Abstract
A microelectronic package has a microelectronic element overlying or mounted to a first surface of a substrate and substantially rigid conductive posts projecting above the first surface or projecting above a second surface of the substrate remote therefrom. Conductive elements exposed at a surface of the substrate opposite the surface above which the conductive posts project are electrically interconnected with the microelectronic element. An encapsulant overlies at least a portion of the microelectronic element and the surface of the substrate above which the conductive posts project, the encapsulant having a recess or a plurality of openings each permitting at least one electrical connection to be made to at least one conductive post. At least some conductive posts are electrically insulated from one another and adapted to simultaneously carry different electric potentials. In particular embodiments, the openings in the encapsulant at least partially expose conductive masses joined to posts, fully expose top surfaces of posts and partially expose edge surfaces of posts, or may only partially expose top surfaces of posts.
