A semiconductor device and methods of forming same are disclosed having
multiple die redistribution layer. After fabrication of semiconductor die
on a wafer and prior to singulation from the wafer, adjacent
semiconductor die are paired together and a redistribution layer may be
formed across the die pair. The redistribution layer may be used to
redistribute at least a portion of the bond pads from the first die in
the pair to a second die in the pair. One die in each pair will be a
working die and the other die in each pair will be a dummy die. The
function of the integrated circuit beneath the redistribution layer on
the dummy die is at least partially sacrificed.
