Title: Cerium oxide abrasive agent and polishing method of substrate
Inventor: YOSHIDA MASATO
IPC: B24B37/00
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To evenly polish the surface of an SiO2 insulating film or the like by a method where cerium compound hydrate is burned at a specific temperature as air and/or oxygen gas is introduced at a specific temperature and linear velocity, and the cerium oxide particle obtained by burning is dispersed into dispersion medium for the formation of slurry. SOLUTION: Cerium compound hydrate is burned at temperatures of 400-900 deg.C as air and/or oxygen gas is introduced at a linear velocity of 1cm/min or above, keeping an atmosphere around cerium oxide particle uniform, so as to obtain homogeneous cerium oxide particle. The obtained cerium oxide powder is dispersed into a dispersion composition (medium) composed of water and dispersing agent, as required, so as to obtain slurry. An SiO2 insulating layer is polished with cerium oxide abrasive agent (slurry), then its rough surface is made flat throughout all the surface of the semiconductor substrate.

Abstract: PURPOSE:To enable a light-emitting unit to be compact without reducing the size of an illumination area of a flux of light which is effective for detection by making a collimater lens within a light-emitting unit to be rectangular. CONSTITUTION:Light which is emitted from a light source LD becomes a parallel light by a collimater lens CL, where the collimater lens CL is of a rectangular shape with an effective are including an effective flux of light of a rectangular shape which is subjected to photoelectric conversion by a light-receiving unit RL.

Filed: 1990-09-28
Abstract: PURPOSE:To absorb a noise charge mixed in a charge detection section by connecting the charge detection section to a low impedance source at a rising period and a falling period of an electronic shutter pulse. CONSTITUTION:An original reset pulse SR 1 is fed from a 1st timing generator(TG) 25 to an OR circuit 28. A 2nd TG applied a gate pulse SG going to a high level at least for a period including a rising and a falling period of an electronic shutter pulse SP based on a horizontal synchronizing pulse SH and the original reset pulse SR 1. Thus, an output of the OR circuit 28 is fed to a reset gate 8 as a new reset pulse SR similar to the original pulse SR 1. A gate circuit 23 is closed and turned on when the reset pulse SR is at a high level to short-circuit a power supply VDD and a charge detection section 6. Thus, even when noise charge is going to be stored in the charge detection section 6, the charge is absorbed by the power supply VDD through the gate circuit 23.
