3、In fact, the history of the development of microelectronic technology is not long, on the contrary, its late start. Because until 1958, the United States microelectronics experts Kilby invented the worlds first integrated circuit germanium oscillator, the only marks the beginning of human society en
4、tered the era of microelectronics. Although a late start microelectronic technology, but as electronics and information science and technology frontier disciplines, it is in the social life and play a decisive role: it with economic development are inseparable, and is closely related to peoples live
5、s, also in the national defense and security plays irreplaceable and important role. Cite an example of life, we have to use public transport BUS IC cards, go to the hospital, pharmacy medicines used medical insurance IC cards, the use of public telephone booth telephone call IC cards are Applicatio
6、n of the products of the microelectronics technology. Today, the IC card has been widely used in finance, telecommunications, transportation, insurance, medical care, food, entertainment, identification and other fields, and led us into the VISA times. For example, we normally use to the digital hom
