As we know, transistors replaced electronic tubes due to their numerous advantages. One of the advantages of the tran­sistor is its small dimensions. Because of their small size, the absence of heating and other properties, transistors make it pos­sible to produce compact, small-dimensioned electronic devices which consume very little power.

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 is 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. Microelectronics is a name for 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.
