Filed: 1983-11-11
Abstract: PURPOSE:To allow characters printed on the surface of a wafer to be read out with cost and accuracy even after being subjected to physical change by revising electrical signals obtained by photographying the said characters by use of a difference between a piece of read information at a specified position on the surface of the wafer and a piece of reference information memorized in advance. CONSTITUTION:If a reference pattern A has been written on the whole surface of a semiconductor wafer near characters in writing the characters to be originally read, the reference pattern A keeps the same printed surface state as the characters to be originally read. By memorizing a position of the reference pattern and a piece of read information A' of the reference pattern A before production processing of IC, a difference C' between a piece of read information B' in reading a reference pattern B varied by processing and the piece of read information A' of the reference pattern A is obtained. This difference represents a difference between the printed surface before production processing of IC and that at the time point of reading. Accordingly, if a piece of read information of the characters to be originally read is revised by the said difference C', the printed surface state of the pattern A before production processing of IC can be reproduced.
