Patent ID: 7952205

Claim:
A method for conductively joining a plurality of superimposed layers of semiconductor components to a mold, said method comprising: forming a plurality of solder columns through injection molded soldering; having said formed solder columns electrically connecting each said semiconductor component of a respective superimposed layer of said semiconductor components with electrical components and connections on said mold having cavities; filling at least some of said cavities with said solder to form additional solder columns; transferring said mold with said additional solder columns to a carrier for said semiconductor component layers; causing said additional solder columns to be adhered to said semiconductor components to produce the conductive connections therewith; forming cutouts in said mold for receiving additional semiconductor components for attachment to said carrier by at least some of said cavities being devoid of solder; locating a filler head for extruding solder above said mold for filling solder into said cavities to form said solder columns; filling said cutouts with solder extruded from said solder filler head; and applying a shaped wettable material to said cutouts to remove solder therefrom and facilitate the positioning therein of semiconductor chips or electronic components.
