Patent ID: 8581251

Claim:
An electronic integrated circuit comprising an electronic chip ( 1 ) attached to a substrate ( 3 ), the assembly being protected by a housing, the electronic chip being provided with input/output studs ( 2 ) connected to linking pads ( 6 ) arranged on the substrate, this circuit being further provided with at least one ingression detection means ( 9 , 10 ) capable of detecting a mechanical and/or chemical ingression inside the housing and/or an attempt to access a sensitive area of the integrated circuit, characterized in that said ingression detection means ( 9 , 10 ) comprises a detection circuit ( 9 ) embedded in the substrate and/or placed at a different location on the substrate ( 3 ) from that of the integrated circuit, and arranged so as to pass in the immediate vicinity of some sensitive areas of the integrated circuit so that any attempt to access any one of said sensitive areas brings about a change in the electric state (closed/open) of said detection circuit ( 9 ).
