Abstract
A timer including a sensor and a radiation source is used to prevent counterfeiting of integrated circuits. The timer confirms the date code of the integrated circuit resulting in a more secure supply chain.
Claims20
An integrated circuit chip to prevent counterfeiting, comprising:
- a timer device comprising a radiation source component and a sensor component, wherein the sensor component detects an activity level of the radiation component to internally verify a date code stamped on the integrated circuit chip;
- a radiation-proof shield covering both the radiation source component and the sensor component;
- and
- a counter or a multimeter or a voltmeter interfacing with the timer device via a spare pin of the integrated circuit chip.
