摘要: An integrated circuit die (10) has a copper contact (16, 18), which, upon exposure to the ambient air, forms a native copper oxide. An organic material is applied to the copper contact which reacts with the native copper oxide to form an organic coating (12, 14) on the copper contact in order to prevent further copper oxidation. In this manner, further processing at higher temperatures, such as those greater than 100 degrees Celsius, is not inhibited by excessive copper oxidation. For example, due to the organic coating, the high temperature of the wire bond process does not result in excessive oxidation which would prevent reliable wire bonding. Thus, the formation of the organic coating allows for a reliable and thermal resistance wire bond (32, 34). Alternatively, the organic coating can be formed over exposed copper at any time during the formation of the integrated circuit die to prevent or limit the formation of copper oxidation.

摘要: An integrated circuit is packaged using a package substrate that has a bottom side with a regular array of connection points and a top side with the integrated circuit on it. Vias in the package substrate provide electrical connection between the top and bottom sides. The vias have a via capture pad to which a wire may be wire bonded so that the wires from the IC to the substrate top side directly contact the vias at their capture pads without the need for traces from a top side bond pad to a via. The via capture pad is shaped to include at least one sharp edge to improve the ability of a wirebonder with pattern recognition software to locate the capture pad and place the wire.

摘要: An improved method of bonding an insulated wire (14) that has one end connected to a first bond pad (16) to a second bond pad (18) includes moving a tip of a capillary (20) holding the bond wire (14) over the surface of the second bond pad (18) such that the bond wire (14) is rubbed between the capillary tip (20) and the second bond pad (18), which tears the bond wire insulation so that at least a portion of a metal core of the wire (14) contacts the second bond pad (18). The wire (14) is then bonded to the second pad (18) using thermocompression bonding. The tip of the capillary (20) is roughened to enhance the tearing of the bond wire insulation.

摘要: A method of making an integrated circuit package, such as a ball grid array, includes providing a flexible tape that has first and second sets of bond pads on respective first and second surfaces thereof. A carrier is attached to the first surface of the flexible tape. Then conductive pillars are formed on the second set of bond pads and an intermediate layer of polymeric compound is deposited on the second surface of the flexible tape. After the compound has cured, a surface of the intermediate layer is ground to expose ends of the conductive pillars to form a sub-assembly comprising the flexible tape and the intermediate layer. Then the carrier is removed from the sub-assembly, thereby creating an interposer. The interposer is attached to a substrate and at least one die is attached to the interposer.

摘要: A packaged semiconductor device has an integrated circuit (IC) die and first and second volumes of molding compound. The first volume of molding compound is disposed on a first portion of a first side of the IC die and comprises a first molding compound. The second volume of molding compound is disposed on a second side of the IC die, different from the first side, and comprises a second molding compound, different from the first molding compound. By including different molding compounds, the properties of the packaged semiconductor device can be varied across the device.
