Introduction of Electronic Technology
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 world's first integrated circuit "germanium oscillator," the only marks the beginning of human society entered 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 people's lives, 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 Application of the products of the microelectronics technology. Today, the IC card has been widely used in finance, munications, 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 home appliances, such as MP3, digital cameras, mobile phones, television sets and so on, they are the crux of the information processing part, is what we call "chips", but also is the application of mic
