Abstract
A microelectronic package and method of making same are provided. The package includes a substrate having first and second opposed surfaces, an edge surface extending therebetween, a plurality of terminals, and a plurality of conductive elements electrically connected with the terminals. The edge surface can be disposed at a periphery of the substrate or can be the edge surface of an aperture within the substrate. A microelectronic element has a front face and contacts thereon, with at least some of the contacts being adjacent to the edge surface of the substrate. A dielectric material overlies the edge surface of the substrate and defines a sloping surface between the front face of the microelectronic element and the substrate. A conductive matrix material defines a plurality of conductive interconnects extending along the sloping surface. The conductive interconnects electrically interconnect respective ones of the contacts with the conductive elements.
