Wafer for electronic chip manufacture has electronic chips and memory device with stored classification map with position and classification information for at least one part of chip

摘要

The device has electronic chips and a memory device with a stored classification map with position and classification information for at least one part of the chip. The position information gives the position of each chip on the wafer and the classification information gives a classification of each chip in accordance with a given criterion. An independent claim is also included for a wafer manufacturing method.
