Abstract:
1. A method comprising: (a) providing a fan-out wafer having a plurality of integrated circuit (IC) dies fixed in a medium, the fan-out wafer having a redistribution layer over the IC dies, the redistribution layer having conductors connecting first pads of the IC dies to second pads at an exposed surface of the fan-out wafer; (b) mounting a plurality of die units over respective IC dies of the fan out wafer, each die unit having a package substrate with contacts and a bottom die, (c) connecting the contacts of each package substrate to ones of the second pads corresponding to at least one respective IC die; and (d) after step (c), cutting the fan-out wafer, so as to separate the at least one IC die connected to each package substrate from the IC dies connected to each other package substrate.
