Patent ID: 7454834

Claim:
A method of making a plurality of microelectronic packages comprising the steps of: providing a plurality of first microelectronic elements having electrically conductive parts and including first and second surfaces; providing a plurality of compliant elements over said first surfaces of said first microelectronic elements, each said compliant element including a releasable adhesive at a surface remote from said first microelectronic element; providing a plurality of second microelectronic elements having electrically conductive parts abutting said second microelectronic elements against said releasable adhesive so that said second microelectronic elements and said first microelectronic elements are releasably assembled such that they adhere to each other but may be released from each other without heat, thereby forming a plurality of releasably assembled packages; connecting said electrically conductive parts of said first and second microelectronic elements; testing said plurality of releasably assembled packages so as to identify first and second assembled packages, wherein said testing step follows said step of connecting said electrically conductive parts; disassembling said first and second microelectronic elements of said first assembled packages, by breaking the connection between said electrically conductive parts of said first and second microelectronic elements; providing a curable liquid between said first and second microelectronic elements of said second assembled packages; and curing said curable liquid so that said first and second microelectronic elements of said second assembled packages are permanently assembled to one another.
