METHOD FOR MANUFACTURING AN INTEGRATED CIRCUIT HAVING A PARTICULAR FUNCTIONALITY REQUIRED BY A USER OF THE CIRCUIT AND HAVING FIRST STRUCTURES TO PRODUCE THE PARTICULAR FUNCTIONALITY AND SECOND STRUCTURES

摘要

An integrated circuit has first structures that are produced in a plurality of wiring planes using exposure masks and serve for producing a functionality required by the user of the circuit. The circuit also has second structures that are produced in a plurality of the wiring planes using the exposure masks and do not serve for the particular functionality, but rather for the capability of checking if the exposure masks used belonged to a common mask set.
