Abstract
A method of manufacturing a metal layer structure and a corresponding integrated circuit chip are provided, wherein the integrated circuit chip comprises metal layers and via holes. The via holes electrically connect a metal line of one metal layer with a metal line of another metal layer. The metal lines and via holes form a signal path that electrically connects a first tap with a second tap. The metal lines in each metal layer are arranged in a first predefined configuration. There is for each metal layer a second predefined configuration that arranges the metal lines in the metal layer to form, together with the via holes and the metal lines in the other metal layers, a modified signal path that electrically connects the first tap with a third tap. This technique is particularly useful for storing revision identification data.
