Abstract: A stacked die system (10) has a first die (16) having a first surface with active circuitry, a second die (18) having a first surface with active circuitry, and a conductive shield (28) interposed between the first surface of the first die and the first surface of the second die. In one embodiment, the distance between the first surfaces of the first and second die is less than one millimeter. The stacked die system may also include a package substrate (12) where the active circuitry of the first and second die are electrically connected to the package substrate. The electrical connections may be formed using wire bonds (56, 58, 60, 62). Alternatively, the first die may be connected to the package substrate in a flip chip configuration. In one embodiment, the active circuitry of the first die generates RF signals where the shield helps protect the RF signals from interference caused by the active circuitry of the second die.

Abstract: A semiconductor package assembly 10 has an intervening package (12) that may be connected to a first package (14) from a first substrate (20) on a first side of the package (12) and to a second package (13) from a second substrate (53) on a second, opposing side of the package (12). Electrical contact to a semiconductor die (32) is made from the first side by wire bonding to wire bond posts (26) and by balls (46, 48) from the second side. Electrical contact from one side of the intervening package (12) to the other may be made by bypassing the die. Electrical contact on either side of the intervening package may be made both within and outside the footprint of the semiconductor die (32).

Abstract: An interconnect structure, such as a flip-chip structure, including a base pad and a stud formed on the base pad and extending from the base pad is disclosed. The stud and base pad are formed to be continuous and of substantially the same electrically conductive base material. Typically, a solder structure is formed on the stud wherein the solder structure is exposed for subsequent reflow attachment to another structure. The present invention relates to packaging integrated circuits, more particularly to the structure and processing of a stud and bump without the standard under bump metallurgy.
