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： In some embodiments a method of forming a gold-aluminum electrical interconnect is described. The method may include interposing a diffusion retardant layer between the gold and the aluminum (1002), the diffusion retardant layer including regions containing and regions substantially devoid of a diffusion retardant material; bringing into contact the diffusion retardant layer, the gold, and the aluminum (1004); forming alloys of gold and the diffusion retardant material in regions containing the material (1006) and forming gold-aluminum intermetallic compounds in regions substantially devoid of the material (1008); and forming a continuous electrically conducting path between the aluminum and the gold (1010). In some embodiments, a structure useful in a gold-aluminum interconnect is provided. The structure may include an aluminum alloy bond pad (530) and a diffusion retardant layer (520) in contact with the bond pad, the diffusion retardant layer including regions (522) containing and regions (524) substantially devoid of a diffusion retardant material. The structure may include a gold free air ball (714) in contact with the diffusion retardant layer.

摘要： A semiconductor package (10) uses a plurality of thermal conductors (56-64) that extend upward within an encapsulant (16) from one or more thermal bond pads (22, 24, 26) on a die (14) to disperse heat. The thermal conductors may be bond wires or conductive stud bumps and do not extend beyond a lateral edge of the die. One or more of the thermal conductors may be looped within the encapsulant and exposed at an upper surface of the encapsulant. In one form a heat spreader (68) is placed overlying the encapsulant for further heat removal. In another form the heat spreader functions as a power or ground terminal directly to points interior to the die via the thermal conductors. Active bond pads may be placed exclusively along the die's periphery or also included within the interior of the die.
