Abstract
A microelectronic assembly includes a substrate having a first surface, a plurality of first conductive pads exposed thereon, and a plurality of first metal posts. Each metal post defines a base having an outer periphery and is connected to one of the conductive pads. Each metal post extends along a side wall from the base to ends remote from the conductive pad. The assembly further includes a dielectric material layer having a plurality of openings and extending along the first surface of the substrate. The first metal posts project through the openings such that the dielectric material layer contacts at least the outside peripheries thereof. Fusible metal masses contact the ends of some of first metal posts and extend along side walls towards the outer surface of the dielectric material layer. A microelectronic element is carried on the substrate and is electronically can be connected the conductive pads.
