Microelectronics
Microelectronics
is a subfield of electronics which is related to the study and
manufacture of electronic components which are very small. These
devices are made from semiconductors using a process known as
photolithography. Many components of normal electronic design are
available in microelectronic equivalents: transistors, capacitors,
inductors, resistors, diodes and of course insulators and conductors
can all be found in microelectronic devices.
Digital
integrated circuits consist mostly of transistors. Analog circuits
commonly contain resistors and capacitors as well. Inductors are
used in some high frequency analog circuits; they occupy a large
chip area if used at low frequencies.
As
techniques improve, the sizes of microelectronic components continue
to decrease. At smaller scales, the effects of minor circuit
elements such as interconnections may become more important. These
are called parasitic effects, and the goal of the microelectronics
design engineer is to find ways to compensate for or to minimize
these effects.

Solid-state
electronic
devices
are part of our everyday lives. Solid- state miniature electronic
components are in many places: the beeping sound made by a cell
phone; auto dashboard alarm; the voice chip in an answering machine;
TV
remote control;
laser pointer; the inside of an MP3
player;
a quartz
watch;
the image sensor in a digital
camera and
a camcorder;
the computer monitor,
etc.
The
transistor, invented in 1947 by Bell Labs, was the first solid-
state device to come into commercial use in the 1960s. Solid-state
electronic devices have replaced vacuum tubes in just about all
electronics devices. Vacuum tubes are still used in the transmitters
of radio stations you listen to, many guitar amplifiers and some
audiophile equipment. Vacuum tubes are the opposite of “solid-state”
because tubes burnout, break, etc.
Solid-state
gets its name from the path that electrical signals take through
solid pieces of semi-conductor material. Prior to the use of solid-
state devices, such as the common transistor, electricity passed
through the various elements inside of a heated vacuum tube.
Solid-state devices, such as a transistor, use conductors to control
the flow of signals through a circuit.
Solid
state devices called diodes have replaced rectifier vacuum tubes,
used to transform AC to DC. Cool-running light-emitting diodes
(LEDs), another solid-state device used for indicators on the front
panel of your computer and monitor, have replaced the earlier
incandescent bulbs. Multiple bright LEDs are also used for the third
stoplight on many vehicles and for traffic
signals.
Electrical
engineers design computers and incorporate them into devices and
systems. They design two-way communications systems such as
telephones and fiber-optic systems, and one-way communications
systems such as radio and television, including satellite systems.
They design control systems, such as aircraft collision-avoidance
systems, and a variety of systems used in medical electronics.
Electrical engineers are involved with generation, control, and
delivery of electric power to homes, offices, and industry. Electric
power lights, heats, and cools working and living space and operates
many devices used in homes and offices. Electrical engineers analyze
and interpret computer-aided tomography data (CAT scans), seismic
data from earthquakes and well drilling, and data from space probes,
voice synthesizers, and handwriting recognition. They
14
design
systems that educate and entertain, such as computers and computer
networks, compact-disk players, and multimedia systems.
The
integration of communications equipment, control systems, computers,
and other devices and processes into reliable, easily understood,
and practical systems is a major challenge, which has given rise to
the discipline of systems engineering. Electrical engineering must
respond to numerous demands, including those for more efficient and
effective lights and motors; better communications; faster and more
reliable transfer of funds, orders, and inventory information in the
business world; and the need of medical professionals for access to
medical data and advice from all parts of the world.

Is
it that does us good or does it bring disaster?
Science
is a source of progress. It develops the world we live in. Our
century is an epoch of great discoveries in science and engineering.
It is an epoch of scientific and technological revolution
discoveries, when new ideas are being born and new discoveries,
inventions are being made at an ever increasing rate.
Today
science has become the most important factor in the development of
national economy in the whole world. Scientific progress serves the
interests of society, helps to increase the well-being of people and
develops public education.
Computer
technology plays the most important role in the progress of science.
The ability of computers to solve many mathematical problems more
effectively than man does, has given rise to new trends in
mathematics. Computer science is a new field of study and research.
In recent years scientists of the world have achieved great success
in the development of physics, chemistry, biology, and such
astonishing, interesting science as psychology. But science may be
turned both for peace and military purpose. It can take good forms
and evil forms. With the help of scientific inventions politicians
make weapons of mass destruction. But on the other hand researches
help us in our life: at home, at work, at school and make the level
of the country development higher. That’s why there are a lot of
facts telling about a great amount of well- known scientists who had
burned their works when they’ve understood the consequences of
their inventions.
To
answer the question whether science does us good or does it bring
disaster isn’t a simple task. We should take into consideration
many facts. On the one hand a lot of outstanding discoveries made
the life of the people more comfortable and pleasant. Without
scientific discoveries and
