Electronic module, method for manufacturing same and electronic device comprising a module of said type
The invention relates to an electronic module comprising a dielectric support film having a first side, conductor paths that are printed on said first side, and a semiconductor component which connects the conductor paths by means of electrical connections. The electronic module of the invention is characterized in that each electrical connection includes a lead wire that connects a contact of the semiconductor component to each path directly or via an island or an interconnection pad.
1. A method of manufacturing an electronic module comprising a dielectric support film bearing conductor paths and a semiconductor component connected to the conductor paths, wherein said method comprises:
a stage of printing conductive material to form conductor paths on a first side of the dielectric support film by means of a process involving printing said conductor paths directly on the dielectric support film using a conductive ink or conductive material; and
transfer and connection of a contact of a semiconductor component, which is provided on the first side of the dielectric support film, to the conductor paths by means of lead wires, wherein one or more of said lead wires directly connects one or more contacts of the semiconductor component to the conductive ink or conductive material printed to form one or more of said conductor paths.
2. The method according to claim 1 , further comprising a prior stage involving assembling a metallised layer on a second side of the dielectric support film, creating several electrical contact pads in said metallised layer and electrically connecting said semiconductor component to said electrical contact pads.
3. The method according to claim 1 , wherein a second end of each conductor path is created on a surface so as to form an interconnection pad designed to be electrically connected to an interconnection terminal of an electric circuit.
4. The method according to claim 1 , wherein each end of each lead wire is fixed on the one hand to a contact stud of the semiconductor component and on the other hand to an electrical contact island, a contour of which is previously marked out in a contact pad, passing through a reservation formed in a thickness of the dielectric support film with respect to said electrical contact island, so that it electrically connects said contact stud of the semiconductor component to said electrical contact island and wherein a first end of each conductor path to be connected is printed on a surface of said electrical contact island in said reservation and emerges on a side of the dielectric support film bearing said semiconductor component.
5. The method according to claim 1 , wherein the conductor paths are printed using one of the following methods: inkjet, spray, LIFT, silkscreen printing, flexography or photoengraving.
