A semiconductor package is disclosed including a plurality semiconductor
die mounted on stacked and bonded layers of substrate, for example
polyimide tape used in tape automated bonding processes. The tape may
have a plurality of repeating patterns of traces and contact pads formed
thereon. The traces each include aligned interconnect pads on the
respective top and bottom surfaces of the substrate for bonding the
traces of one pattern to the traces of another pattern after the patterns
have been singulated from the substrate, aligned and stacked.
Semiconductor die such as flash memory and a controller die are mounted
on the traces of the respective patterns on the substrate. In order for
the controller die to uniquely address a specific flash memory die in the
stack, a group of traces on each substrate supporting the memory die are
used as address pins and punched in a unique layout relative to the
layout of the traces other substrates. By providing each flash memory
semiconductor die on a substrate with a unique layout of address traces,
each memory die may be selectively addressed by the controller die.
