Abstract:
The thinning of a semiconductor substrate of an integrated circuit from a back face is detected using the measurement of a physical quantity representative of the resistance between the ends of two electrically-conducting contacts situated at an interface between an insulating region and an underlying substrate region. The two electrically-conducting contacts extend through the insulating region to reach the underlying substrate region.

Claim (Index 13):
A method for detecting a thinning of an integrated circuit semiconductor substrate of an integrated circuit from its back face, comprising:\n forming within the integrated circuit semiconductor substrate a well region that exhibits a resistance between a first electrical contact to the well region and a second electrical contact to the well region, said resistance being dependent on a thickness of the well region; measuring a voltage drop between the first and second electrical contacts that is indicative of the resistance; comparing the measured voltage drop to a reference voltage; and indicating that thinning of the integrated circuit semiconductor substrate has occurred if the measured voltage relative to the reference voltage changes due to change in thickness of the well region.
