Title: Abrasive, polishing method, and manufacture of semiconductor device
Inventor: KISHII SADAHIRO
IPC: B24D3/02
Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To suppress the erosion of a polished metallic material by an abrasive composed of MnO2 abrasive grains, a solvent, and an additive agent and, at the same time to improve the selectivity of the abrasive against an insulating film by adding a benzene ring to the additive agent. SOLUTION: An abrasive is prepared by mixing MnO2 abrasive grains, a solvent, and an additive agent together. Potassium phthalate is used as the additive agent. A W layer and an SiO2 layer formed on a substrate are polished with the abrasive. The abrasive selectively acts on the W layer constituting a conductor layer 4 and the polishing spontaneously stops when the upper main surface of an insulating film 3 is exposed. When the surface becomes flat as a result of such polishing, the upper main surface of a conductor plug 4b is flushe with the upper main surface of the insulating film 3. Since the MnO2 contained in the abrasive as abrasive grains works as a solid oxidizing agent, the polishing is limited to the surface of the plug 4b on which the abrasive grains actually act and a seam in the plug 4b is not eroded at the polishing time.

Filed: 1983-09-16
Abstract: PURPOSE:To simplify the constitution of an optical disk reproducer by flowing the current to >=2 coils set to a lens holder in order to drive a part to be driven including an objective lens in two or three directions. CONSTITUTION:A cylindrical coil 23 is wound around a bobbin 22, and a semi- cylindrical flat square coil 24 is welded to the outer circumference of the coil 23. A holder 16 is welded at the upper end part of the bobbin 22, and an objective lens 15 is held at the center of the holder 16. A permanent magnet 20 is magnetized in the direction Z, and a plate 19 and a pole piece 21 are fixed on both energized surfaces of the magnet 20 to form two magnetic gaps. A damper 17 is attached to the bobbin 22 and a supporter 18 respectively so that a part where both coils 23 and 24 are set orthogonal to each other is set into said magnetic gap. When a current is flowed to the coil 23, the lens 15 is driven toward the direction Z by an interaction between the gap and a magnetic flux. While the lens 15 is driven toward X by the same interaction when a current is flowed to the coil 24.

Filed: 1982-09-29
Abstract: PURPOSE:To improve light efficiency by forming a photodetection side of a bundle of bulk fibers having a large diameter and a projection side of a bundle of bulk fiber having a small diameter. CONSTITUTION:The 1st optical fiber 4 on the photodetection side consists of the bundle 19 of 25 bulk fibers 18 having, for example, a 2mm. diameter and the 2nd optical fiber 15 on the projection side consists of the bundle 16 of 277 bulk fibers 17 having a 1mm. diameter; the 1st optical fiber is wired to the vicinity of a lighting equipment 8 and its projection side is connected to the incidence end of the 2nd optical fiber 15.

Title: Method for turning over thick plate
Inventor: AOKI MASAHIRO
IPC: B21B39/20
Filed: 1992-06-29
Abstract: PURPOSE:To reduce slippage between a thick plate and each table roll and to enable the thick plate to be smoothly and rapidly turned over by turning over the thick plate under control of the rotational speed of each roll so that the angular speed of the thick plate is nearly constant. CONSTITUTION:Since the profile of the table roll 12 is made arcuate, the contact between the thick plate 20 and each table roll 12 shows a point contact and the slippage between the thick plate 20 and the table roll is reduced. Further, since the rotational speed of each roll 12 is controlled in response to a distance from the center of turning of the thick plate 20 so that the angular speed of the thick plate is made nearly constant when the thick plate 20 is turned over, the slippage between the thick plate 20 and the table roll 12 is reduced further and the thick plate 20 can be smoothly and quickly turned over. In particular, when each roll 12 is made capable of being shifted in its axial direction and the axial position of each roll 12 is controlled so that the respective contact points of the rolls with the thick plate 20 are arranged nearly on a circle before turning over the thick plate 20, the thick plate 20 can be turned over more smoothly.

Abstract: PURPOSE:To enable correction by the accurate positional alignment of a defect section by a method wherein an X-ray mask with a protective film is irradiated with focussed ion beams and the protective film is removed, a defect-section circuit pattern is exposed, the position of the defect is detected, focussed ion beams are applied and the defect section is corrected. CONSTITUTION:The upper section of an X-ray mask 200 is irradiated with ion beams, but a defect is not displayed onto a display 509 owing to a protective film on a pattern. A region in which there is a defect is detected by using a transmission type electron microscope, etc., a slightly wider region is scanned and worked by ion beams, a circuit pattern 205 is detected by the scanning ion image of a detector 508 when the circuit pattern 205 in a lower layer is exposed, and a defect section is aligned with high precision. Even currents to a plating electrode 203 can be detected besides the detection of secondary electrons and secondary ions from an X-ray mask at that time. Since working suddenly progresses in exposed Au having a high sputtering rate in this case, a metal 206 having a low sputtering rate such as Ta, W, etc. is formed thinly as the stopper of etching through plating, etc.
