Title: Method and apparatus for inspecting semiconductor wafer
Inventor: YAMAGUCHI ZENZO
IPC: G01N21/88
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To lighten inspector's burden while maintaining uniform accuracy, by judging whether a semiconductor wafer is good or defective through automatic inspection based on an image of the semiconductor wafer, and carrying out a visual inspection for the semiconductor wafer judged as defective. SOLUTION: One wafer 10 is taken out by a robot and moved to immediately below a CCD camera 11. When the wafer 10 is detected by a wafer invasion sensor 16, an image-processing device 12 starts an inspection in response to a signal. First, the CCD camera 11 takes in an image of the wafer 10 and sends to the image- processing device 12. The image-processing device 12 digitizes the image with a predetermined gradation, binarizes with a suitable threshold value whereby a defective part and the other part can be distinguished from each other, and obtains a count of pixels of a part that can be recognized as a defect, thereby judging the wafer of the pixel count exceeding a predetermined value as a defective product and one of the pixel count not larger than the predetermined value as a good product.  The wafer 10 which is judged to be defective in the automatic inspection is visually inspected by an inspector. Accordingly, the inspection is carried out with uniform accuracy without variations and only defective product can be correctly removed.
