X-Ray Diffractional Investigation of the Copper-Aluminium Interface Reaction

  • Ehrenfried Zschech
  • Andreas Kaiser


For the application of the copper wire ball/wedge bonding it is necessary to analyze the wire/substrate transition regions. The investigation of the interface reaction between copper ball and aluminium bonding pads serves for the assessment of the contact reliability at the copper ball bonds from the points of view of solid state physics.
