WitrynaAl metallization. If bonding parameters are optimised, most of the interfacial area, as much as 70-80%, should consist of IMC. The minimum amount of IMC needed for the … WitrynaAbstract. In order to clarify the reliability of Au wire bonds to Al pads, void formation and diffusion behavior were investigated using bonds annealed at various temperatures (423-573 K). We investigated the effects of the annealing environments, Al pad thickness, and bonding conditions on void formation. Voids became larger only when Au-Al ...
