by providing a temperature detector 11 to detect temperature of pressure oil and temperature influencing upon its adhesion and a temperature/microvibration signal conversion circuit 18 to output a microvibration signal (ag) corresponding to temperature (af) detected by the temperature detector 11. A converter coil 13 causes microvibration corresponding to current temperature by the microvibration signal (ag) output from the temperature/microvibration signal conversion circuit 18. Consequently, it is possible to prevent absorption of a pilot valve due to increase of the adhesion of the pressure oil at the time of low temperature and also it is possible to restrain excessive flow of the pressure oil of the pilot valve due to lowering of the adhesion of the pressure oil at the time of high temperature.

摘要： PROBLEM TO BE SOLVED: To smoothly oscillate an oscillation arm with good accuracy by providing the above mechanism with an oscillation shaft mounted with an oscillation arm, a rotational drive source disposed with an output shaft in parallel to the oscillation shaft adjacently to the oscillation shaft and a link mechanism for transmitting the rotation of the output shaft to the oscillation arm. SOLUTION: When a step motor is driven by rotating a washing member 12, a motor shaft 26 oscillates and the oscillation thereof is transmitted via the link mechanism 30 and the oscillation shaft 16 to the oscillation arm 14, causing the washing member 12 to oscillate so as cross a semiconductor substrate in an approximately diametral direction to wash the substrate. The oscillation of the motor shaft 26 is transmitted via the link mechanism 30 to the oscillation shaft 16 in the washing apparatus. These shafts 16 and 26 and the drive link member 31 and the driven link member 34 or the link members 32 and 34 and a connecting link member 36 are so constituted as not to give rise to shaking therebetween and, therefore, the washing member 12 may be smoothly oscillated along the surface of the substrate with the good accuracy.
