Abstract:
1. 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 securing said second substrate over said first substrate so that the bottom surface of said second substrate confronts the top surface of said first substrate, wherein said first and second substrates have coefficients of thermal expansion that are substantially similar to one another; 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 over said first substrate so that the back face of said microelectronic element confronts the top surface of said first substrate; and electrically interconnecting the contacts of said microelectronic element with the conductive pads of said second substrate by attaching first ends of a plurality of conductive wires to the contacts of said microelectronic element and second ends of said plurality of conductive wires to the conductive pads of said second substrate.
