Title: Brush cleaning method in brush scrubbing process
Inventor: YAMAZAKI TOSHIYUKI
IPC: H01L21/304
Filed: 1993-05-18
Abstract: PURPOSE:To prevent a wafer from being inversely contaminated by a brush again by a method wherein all detergent is discharged from a brush cleaning tank after a brush is cleaned, and new detergent is supplied. CONSTITUTION:A rotating brush 1 is pressed against the surface of a semiconductor wafer 31 to clean it as detergent 3 is sprayed on the rotating brush 1. Thereafter, the brush 1 is wetted with detergent 3 in the brush cleaning tank 2 to be cleaned as it is rotated. After detergent 3 is discharged from the brush cleaning tank 2, and new cleaning liquid 3 is fed into the brush cleaning tank 2. By this setup, particles attached to a brush by cleaning a wafer are discharged into detergent in a brush cleaning tank. Detergent in a brush cleaning tank is all replaced after a brush cleaning operation is finished, so that particles are not left in a brush cleaning tank, and detergent is kept clean in a brush cleaning tank.

Title: Method for inspecting inside of glass
Inventor: HORIBATA OSAMU
IPC: G01N21/896
Filed: 1987-06-05
Abstract: PURPOSE:To perform inspection accurately without utilizing the state of a surface, by projecting light at a slant angle from the lower side, under the state glass is immersed in a liquid having approximately the same reflectivity as that of the glass, and inspecting the glass with a microscope. CONSTITUTION:Glass is immersed into a liquid, which has approximately the same reflectivity as that of the glass to be inspected, such as polyethylene glycol and amyl alcohol for quartz glass. Even if the surface of the glass becomes a satin state and irregular reflection occurs or the surface is in a mirror surface state, the inside of the glass can be observed almost at the same degree. The interface of the glass in the liquid is hard to see. In order to eliminate the effect of a container especially, it is desirable to increase the amount of the liquid and to place the glass to be inspected at a position separated farther from the wall surface of the container. Under this state, light is projected at a slant angle from the lower side of the glass to be inspected. The reflected light is confirmed through a microscope. In this way, foreign materials, bubbles and the like in the inside of the glass to be inspected can readily be recognized.

Abstract: PURPOSE:To detect accurately a scene change by adding the evaluated results of the motion compensation forecasting error in plural lines and comparing the addition result with a determined threshold. CONSTITUTION:A variable delay circuit 13 delays variably the picture signal of one picture before outputted from a frame memory 12 in accordance with a dynamic vector supplied through a line 113 and outputs the signal to a subtractor 14 as a motion compensation forecasting value. The subtractor 14 subtracts the motion compensation forecasting value from the delayed input signal supplied through a line 1814 to obtain the motion compensation forecasting error. An absolute value calculator 15 calculates the absolute value of the motion compensation forecasting error and outputs it to an integrating circuit 16. The integrating circuit 16 adds the motion compensation forecasting error from the start of a frame and outputs the result to a comparator 17. When the addition result exceeds the preliminarily determined threshold, the comparator 17 discriminates the scene change to output 1 to an output terminal 2000.
