Title: Method for mirror polishing silicon wafer for semiconductor in specular surface
Inventor: MATSUO HIROSHI
IPC: H01L21/304
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To easily and stably obtain a wafer having one high-accuracy mirror-like surface by polishing both surfaces of a wafer after an oxide or nitride film is formed on one surface not to be polished of the wafer and removing the oxide or nitride film from the surface not to be polished after the other surface of the wafer is mirror polished. SOLUTION: An oxide or nitride film is formed on one surface not to be polished of a wafer by the CVD method or by performing heat treatment or high-temperature treatment by using a treating agent. The CVD oxide film or thermally oxidized film is hard to be polished and the thickness of the film is appropriately selected in accordance with the polishing rate of the oxide film by taking the polishing amount of the other surface to be polished of the wafer. Then the surface to be polished is mirror polished by using a double-sided polishing device which performs mechano-chemical polishing along a complicated locus and, after both surfaces of the wafer are polished by prescribed amounts, the oxide or nitride film left on the surface not to be polished is removed by dipping the wafer in an HF solution, etc.  Therefore, a wafer with one mirror-like surface having high-accuracy flatness can be obtained easily without mirror polishing the surface.

Abstract: PURPOSE:To prevent the life deterioration of a flexible tube caused by the excessive deformation rate by fitting rings to peripheral grooves on an outer periphery of the flexible tube. CONSTITUTION:Circular metal rings 9 are fitted into respective peripheral grooves 8 on an outer periphery of a flexible tube 7. The ring 9 has a circular section, and the radius thereof is substantially the same as a radius of curvature at e bottom face of the peripheral groove 8, or slightly smaller than it. When the flexible tube 7 is compressed and deformed by reception of load in the direction of the arrow A, both side walls 11 and 11 opposing to each other in the respective peripheral grooves 8 are prevented from approaching each other by means of the ring 9, so that the flexible tube 7 is prevented from being excessively compressed and deformed. The excessive expansion deformation of the flexible tube 7 caused by the compression deformation energy is also prevented. The life deterioration of the flexible tube 7 is thus suppressed.

IPC: G01N21/31
Filed: 1985-06-06
Abstract: PURPOSE:To prevent the error by the influence of the fluctuation in the light intensity of a light source by supplying intermittently a sample, storing the measuring value in the period when the sample is not supplied and subtracting the same from the measured value within the sample supply period. CONSTITUTION:An absorbancy curve having a peak in the period when the sample is supplied is obtd. when the absorbancy is measured in an absorbancy measuring instrument 25 after the light from the light source 1 is passed through a burner 20. On the other hand, the output from the instrument 25 is applied to a subtracter 27 and a memory 26. The memory 26 stores the measured ab sorbancy value in the period when the sample is not supplied. The measured value is outputted even within the sample supply period. The effect of the light intensity change in the light source 1 is therefore canceled if the output from the memory 26 is applied to the subtracter 27 and is substracted from the output measured in read time from the instrument 25 in the subtracter 27. More specifically, the measured value in the period when the sample is not supplied is subtracted from the measured absorbancy in the period when the sample is supplied within said period and the peak value of the absorbancy curve is exactly detected.
