Abstract:
1. A method for fabricating an interconnection of active and passive components provided with terminals for their interconnection, comprising the steps of: thinning the passive components; positioning and fixing the active and passive components on a flat support, the terminals being in contact with the support; depositing a polymer layer on all of the support and the components; removing the support; rectifying and pre-thinning the polymer layer to calibrate the thickness of the layer to a predetermined value and render the surface of said layer substantially flat and parallel to the support; redistributing the terminals between the components and/or toward the periphery by means of metal conductors arranged in a predetermined layout, to obtain a reconstituted heterogeneous structure; and thinning the structure by nonselective surface treatment of the polymer layer and at least one passive component; and wherein, the passive component is a ceramic capacitor with a zone of even and odd interdigitated electrodes, two ceramic filling zones on either side of the electrode zone and two lateral end terminals to which the even and odd electrodes are respectively connected, the prior thinning step consists in thinning on one of its faces perpendicular to the plane of the electrodes.
