By Shankara K. Prasad

"Advanced Wirebond Interconnection know-how addresses cord bonding from either production and reliability views. It analyzes and explores many of the elements that one must examine: layout, fabrics, processing, apparatus, caliber trying out and reliability engineering, and final yet now not least, operator education. This ebook is meant to be a finished resource of data and information that allows either a newcomer to the sector and a veteran who wishes quick info to decide on a strategy challenge. The e-book explains not just how you can do issues resembling designating a bond pad or a lead finger, easy methods to decide upon a correct bond twine, the right way to layout a capillary and the way to optimize a bonding technique at the manufacturing unit flooring, however the publication additionally explains why to do it that approach. A CD-ROM is integrated, which includes second and 3D animations of many options which are mentioned during this booklet. The animations with voice-overs aid the reader grab the information quicker with visible event, which ends up in greater retention.

In addition to consistent productivity, today’s Ultra Fine Pitch wire bonding applications require that the bond-wire geometry has very low loop, very short loop, and use very thin wire. The bonding wire must meet these critical requirements of fine pitch applications. Many high power IC applications also demand high current carrying capability of the bonding wire and high fatigue resistance. Long term reliability requirements of the IC device demand that the wire must ensure high mechanical strength and corrosion resistance in harsh environments.

4 Thermocompression Bonding In thermocompression bonding of Au wire, we use only high temperature and bonding force to create the bond between the Au wire and the bondpad. No ultrasonic energy is used during bonding. This has certain advantages and is used in special applications such as bonding of GaAs devices. 5 Comparison of the Three Bonding Technologies In the semiconductor industry, the most widely used wire bonding technology is the thermosonic bonding, followed by ultrasonic bonding and thermocompression bonding technologies.

However, high current requirements of power devices need the current-carrying capability of 125 to 200 micron wires. 3 High Current Carrying Capability Thinner wires have smaller current carrying capacity than thicker wires, resulting in higher probability for wire fusing under high power conditions. The current carrying capacity is generally measured as the maximum current the wire can carry before it fuses or burns off. 8. As the Au wire diameter increases, the current carrying capability of the wire also increases.
