The assembly comprises at least one microelectronic chip having two parallel main surfaces and lateral surfaces, at least one of the lateral faces comprising a longitudinal groove housing a wire element having an axis parallel to the longitudinal axis of the groove. The groove is delineated by at least two side walls. The wire element is secured to the chip at the level of a clamping area between at least one bump arranged on one of the side walls, and the side wall of the groove opposite said bump. The clamping area has a smaller height than the diameter of the wire element and a free area is arranged laterally to the bump along the longitudinal axis of the groove. The free area has a height, corresponding to the distance separating the two side walls, that is greater than the diameter of the wire element.

Assembly of at least one microelectronic chip with a wire element, the chip comprising a groove for embedment of the wire element. The wire element is a strand with a longitudinal axis substantially parallel to the axis of the groove, comprising at least two electrically conducting wires covered with insulator. The chip comprises at least one electrically conducting bump in the groove, this bump being in electric contact with a stripped area of a single one of the electrically conducting wires of the strand.

A reconstituted electronic device including: a first face and a second face; a plurality of individual chips placed perpendicular to the faces, each individual chip carrying, on one of its surfaces, at least one component, tracks, and a connection mechanism that are flush with one or other of the faces of the reconstituted electronic device; and an encapsulant that encapsulates the individual chips.
