A microelectronic package includes a microelectronic element having faces
and contacts and a flexible substrate spaced from and overlying a first
face of the microelectronic element. The package also includes a
plurality of conductive posts extending from the flexible substrate and
projecting away from the first face of the microelectronic element,
wherein at least some of the conductive posts are electrically
interconnected with the microelectronic element, and a plurality of
support elements supporting the flexible substrate over the
microelectronic element. The conductive posts are offset from the support
elements to facilitate flexure of the substrate and movement of the posts
relative to the microelectronic element.
