Book Description
The feasibility of using aluminum ribbon wire for ultrasonic bonding of semiconductor microelectronic interconnections was studied, and several advantages over the use of round wire of equivalent cross-sectional area were found. Ribbon wire bonds exhibited little deformation or heel damage, and a greater percentage of bonds of a certain quality (as judged by pull strength and appearance) could be made over much greater ranges of the bonding machine parameters, time and tool tip displacement, using ribbon wire than was possible with round wire. The ease of positioning ribbon wire was indicated by making multiple ribbon wire bonds side-by-side on a 5-mil square pad, or by stacking up to four bonds one on top of another. However, bonding with harder than normal wire, previously thought to offer certain advantages with respect to higher bond tensile strength, yielded inconsistent results.

Book Description
Intended for wire-bonding and flip-chip packaging professionals and for scientists and engineers working in the field of mechanical microsensors, this practical monograph introduces novel measurement technologies that allow for in situ and real-time examination of physical processes during the packaging process or during subsequent reliability tests. The measurement system presented here makes possible measurements at formerly inaccessible packaging interconnects. For the first time it becomes possible to describe the wire-bonding process window in terms of the physical forces at the contact zone instead of the applied machine settings. This is significant for a deeper understanding and future development of these packaging processes. Applications of the sensor in the field of wire bonding and flip-chip characterization are also illustrated. The reader will gain much insight into the important field of interconnection technology in semiconductor packaging.

Book Description
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.

Book Description
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.
