A STACKED-DIE ELECTRONICS PACKAGE WITH PLANAR AND THREE-DIMENSIONAL INDUCTOR ELEMENTS
Abstract:
An apparatus and a method for producing three-dimensional integrated circuit packages. In one embodiment, an electronics package (200) with at least two dice (207, 209) are stacked one atop another is disclosed. A top die (209) is of smaller size compared with a bottom die (207) such that after a die attach operation, wire-bond pads of the bottom die will be exposed for a subsequent wire bonding operation. The bottom die (207) contains contact pads (211) on the front side that couple with one or more passive components (213) fabricated on the back side of the top die (209) to complete the circuit. In another exemplary embodiment, a method to form one or more three-dimensional passive components in a stacked-die package is disclosed wherein partial inductor elements are fabricated on the front side of the bottom die and the back side of the top die. The top and bottom elements are coupled together completing the passive component.
