Patent ID: 7820483

Claim:
A method for conductively joining a plurality of superimposed layers of semiconductor components to a substrate or mold, said method comprising: forming a plurality of solder columns through injection molded soldering and connecting said plurality of solder columns to each of a respective superimposed layer of semiconductor components including a carrier being positioned at the bottom of said respective superimposed layers of said semiconductor components, said carrier being connected to a component by said solder columns; having said formed solder columns electrically connecting each said semiconductor component of said respective superimposed layers of said semiconductor components with electrical components and connections on said mold; and said mold having cavities; filling at least some of said cavities in said mold with said solder to form said solder columns using said injection molded soldering; transferring said respective superimposed layers of said semiconductor components with said solder columns to said mold causing said solder columns to be adhered to said semiconductor components and causing at least some of said solder columns in said mold to connect with said carrier to produce the conductive connections between said semiconductor components and said mold, and wherein at least one of said cavities in said mold is devoid of solder to form a cutout in said mold for receiving said component.
