1. Electronic device comprising an electrical interconnection structure forming at least one electrical conduction path between at least two points of the electronic device and/or at least one electrically conducting plane, and comprising an alternating stack of arrays of conducting lines and dielectric layers in which:
- all the conducting lines of a same array extend in a same plane and form an equipotential;
a first pattern of the conducting lines of a first array is such that at least one first of the conducting lines of the first array extends along at least one first direction and several second of the conducting lines of the first array intersect the first of the conducting lines of the first array at several intersections;
a third pattern of the conducting lines of a third array is similar to the first pattern, the first and third patterns being superimposed one on top of the other and such that the intersections of the first pattern are aligned with intersections of the third pattern along an axis substantially perpendicular to the planes in which the conducting lines of the first and third arrays extend;
a second pattern of conducting lines of a second array arranged between the first and third arrays of conducting lines is such that at least one first of the conducting lines of the second array extends along the first direction and several second of the conducting lines of the second array intersect the first of the conducting lines of the second array at several intersections offset with respect to the intersections of the first and third patterns;
at least one first conducting via extends through at least one part of at least one of the dielectric layers interposed between the first and third arrays of conducting lines, is in contact with at least one of the conducting lines of the first array and/or of the third array and is such that a section of the first conducting via projected in a plane in which the conducting lines of the second array pass is not in contact with the conducting lines of the second array.

Abstract
Electronic device comprising an interconnection structure comprising an alternating stack of arrays of conducting lines and dielectric layers in which:
- all the lines of a same array extend in a same plane and form an equipotential;
- a first pattern of a first array is such that the lines of the first array intersect at several intersections;
- a third pattern of a third array is similar, superimposed and aligned with the first pattern;
- a second pattern of a second array arranged between the first and third arrays is such that the lines of the second array intersect at several intersections offset with respect to those of the first and third patterns;
- a first conducting via extends from a line of the first and/or third array and is not in contact with the second array.
