Filed: 1989-04-18
Abstract: PURPOSE:To make it possible to identify a foreign matter at the position of a special mark by specifying a detected voltage as effective or invalid in accordance with the effective conditions or the invalid conditions for preset coordinate position for each detecting area. CONSTITUTION:Classifying voltages V1 - V4 are imparted to a signal processing part 7 from an input/output part 11 by the control of a microcomputer 9. The effective conditions and the invalid conditions and the coordinates of special marks are stored in a memory 10 for each detecting region. Here, the classifying voltages and the effective or invalid conditions are adequately determined based on the data in experiments. In the inspection of foreign matters, the detected voltages from a pattern detector 6a and a foreign matter detector 6b are inputted into the signal processing part 7. The voltages are allocated into the corresponding detecting sections. The conditions stored in the memory are set at a switch 8 for the coordinate position of the special mark. The detected voltage under the effective conditions is transferred into the processor 9. When the voltage is under the invalid condition, the voltage is not transferred. In this way, the foreign matter at the position of the special mark can be identified.
