Title: Chemo-mechanical polishing method of wafer
Inventor: IDE SATORU
IPC: B24B37/30
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent generation of a cloud by etching on the surface of a polished wafer by forming a thin film of pure water between the installing surface and the wafer surface by the pure water supplied to the installing surface during wafer polishing on the wafer installing surface of a chuck mechanism for sucking a wafer. SOLUTION: A valve 13 is opened in the middle of rough polishing and finish polishing of a wafer, pure water is supplied from a pipe 14, and the pure water having pressure slightly higher than infiltration pressure is supplied so that abrasive slurry does not infiltrate into clearance between the wafer (w) and the installing surface of a chuck mechanism to form a thin continuous film of the pure water in this clearance. Since supplied water happens to reduce a polishing speed by diluting the concentration of the abrasive slurry by oozing out to the platen side, water pressure must not be excessively increased by reducing an oozing quantity. Supply of pure water and a cleaning liquid in a hollow shaft 4 is useful for washing away polishing chips and an abrasive grain clogged in a small hole of a sucking plate 6, so that a cloud is not generated on the wafer chuck surface.

Title: Autofocusing projector
Inventor: TSUKADA TOSHIRO
IPC: G02B7/28
Filed: 1988-12-26
Abstract: PURPOSE:To improve accuracy without using a mirror and to make a range- finding optical system simple and compact by using results obtained by measuring the tilt angle of the mirror and a distance to a screen where an image is projected so that the difference of projection distance from the mirror to the screen is corrected and performing the autofocusing of a projecting lens. CONSTITUTION:The projecting lens 10 enlarges the image and a distance sensor 20 measures the distance to the screen where the image is projected without using the mirror 11. A detection means 13 converts the tilt angle of the mirror 11 into an electrical signal. A processing means corrects the projection distance from the results obtained by measuring the angle of the mirror and the distance and performs the autofocusing of the projecting lens 10. Therefore, the reflection of the signal of light, etc., by the mirror need not be used in order to measure the distance. Thus, the distance to the screen is measured without using the mirror when it is measured and the accurate autofocusing of the projecting lens is performed based on the distance to the screen surface, thereby making the range-finding optical system compact.

Filed: 1990-11-27
Abstract: PURPOSE:To prevent circuit scale from being unnecessarily increased by forming arbitrary resolution not to be restricted by resolution for the unit of a bit in the D/A converter circuit. CONSTITUTION:The couple of a prime number (p), natural number (q) and characteristic function g(s)epsilon{p-1, p} (s=0, 1... q) exists while satisfying an expression I and by constituting a D/A converter in the manner of the pseudo p-adic of an expression II, the D/A converter can be formed with the arbitrary output resolution. For example, assuming that control signals D0(t), D2(t), D3(t) and D+(t) are at an H level and all the remaining signals Ds(t) are at an L level, the switches of blocks B0, B2 B3 and B+ are turned on and the switches of the remaining blocks are turned off as the result. Therefore, IA, 4IA, 8IA and 16IA are respectively outputted from the blocks B0, B2, B3 and B+ and no constant current flows from the remaining blocks. Therefore, the total current supplied onto an output line is 29IA, this current is supplied as an output analog signal A and the circuit scale can be reduced.
