Naked microelectronic chip provided with a slot that forms a housing for a filar element constituting a flexible mechanical support, manufacturing process and microstructure

摘要

Microelectronic chip (1) that includes an electrically conductive filar element (10,11), two main front and rear parallel faces (4, 5), side faces (6, 7) and a recess forming a housing for the electrically filar element conductor (10, 11), the recess being a groove placed on one of the main or side faces, the groove having an axis parallel to the main faces for a fastening fixation of the electrically conductive filar element (10, 11) in said groove , the chip being provided with at least one electrical connection element intended to connect a microelectronic component integrated in the chip with the wire element, the electrical connection element being, in the case of a groove placed on a side face, at least partly constituted by an electrically conductive layer that at least partially covers said groove; chip characterized in that the insertion of the electrically conductive filar element (10, 11) in said slot follows the longitudinal axis of the latter, said electrically conductive filar element (10, 11) constituting a flexible mechanical support for said chip.
