Abstract: The present invention is directed toward systems, packages, and methods for providing improved thermal performance in such packages and systems. Embodiments of the invention include a semiconductor integrated circuit (IC) package having a substrate with a heat spreader mounted on the substrate. An IC die is mounted to the heat spreader such that the heat spreader lies in between the die and the substrate. The invention is also directed to a heat spreader plate useable in a semiconductor package. The heat spreader plate comprises a plate comprised of thermally conductive material suitable for attachment to a packaging substrate wherein the plate includes openings for exposing electrical bonding surfaces of a packaging substrate when the heater spreader plate is mounted on the packaging substrate. Such openings enable wirebonding between the exposed electrical bonding surfaces of the substrate and an integrated circuit die to complete construction of a package including the heatspreader.

The first electrically nonconductive material has a first degree of fragility and a first dielectric constant. A second electrically nonconductive material is disposed in a pattern within the first electrically nonconductive material and between the electrically conductive layers, and provides structural support for the first electrically nonconductive material between the electrically conductive layers. The second electrically nonconductive material has a second degree of fragility that is less than the first degree of fragility and a second dielectric constant that is greater than the first dielectric constant.

Abstract: An integrated circuit having a top passivation layer and bonding pads, where the improvement is a metal layer overlying all of the integrated circuit. The metal layer overlies the top passivation layer and is not in electrical contact with any of the bonding pads. In this manner, there is a structure that is added to the integrated circuit which has a relatively high thermal conductivity, and which also has a relatively high structural strength. With these two added properties, the occurrence of stress cracks, such as those induced by plastic molded packages, is reduced, and hot spots tend to be dissipated. Thus, the overlying metal layer tends to improve the reliability of the integrated circuit.

Abstract: A wire bond assembly includes a multitude of bond pads arranged in an array on the surface of a die among the active circuitry and wires for electrically connecting the bond pads on the die to the substrate. As the bond pads on the die are not limited to the perimeter of the die a greater density of bond pads can be achieved and therefore the overall dimensions of the die can be reduced.

Abstract: An integrated circuit package includes a connector board and plural levels of individual conductors and conductive vias disposed through the connector board to form electrical connections between external connection pads on an undersurface of the connector board and finger connections on the upper surface of the connector board. An integrated circuit die is mounted in a central region of the connector board within confines of the individual conductors that are arranged about the die, and wire bond connections are formed between selected ones of the finger connections, the individual conductors, and the connection pads on the integrated circuit die to provide distributed connections for ground and power at one or more operating voltage levels on the individual conductors.

Abstract: An integrated circuit topography is provided which includes at least two rows of bonding pads. Each row of bonding pads is attributed a row of probe pads. One row of probe pads is contained within the scribe area and suffices as a sacrificial row of probe pads. The other row of probe pads is placed toward the interior of the integrated circuit. The rows of bonding pads and probe pads extend along parallel axis around all four sides of the integrated circuit. Every other bonding pad within one row of bonding pads is connected to every other probe pad within the scribe area, and every other bonding pad within the other rows of bonding pads is connected to every probe pad within the row of probe pads interior to the integrated circuit. This allows a fan-out configuration of the bonding pads to probe pads for purposes of probing electrical performance of the integrated circuit without having to use selected ones of the bonding pads.
