Webcracking, allowing much more margin in bonding stress, enabling the option of Au or Cu wire bond on the same IC without pad cracking. Key words: wirebond, circuit under pad, BOAC, Au wire, Cu wire, bond pad . Introduction . Gold (Au) wire bonding often has very little process margin because the pad structure is fragile. A gold–aluminium intermetallic is an intermetallic compound of gold and aluminium that occurs at contacts between the two metals. These intermetallics have different properties from the individual metals, which can cause problems in wire bonding in microelectronics. The main compounds formed are Au5Al2 (white plague) and AuAl2 (purple plague), which both form at high temperatures. town and country planning 1997
