Manufacturing managing method of semiconductor devices and a semiconductor substrate

Abstract

A managing method of manufacturing semiconductor devices is disclosed. The method comprises the steps of: providing at least one tag region on a semiconductor substrate in which plural semiconductor devices have been formed, the tag region being provided with a tag which can read/write information without making physical contact; writing manufacturing managing information of each of the semiconductor devices into the tag without making contact with the semiconductor substrate; and reading the manufacturing managing information from the tag after dividing the semiconductor substrate, and selecting non-defective semiconductor devices based on the manufacturing managing information.
