Abstract:
1. A microelectronic die assembly comprising: a microelectronic die; a thermally conductive element attached to the backside of the die, the thermally conductive element having lateral dimensions smaller than lateral dimensions of the die by up to about 10% smaller, substantially equal to, or larger than lateral dimensions of the die by up to a maximum amount of about 10%, wherein the lateral dimensions of the thermally conductive element in relation to the lateral dimensions of the die is adapted to allow a mounting of the die assembly to a package substrate and the lateral dimensions of the thermally conductive element in relation to the lateral dimensions of the die is adapted to allow a wafer level attachment of the thermally conductive element to the backside of the die; and a thermal interface material attaching the thermally conductive element to the backside of the die to yield the die assembly.
