Abstract:
1. An interconnection structure having upper and lower surfaces extending in horizontal directions and edges extending between the upper and lower surfaces, the interconnection structure comprising: electrically conductive elements at the lower surface; a dielectric mass defining a top surface remote from and facing away from the lower surface, the dielectric mass defining a first edge surface extending downwardly from a top border adjacent the top surface of the dielectric mass to a bottom border interior of the edges, the dielectric mass further defining an upwardly-facing flange surface extending away from the bottom border of the first edge surface in a horizontal direction, the flange surface being disposed at a vertical distance from the lower surface less than a vertical distance between the lower surface and the top surface of the dielectric mass; a plurality of top terminals exposed at the top surface of the dielectric mass; a plurality of traces extending from the top terminals along the top surface and extending along the first edge surface, the traces having bottom portions extending along the flange surface; and a plurality of electrically conductive via connectors extending through the flange surface of the dielectric mass and electrically connecting the bottom portions of the traces with the conductive elements at the lower surface.
