Abstract:
1. A method of manufacturing through substrate via (TSV) die assembly, comprising: positioning a plurality of TSV die with their topsides facing down onto a curable bonding adhesive layer on a carrier, said plurality of TSV die including contactable TSVs that include or are coupled to bondable bottomside features protruding from a bottomside of at least two TSV dies; curing said curable bonding adhesive layer after said positioning; bonding a plurality of second IC (intergrated circuit) die each having a plurality of second bonding features onto said plurality of TSV die to form a plurality of stacked die assemblies on said carrier; debonding after said bonding to separate said carrier from said plurality of stacked die assemblies; singulating said plurality of stacked die assemblies to form a plurality of singulated stacked die assemblies; attaching said plurality of said singulated stacked die assemblies to a package substrate; forming a mold layer on said package substrate lateral to said plurality of said singulated stacked die assemblies; forming through mold vias including electrically conductive features lateral to said plurality of said singulated stacked die assemblies; attaching solder balls on a side of said package substrate opposite to said plurality of said singulated stacked die assemblies; and singulating said package substrate.
