An identification circuit including an assembly of Wheatstone bridges and comparators is formed in a substrate. Since the resistors forming the bridges are sensitive to technological dispersions, the output voltages of the bridges are not identical. Each comparator compares the outputs of two bridges and provides a bit of an identification number of the chip. Preferably, the resistors are covered with insulator only, at least up to a second interconnect level from the substrate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Integrated circuit chip identification element","description":"Wheatstone bridges, each formed of four identical resistors, are used as integrated circuit identification elements.
