Claim 18:
19. The method of claim 3 further comprising:
singulating the mold device wafer with a plurality of connected mold device dies, each of which includes a corresponding device region and a portion of the first mold compound over the corresponding device region, into a plurality of individual mold device dies, wherein each of the plurality of individual mold device dies is provided from a corresponding one of the plurality of connected mold device dies;
applying a second mold compound around and over each of the plurality of individual mold device dies to provide a double mold device wafer, wherein:
the second mold compound encapsulates a top surface and side surfaces of each of the plurality of individual mold device dies, while a bottom surface of each of the plurality of individual mold device dies is exposed; and
a bottom surface of the double mold device wafer is a combination of the bottom surface of each of the plurality of individual mold device dies and a bottom surface of the second mold compound; and

forming a multilayer redistribution structure underneath the double mold device wafer, wherein:
the multilayer redistribution structure comprises a plurality of bump structures on a bottom surface of the multilayer redistribution structure and redistribution interconnections within the multilayer redistribution structure; and
each of the plurality of bump structures is electrically coupled to one active layer of a corresponding individual mold device die via the redistribution interconnections within the multilayer redistribution structure and connecting layers within the BEOL portion of the corresponding individual mold device die.
