Claim:
1. A microelectronic package comprising: a first substrate having a first surface, a second surface remote from the first surface, a plurality of first substrate contacts exposed at the first surface, and a plurality of terminals electrically interconnected with the first substrate contacts and exposed at the second surface; a second substrate remote from the first substrate, the second substrate having a first surface facing towards the first surface of the first substrate, a second surface remote from the first surface, a plurality of second substrate contacts exposed at the second surface of the second substrate; a microelectronic element disposed between the first surface of the first substrate and the first surface of the second substrate, the microelectronic element having a first face, a second face remote from the first face, and element contacts exposed at the first face, one of the first or second faces facing towards the first surface of the first substrate and another one of the first or second faces facing towards the first surface of the second substrate; electrically conductive structure coupling electrically conductive elements on each of the first and second substrates; a continuous encapsulant overlying the first surface of the first substrate, the electrically conductive structure, and at least a portion of the second surface of the second substrate, the continuous encapsulant defining a major surface and openings extending downwardly from the major surface; and a plurality of package contacts exposed at the major surface of the encapsulant and overlying the second surface of the second substrate, the package contacts projecting above a height of the second substrate contacts at least partly within the openings in the encapsulant, the package contacts being electrically interconnected with the element contacts of the microelectronic element through at least the electrically conductive structure, the package contacts including solid metal posts having frusto-conical shape of copper or gold projecting upwardly from the second surface of the second substrate, wherein at least top surfaces of the package contacts are at least partially exposed at the major surface of the encapsulant.
