摘要:
A carrier structure and method for fabricating a carrier structure with through-vias each having a conductive structure with an effective coefficient of thermal expansion which is less than or closely matched to that of the substrate, and having an effective elastic modulus value which is less than or closely matches that of the substrate. The conductive structure may include concentric via fill areas having differing materials disposed concentrically therein, a core of the substrate material surrounded by an annular ring of conductive material, a core of CTE-matched non-conductive material surrounded by an annular ring of conductive material, a conductive via having an inner void with low CTE, or a full fill of a conductive composite material such as a metal-ceramic paste which has been sintered or fused.

A method for manufacturing a self-compensating resistor within an integrated circuit is disclosed. The self-compensating resistor includes a first resistor and a second resistor. The first resistor having a first resistance value is initially formed, and then the second resistor having a second resistance value is subsequently formed. The second resistor is connected in series with the first resistor. The second resistance value is less than the first resistance value, but the total resistance value of the first and second resistors lies beyond a desired target resistance range. Finally, an electric current is sent to the second resistor to change the dimension of the second resistor such that the total resistance value of the first and second resistors falls within the desired target resistance range.

In an integrated circuit packaging structure, such as in an MCM or in a SCM, a compliant thermally conductive material is applied between a heat-generating integrated circuit chip and a substrate attached thereto. Raised regions are defined on the back side of the chip aligned to areas of a higher than average power density on the front active surface of the chip such that a thinner layer of the compliant thermally conductive material is disposed between the chip and the substrate in this area after assembly thereof resulting in a reduced “hot-spot” temperature on the chip. In an exemplary embodiment, the substrate includes one of a heat sink, cooling plate, thermal spreader, heat pipe, thermal hat, package lid, or other cooling member.

In one embodiment, a sub-pad assembly of metal structures is located directly underneath a metal pad. The sub-pad assembly includes an upper level metal line structure abutting the metal pad, a lower level metal line structure located underneath the upper level metal line structure, and a set of metal vias that provide electrical connection between the lower level metal line structure located underneath the upper level metal line structure. In another embodiment, the reliability of a C4 ball is enhanced by employing a metal pad structure having a set of integrated metal vias that are segmented and distributed to facilitate uniform current density distribution within the C4 ball. The area1 density of the cross-sectional area in the plurality of metal vias is higher at the center portion of the metal pad than at the peripheral portion of the planar portion of the metal pad.
