Abstract:
1. A microelectronic assembly, comprising: a substrate having first and second opposed surfaces, substrate contacts at the first surface, and terminals at the second surface electrically connected with the substrate contacts; a first microelectronic element having contacts at a front face thereof facing the substrate contacts and joined thereto; a second microelectronic element overlying the first microelectronic element and having contacts at a front face facing away from the substrate; a lead frame having lead fingers, each of the lead fingers comprising a body having a top surface and a bottom surface, wherein the second surface and the bottom surface of the lead fingers define a common interface for electrical interconnection to a component external to the microelectronic assembly, at least a portion of the lead fingers overlying the first surface of the substrate; electrical connections extending between the contacts of the second microelectronic element and the lead fingers; and an encapsulant overlying the electrical connections, the first and second microelectronic elements, the substrate and at least portions of the lead fingers, wherein the second surface and the bottom surface are coplanar and extend along a common plane parallel to a plane along which the front face of the first microelectronic element extends, the common interface being formed along the plane.
