CHIP SECURITY DETECTION METHOD, CHIP STRUCTURE AND CHIP MODULE

摘要

A chip security detection method. The chip at least comprises an integrated circuit, and a metal layer covering the integrated circuit. The method comprises: building a current loop on a metal layer; setting a signal generator, a signal receiver and a determination circuit in the integrated circuit; the signal generator outputting a specific signal, and the specific signal being input into the current loop; the current loop converting the specific signal into a detection signal, receiving the detection signal via the signal receiver and inputting the detection signal into the determination circuit; and the determination circuit determines whether the chip has a security risk according to the detection signal and the specific signal. In the chip security detection method, a current loop converting a specific signal into a detection signal, and then determining whether an abnormality occurs by comparing the detection signal with the specific signal, and therefore, a chip can be prevented from sustaining an unpredictable risk due to a damaged external factor.
