Patent ID: 7479407

Claim:
A method for forming a stacked die system, comprising: providing a package substrate; placing a first die over the package substrate, the first die having a first surface with active circuitry; applying a first epoxy resin over the first die; placing a conductive shield over the first die and the first epoxy resin after the step of applying the first epoxy resin; applying a second epoxy resin over the conductive shield after the step of placing the conductive shield; placing a second die over the conductive shield, the second die having a first surface with active circuitry, wherein the conductive shield is between the first surface of the first die and the first surface of the second die; forming electrical connections between the active circuitry of the first die and the package substrate; forming electrical connections between the active circuitry of the second die and the package substrate; obtaining a wafer having an aluminum coating; and singulating the wafer to form the conductive shield, wherein the step of obtaining is further characterized by the wafer comprising silicon.
