Plasma Before Wire Bonding • Plasma Treatment to: • Remove Organic, Metal, Halogen, and Oxide contamination from bond pads (both die & substrate) • Benefits • Increase wire bond (pull, shear) strength • Increase wire bond yields (Cpk) • Increase wire bond reliability • Reduce scrap/re-work • Reduce costs Wire Bond Attach Rate ~100% (both Ball & Wedge) thanks to Plasma Treatment Courtesy ASM, C.
