Title: Method of polishing substrate
Inventor: KURATA YASUSHI
IPC: H01L21/304
Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To enable a silicon oxide film and a metal buried film to be effectively flattened at a high level, excessive film layers to be effectively removed from the films, and the surfaces of the films to be almost kept free from polishing marks through a recess CMP(chemical mechanical polishing) technique where a shallow trench isolation is made, and a metal buried wiring is formed. SOLUTION: This method is used for polishing a substrate of certain structure where a silicon nitride film is formed as a stopper by the use of abrasive material which contains abrasive grains and additives. The method comprises a first process where the protrudent part of a pattern on the substrate is selectively polished discriminating it from the recess with abrasive material prescribed in additive concentration and a second process where the surface of the substrate is polished with abrasive material whose additive weight concentration is 0 to 0.8 with regard to 1 of the abrasive material concentration used in the first process.

Title: Shaft fixing device and input/output device using it
Inventor: AKAHA HISAYUKI
IPC: F16C13/02
Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To facilitate fixing and hardly cause looseness by providing a small-diameter part having a D-shaped section, which is vertical in the axial direction on at least one end part of a fixed shaft and a hole part having a sectional form in which the small-diameter part can be inserted on at least one side of a bearing part. SOLUTION: A small-diameter part 412 of a driving shaft 41 has a D-shaped sectional form vertical to the axial direction, and with the end part 413 movably supported by a second bearing 43, the small-diameter part 412 is inserted in a hole 421 of a first bearing 42. The sectional form of the small-diameter part 412 corresponds to the shape of the hole 421, and the terminal part of the small-diameter part 412 is a tapered surface to be easily inserted. Subsequently, an E-ring 44 is mounted in a groove part 415 of the small-diameter part 412. Since the inside diameter of the ring 44 is smaller than the outside diameter of the groove part 415, falling-off can be prevented, and since the outside diameter of the ring 44 is larger than the inside diameter of the hole 421, the small-diameter part 412 is kept from being slipped off the bearing 42 after the ring 44 is mounted.  Accordingly, the driving shaft can be fixed to the bearing only by fixing the side end part of the small-diameter part with the E-ring, and the driving shaft can be also kept from being rotated. Furthermore, the occurrence of looseness can be reduced over a long period of time as compared with nut fixing.

Title: Defect inspection method and device
Inventor: YOKOYAMA KOICHI
IPC: G01N21/892
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To improve inspection accuracy by performing the wavelet conversion of a detection signal corresponding to the properties of a material to be inspected and hence preventing the non-detection and excessive detection of a defect. SOLUTION: Light reflected from the steel plate of a material to be inspected is detected by an optical sensor 1 and a leaked magnetic flux is detected by a magnetic sensor 2. A signal with both polarities detected by the sensors 1 and 2 is filtered by filters 3 and 4 and cleared of a certain amount of noise. The detected signal with both polarities and both filter signals are subjected to wavelet conversion by k different scale parameters using wavelet WT conversion circuits 5 and 6. Signal processing circuits 7 and 8 generate an image suited for detecting a defect from k images which are subjected to wavelet conversion and give it to a defect judging circuit 9. The circuit 9 obtains the amount of feature (for example, area and size) based on the generated image, thus judging the type and class of the defect.
