Abstract
A stack including a dual-passivation is etched locally so as to reveal contact pads of an integrated circuit which are situated above a last metallization level of an interconnection part of the integrated circuit. This stack serves to protect the integrated circuit against a breakdown of at least one dielectric region, at least in part porous, separating two electrically conducting elements of the interconnection part of the integrated circuit. Such a breakdown may occur due to electrical conduction assisted by the presence of defects within the at least one dielectric region.
