SEMICONDUCTOR INTEGRATED CIRCUIT PROVIDED WITH IDENTIFYING FUNCTION

摘要

PURPOSE: To make it possible to individually judge the acceptability of the electrical functions of chips, by providing them with a fuse element for storing information therefor. CONSTITUTION: A plurality of semiconductor integrated circuit (IC/LSI) chips 2 are formed in a matrix on a silicon wafer 1. These IC/LSI chips 2 are divided by scribed lines 3. There are two sections in each chip 2: A device circuit section 4 where functions as an IC are to be provided, and an identification information storing section 5 where an element for storing chip identification information is to be formed. The device circuit sections 4 and the chip identification information storing sections 5 are electrically isolated from each other. This obtains a semiconductor integrated circuit provided with an identifying function that makes it possible to individually judge chips, and that is helpful to the rationalization of assembling processes and defect analyses.
