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 8):
A method, comprising:\n forming an underlying substrate region under an insulation region in a semiconductor substrate; forming transistor components in and on the semiconductor substrate; depositing an etch-stop layer covering protruding parts of the transistor components; depositing a pre-metallization dielectric layer over the etch-stop layer; etching through the pre-metallization dielectric layer and etch-stop layer to form first and second openings which further extend through the insulation region to reach the underlying substrate region and to form third openings to reach terminals of the transistor components; and filling the first, second and third openings with a metal material.
