摘要

A packaged microelectronic assembly includes a microelectronic element (104) having a front surface (122) and a plurality of first solid metal posts (110) extending away from the front surface (122). Each of the first posts (110) has a width in a direction of the front surface (122) and a height extending from the front surface (122), wherein the height (H2) is at least half of the width (Wl). There is also a substrate (102) having a top surface (101) and a plurality of second solid metal posts (108) extending from the top surface (102) and joined to the first solid metal posts (110).
