Patent ID: 6927095

Claim:
A method of making a microelectronic package comprising: providing a first substrate having a top surface; providing a second substrate having a top surface including a plurality of conductive pads, a bottom surface remote therefrom and an opening extending between the top and bottom surfaces, and attaching said second substrate to said first substrate so that the bottom surface of said second substrate confronts the top surface of said first substrate; placing a microelectronic element having a front face with contacts and a back face remote therefrom in the opening of said second substrate and securing said microelectronic element to said first substrate so that the back face of said microelectronic element confronts the top surface of said first substrate; electrically interconnecting the contacts of said microelectronic element with the conductive pads of said second substrate; juxtaposing a dielectric sheet having conductive leads with said second substrate, said conductive leads having first ends permanently attached to said dielectric sheet and second ends opposite the first ends; electrically interconnecting the second ends of said leads to the conductive pads of said second substrate so as to electrically interconnect said leads with said contacts of said microelectronic element; and moving said dielectric sheet and said second substrate away from one another so as to vertically extend said leads between said dielectric sheet and said second substrate.
