Introduction
THE ELECTRICAL/ELECTRONICS INDUSTRY
The growing sensitivity to the technologies on Wall Street is clear evi-
dence that the electrical/electronics industry is one that will have a sweep-
ing impact on future development in a wide range of areas that affect our
life style, general health, and capabilities. Even the arts, initially so deter-
mined not to utilize technological methods, are embracing some of the
new, innovative techniques that permit exploration into areas they never
thought possible. The new Windows approach puter simulation has
puter systems much friendlier to the average person, resulting in
an expanding market which further stimulates growth in the field. The
computer in the home will eventually be mon as the telephone or
television. In fact, all three are now being integrated into a single unit.
Every facet of our lives seems touched by developments that appear to
surface at an ever-increasing rate. For the layperson, the most obvious
improvement of recent years has been the reduced size of electrical/ elec-
tronics systems. Televisions are now small enough to be hand-held and
have a battery capability that allows them to be more portable. Computers
with significant memory capacity are now smaller than this textbook. The
size of radios is limited simply by our ability to read the numbers on the
face of the dial. Hearing aids are no longer visible, and pacemakers are
significantly smaller and more reliable. All the reduction in size is due
primarily to a marvelous development of the last few decades—the
integrated circuit (IC). First developed in the late 1950s, the IC has now
reached a point where cutting -micrometer lines monplace. The
integrated circuit shown in Fig. is the Intel® Pentium® 4 processor,
which has 42 million transistors in an area measuring only square
inches. Intel Corporation recently presented a technical paper describing
-micrometer (20-nanometer) transistor
