The solid-state computing telecommunications aerospace automotive and consumer electronics industries all rely heavily on the quality of these methods and processes. In each of these industries dramatic changes are underway. In addition to increased performance next-generation computing is increasingly being performed by portable hand-held computers. A similar trend exists in telecommunications where the user will soon be employing high-performance multifunctional portable units. In the consumer industry multimedia products capable of voice image video text and other functions are also expected to be commonplace within the next decade. The common thread in each of these trends is low-cost electronics. This multi-billion-dollar electronics industry is fundamentally dependent on the manufacture of semiconductor integrated circuits ICs . However the fabrication of ICs is extremely expensive. In fact the last couple of decades have seen semiconductor manufacturing become so capital-intensive that only a few very large companies can participate. A typical state-of-the-art high-volume manufacturing facility today costs over a billion dollars Dax 1996 . As shown in Figure 13.1 this represents a factor of over 1000 increase over the cost of a comparable facility 20 years ago. If this trend continues at its present rate facility costs will exceed the total .
