Text 1. DEVELOPMENT OF ELECTRONICS

Electronics is a field of engineering and applied physics deal­ing with the design and application of electronic circuits. The operation of circuits depends on the flow of electrons for gen­eration, transmission, reception and storage of information.

Today it is difficult to imagine our life without electronics. It surrounds us everywhere. Electronic devices are widely used in scientific research and industrial designing, they control the work of plants and power stations, calculate the trajectories of space-ships and help the people discover new phenomena of nature. Automatization of production processes and studies on living organisms became possible due to electronics.

The invention of vacuum tubes at the beginning of the 20^th century was, the starting point of the rapid growth of modern electronics. Vacuum tubes assisted in manipulation of signals. The development of a large variety of tubes designed for spe­cialized functions made possible the progress in radio commu­nication technology before the World Vfar II and in the creation of early computers during and shortly after the war.

The transistor invented by American scientists WShockly, J.Bardeen and WBrattain in 1948 completely replaced the vac-

uum tube. The transistor, a small piece of a semiconductor withthree electrodes, had great advantages over the best vacuum tubes. It provided the same functions as the vacuum tube but at reduced weight, cost, power consumption, and with high reli­ability. With the invention of the transistor all essential circuit functions could be carried out inside solid bodies. The aim of creating electronic circuits with entirely solid-state components had finally been realized. Early transistors could respond at a rate of a few million times a second. This was fast enough to serve in radio circuits, but far below the speed needed for high­speed computers or for microwave communication systems.

The progress in semiconductor technology led to the devel­opment of the integrated circuit (1С), which was discovered due to the efforts of John Kilby in 1958. There appeared a new field of science — integrated electronics. The essence of it is batch processing. Instead of making, testing and assembling descrete components on a chip one at a time, large groupings of these components together with their interconnections were made all at a time. 1С greatly reduced the size of devices, lowered man­ufacturing costs and at the same time they provided high speed and increased reliability.

Text 2. MICROELECTRONICS AND MICROMINIATURIZATION

The intensive effort of electronics to increase the reliability and performance of its products while reducing their size and cost led to the results that hardly anyone could predict. The evolution of electronic technology js sometimes called a revo­lution: a quantitative change in technology gave rise to qualita­tive change in human capabilities. There appeared a new branch of science — microelectronics.

Microelectronics embraces electronics connected with the realization of electronic circuits, systems and subsystems from very small electronic devices. NJicxaelfifitrQnics jaLa-name ft* extremely small electronic components and circuit assemblies, made by film or semiconductor techniques. A microelectronic technology reduced transistors and other circuit elements to dimensions almost invisible to unaided eye. The point of this extraordinary miniaturization is to make circuits long-lasting, low in cost, and capable of performing electronic functions at extremely high speed. It is_ known that the speed of response depends on the size of transistor: the smaller the transistor, the faster it is. The smaller the computer, the faster it can work.

One more advantage of microelectronics is that smaller de­vices consume less power. In space satellites and spaceships this is a very important factor.

Another benefit resulting from microelectronics is the reduc­tion of distances between circuit components. Packing density increased with the appearance of small-scale integrated circuit, medium-scale 1С, large-scale 1С and very-large-scale 1С. The change in scale was pieasured_by the number of transistors on a chip. There appeared a new type of integrated circuits, micro­wave integrated circuit. The evolution of microwave 1С began with the development of planar transmission lines.Then new 1С components in a fineline transmission line appeared. Other more exotic techniques, such as dielectric waveguide integrat­ed circuits emerged.

Microelectronic technique is continuing to displace othermodes. Circuit patterns are being formed with radiation having wavelength shorter than those of light.

Electronics has extended man's intellectual power. Micro­electronics extends that power still further.
