Patent abstract
A method and tamper detection circuit for implementing tamper and anti-reverse engineering evident detection in a semiconductor chip, and a design structure on which the subject circuit resides are provided. A capacitor is formed with the semiconductor chip including the circuitry to be protected. A change in the capacitor value results responsive to the semiconductor chip being thinned, which is detected and a tamper-detected signal is generated.
