Gae4kkka: Integrated circuitc : Brief history The semiconductor industry can trace its roots back to the invention of the first semiconductor transistor by WilLiam Shockley, John, Bardeen,and Walter Brattain in 1947.Their crude deice was assembled from a small piece of germanium some gold foil, a paper clip, and several pieces of plastic. Though crudely constructed, it performed its function of using a voltage to switch an electrical current on or off quite well. This simpl device is the parent of al of the various semiconductor transistor devices produced over the years, including computer microprocessor, memory chips, and solid state power amplification circuits. The new transistor could replace bulky and troublesome vacuum tubes ( radios and televisions ), and it created new markets that were invented specifically to exploit its use. The discrete transistor was quickly incorporated in everything from telephone equipment to pocket-sized transistor radios. It is interesting to note that the size of the parts in these early discrete devices was of the order of tenths of an inch/ By the late 1950s, the discrete transistor market was worth an estimated 1 billion annually. The next major step in semiconductor history was the invention of the first monolithic integrated circuit by Jack Kilby and Robert Noyce in 1960 . Their integrated devices consisted of many solid-state transistors that were manufactured and interconnected internally on a single semiconductor substrate. The typical minimum feature size in these early products was greater than 20mm, significantly smaller than some oh there discrete transistor counterparts. The ability to interconnection also made it possible to pack a larger amount of function into areas far smaller than was possible with discrete transistors. It was the invention of the «integrated circuit» that ushered in the modern microelectronics era, and it is still adaptations of that basic product that fuel the semiconductor industry. Invented about 50 years ago, the IC has already become one of the marvels of the electronics industry, and it is being used widely in dozens of industries and consumer products. Yet, the range of uses of this electronics device is considered to be almost limitless and is expected to influence nearly every human activity. At todai level of development, it might consist of 10,000 separate electronics elements. It replaces many separate circuits, each of which, until recently formed a network of interlaced wires, resistors and capacitors shielded coils and vacuum tubes, all hand –soldered into place. 2 Определите функцию (e)s в следующих словах: Pieces, devices, semiconductors, counterparts, replaces, coils. 3 Выпишите из текста прилагательные в сравнительной и превосходной степени. 4 Выпишите из текста предложения с модальными глаголами и их эквивалентными и переведите их. 5 Определите грамматическое время и залог следующих глаголов.
