| 摘要 |
A method of making a stacked microelectronic assembly includes providing a flexible substrate having first and second ends, the flexible substrate having a plurality of attachment sites located between the first and second ends thereof including a first one of the attachment sites located adjacent the first end of the flexible substrate, the flexible substrate including conductive terminals accessible at a surface of the flexible substrate and wiring connected to the terminals, providing a compliant layer over the first attachment site, assembling a plurality of microelectronic elements over the attachment sites, wherein a first one of the microelectronic elements engages the compliant layer and is movable relative to the flexible substrate, electrically interconnecting the microelectronic elements and the wiring, folding the flexible substrate and stacking at least some of the microelectronic elements in generally vertical alignment with one another so that the first one of the microelectronic elements engaging the compliant layer is disposed at a bottom of the stacked assembly, and maintaining the stacked microelectronic elements in the substantially vertical alignment, wherein the conductive terminals are exposed at the bottom end of the stacked assembly.
