This critical volume provides an in-depth presentation of copper wire bonding technologies, processes and equipment, along with the economic benefits and risks. Due to the increasing cost of materials used to make electronic components, the electronics industry has been rapidly moving from high cost gold to significantly lower cost copper as a wire bonding material. However, copper wire bonding has several process and reliability concerns due to its material properties. Copper Wire Bonding book lays out the challenges involved in replacing gold with copper as a wire bond material, and includes the bonding process changes—bond force, electric flame off, current and ultrasonic energy optimization, and bonding tools and equipment changes for first and second bond formation. In addition, the bond–pad metallurgies and the use of bare and palladium-coated copper wires on aluminum are presented, and gold, nickel and palladium surface finishes are discussed. The book also discusses best practices and recommendations on the bond process, bond–pad metallurgies, and appropriate reliability tests for copper wire-bonded electronic components. In summary, this book: Introduces copper wire bonding technologies Presents copper wire bonding processes Discusses copper wire bonding metallurgies Covers recent advancements in copper wire bonding including the bonding process, equipment changes, bond–pad materials and surface finishes Covers the reliability tests and concerns Covers the current implementation of copper wire bonding in the electronics industry Features 120 figures and tables Copper Wire Bonding is an essential reference for industry professionals seeking detailed information on all facets of copper wire bonding technology.

Electronics has become the largest industry, surpassing agriculture, auto, and heavy metal industries. It has become the industry of choice for a country to prosper, already having given rise to the phenomenal prosperity of Japan, Korea, Singapore, Hong Kong, and Ireland among others. At the current growth rate, total worldwide semiconductor sales will reach $300B by the year 2000. The key electronic technologies responsible for the growth of the industry include semiconductors, the packaging of semiconductors for systems use in auto, telecom, computer, consumer, aerospace, and medical industries, displays, magnetic, and optical storage as well as software and system technologies. There has been a paradigm shift, however, in these technologies, from mainframe and supercomputer applications at any cost, to consumer applications at approximately one-tenth the cost and size. Personal computers are a good example, going from $500IMIP when products were first introduced in 1981, to a projected $IIMIP within 10 years. Thin, light portable, user friendly and very low-cost are, therefore, the attributes of tomorrow's computing and communications systems. Electronic packaging is defined as interconnection, powering, cool ing, and protecting semiconductor chips for reliable systems. It is a key enabling technology achieving the requirements for reducing the size and cost at the system and product level.

Microelectronics packaging and interconnection have experienced exciting growth stimulated by the recognition that systems, not just silicon, provide the solution to evolving applications. In order to have a high density/ performance/yield/quality/reliability, low cost, and light weight system, a more precise understanding of the system behavior is required. Mechanical and thermal phenomena are among the least understood and most complex of the many phenomena encountered in microelectronics packaging systems and are found on the critical path of neatly every design and process in the electronics industry. The last decade has witnessed an explosive growth in the research and development efforts devoted to determining the mechanical and thermal behaviors of microelectronics packaging. With the advance of very large scale integration technologies, thousands to tens of thousands of devices can be fabricated on a silicon chip. At the same time, demands to further reduce packaging signal delay and increase packaging density between communicat ing circuits have led to the use of very high power dissipation single-chip modules and multi-chip modules. The result of these developments has been a rapid growth in module level heat flux within the personal, workstation, midrange, mainframe, and super computers. Thus, thermal (temperature, stress, and strain) management is vital for microelectronics packaging designs and analyses. How to determine the temperature distribution in the elec tronics components and systems is outside the scope of this book, which focuses on the determination of stress and strain distributions in the electronics packaging.

All packaging engineers and technologists who want to ensure thatthey give their customers the highest quality, most cost-effectiveproducts should know that the paradigm has shifted. It has shiftedaway from the MIL-STDs and other government standards and testprocedures that don't cost-effectively address potential failuremechanisms or the manufacturing processes of the product. It hasshifted decisively towards tackling the root causes of failure andthe appropriate implementation of cost-effective process controls,qualityscreens, and tests. This book's groundbreaking, science-based approach to developingqualification and quality assurance programs helps engineers reacha new level of reliability in today's high-performancemicroelectronics. It does this with powerful... * Techniques for identifying and modeling failure mechanismsearlier in the design cycle, breaking the need to rely on fielddata * Physics-of-failure product reliability assessment methods thatcan be proactively implemented throughout the design andmanufacture of the product * Process controls that decrease variabilities in the end productand reduce end-of-line screening and testing A wide range of microelectronic package and interconnectconfigurations for both single-and multi-chip modules is examined,including chip and wire-bonds, tape-automated (TAB), flip-TAB,flip-chip bonds, high-density interconnects, chip-on-board designs(COB), MCM, 3-D stack, and many more. The remaining packageelements, such as die attachment, case and lid, leads, and lid andlead seals are also discussed in detail. The product of a distinguished team of authors and editors, thisbook's guidelines for avoiding potential high-risk manufacturingand qualification problems, as well as for implementing ongoingquality assurance, are sure to prove invaluable to both studentsand practicing professionals. For the professional engineer involved in the design andmanufacture of products containing electronic components, here is acomprehensive handbook to the theory and methods surrounding theassembly of microelectronic and electronic components. The bookfocuses on computers and consumer electronic products with internalsubsystems that reflect mechanical design constraints, costlimitations, and aesthetic and ergonomic concerns.
