Title: Polishing method of substrate and substrate holder
Inventor: MARUYAMA MASAKAZU
IPC: B24B37/32
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To reduce the uneven degree of polishing surface of a substrate so as to provide a substrate of high quality with more satisfactory surface smoothness by moving the substrate and an outer frame integrally on a back pad surface in such a manner as to be slidable to polish the substrate. SOLUTION: After an upper surface plate 1 is moved down until a substrate 6 makes contact with an abrasive plate 8, the upper surface plate 1 is further pressed onto the abrasive plate 8 on a lower surface plate 9, whereby one side of the substrate 6 is polished by the rotating abrasive plate 8 having a large surface roughness. At that time, the sacking force between the substrate 6 and a back pad 2 is larger than the sucking force between the substrate 6 and the abrasive plate 8, and the substrate 6 is smoothly polished while slid on the lower surface of the back pad 2 at a rotating speed lower than that of the abrasive plate 8.  Since the substrate 6 is polished in the state regularly contact with different positions of the back pad surface, the pressure added to the polished surface of the substrate 6 is averaged even if the back pad surface is uneven, and an uniform polishing can be performed.

Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a diffusion demodulator by which an inverse spread output is obtained similarly to the case with the use of a multiplier without the need for the multiplier with a large circuit scale. SOLUTION: A complement-of-2 generator 2 generates data with an absolute value equal to each other but with a different sign with respect to a reception signal in advance to obtain a value equal to multiplication of '-1' by a multiplier. Since the reception signal itself is equal to a value multiplied with '1' but a multiplier, a selector 3 is used to select the reception signal or an output of the generator 2 depending on the value of the spread code so as to obtain an inverse spread output similarly to the case with using a multiplier even without the use of a multiplier having a large circuit scale.
