15、electronics and nanoelectronicsMicroelectronic technology and microelectronic technology are the direct foundation of modern electronic information technology. Three scientists from the Baer Institute in America won the Nobel prize for physics in 1956 for the development of the first crystalline tri
16、ode. Transistors become the basis of the development of integrated circuit technology, and modern microelectronic technology is a high and new electronic technology based on various semiconductor devices with integrated circuit as the core. The production of integrated circuit started in 1959. It is
17、 characterized by its small size, light weight, high reliability and fast operation.Sign of microelectronic technology progress in three aspects: one is to reduce the chip size of the device structure, namely reduces processing line width; two is to increase the number included in the chip component
18、s, namely the integration scale; the three is the development of the design and application of. Large scale integrated circuit (LSI) means that more than one thousand components can be fabricated on each single silicon wafer. The integration degree is above ten thousand to one hundred thousand, and
19、the components are very large scale integrated circuits. Internationally, in 80s, large-scale and super large scale integrated circuit lithography standards, line width of 0.7, 0.8 microns, integration of 108. The standard line width in 90s was 0.3, 0.5 microns, and the integration level was 109. In
20、tegrated circuits have dedicated circuits (such as clocks, cameras, washing machines, etc.) and general circuits. The most typical circuits in general circuits are memory and processor, which are widely used. The upgrading of the computer depends on the integration scale of the two integrated circui
21、ts. Memory is a device with information storage capability. With the development of integrated circuit, semiconductor memory has been widely used to replace the magnetic memory used in the past. It has become an information storage device in the process of computer digital operation and information
22、processing. Memory size (or capacity) is often in bytes, bytes in uppercase letters B, memory chip integration has been millions of bits (MB) as a unit. At present, the lab has made 8MB dynamic memory chip. A Chinese character occupies 2 bytes, that is to say, 4 million characters can be placed on a
23、 silicon chip of fingernail size. The integration of dynamic memory has grown at a rate of quadrupling every 3 years. The central processing unit (CPU) is another important aspect of integrated circuit technology. Its main function is to perform instructions, perform calculations, or process data. T
24、he CPU of modern computers usually consists of hundreds of thousands to millions of transistors. In the 1980s, 70, with the development of microelectronics, a complete CFU could be made on a fingernail sized silicon chip. The most important indicator of CPU performance is speed, which is how many in
25、structions it can execute per second. At the beginning of the 60s, the fastest CPU could execute 1 million instructions per second (often abbreviated as MIPS). In 1991, the speed of high-end microprocessors had reached 5000, in case 80 million times. Now continue to improve technology RISC CPU speed
26、 (i.e. complex instruction reduction, reduction) and parallel computing technology (and the concurrent execution of several instructions) is under development. In this field, Intel, the Silicon Valley company, has been in the lead. In addition, the combination of Optics and electronics has become a
27、photoelectric technology, known as the tip of the tip, and has found a new way for the further development of microelectronic technology. Time magazine predicts: “twenty-first Century will be the photoelectron era.“.“ It mainly owns laser technology, infrared technology, optical fiber communication
28、technology and so on. edit this paragraph, edit this paragraph edit this paragraphMicroelectronic technology and large scale integrated circuitsMiniaturized integrated systems, microelectronics, have brought prosperity to mankind for half a century. At present, 8 wafer and 0.35um process have been w
29、idely used in IC production line internationally. The level of large-scale production of integrated circuits in our country is developing very fast. 1995 has reached the level of 61.2um, IC production is expected to reach an annual output of 1 billion blocks in 2000. In April 1995, the Chinese Acade
30、my of Sciences Microelectronics Center has developed a CMOS 0.8um process, in the area of 5 * 5.7mm 26000 transistor, the output pin number 72 integrated, made the general fuzzy control integrated block. High density electronic assembly technology, integrated circuit IC actually completed the chip l

Well then,Can the high integrated SI/VLSI/ULSI (mass / magpie peptone / large scale ultra large scale integrated circuit) and ASIC/ FPGA/EPLD (special IC / FPGA / electrically erasable programmable logic device) assembled together to achie
32、ve the function of IC integration? These are SMT (surface mount technology), HWSI (mixed wafer scale integration) and 3D (3D assembly technology). These technologies, to promote electronic equipment and products to continue to develop in the light thin short, small chip components and automatic inst
33、allation of equipment can handle the size of the component is on the verge of the limit today, plays a key role. Into 90s, the representative technology is the turn of MCM, called multi chip assembly era, by 2000, the beginning of the next century, will be the WSI/HWSI/3D era! WSI is the integration
34、 of complex electronic circuits on a large wafer. IC chip, MCM and WSI for three-dimensional stacked 3D assembly, breaking the two-dimensional limit, so that the assembly density to a higher level. In the last few decades, electronic computers have undergone several generations of change, which are
35、marked by scale changes in basic electronic units that store or process information from generation to generation. Since 80s, scientists have begun to explore electronics with characteristic sizes of nanometers. Nanoelectronics mainly studies single atom or single molecule manipulation techniques us
36、ing scanning tunneling microscopy (STM). These techniques are possible in the process of nanometer, nanometer scale has been formed, information storage, storage status has been maintained for more than a month, hoping to use this technique to make the memory of 16GB. Dr Fawkes of Germany made atomi
37、c switches, which reached 1 million times the storage capacity of todays chips and won the Maurice prize. Quantum mechanics tells us that both electrons and light have Li Zibos properties, and todays microelectronics and optoelectronic devices will shrink to. 0.1 linewidth, the nature of electronic
38、fluctuations can no longer be ignored, and the theory of semiconductors, which considers electrons as a purely particle, has been shaken. At this point, the fluctuations and the quantum functions possessed by electrons are the tasks of nanoelectronics. Nanoelectronics has more attractions. Scientist
39、s have predicted that nanoelectronics will lead to a revolution in electronic technology! Computer science and Technology (1) supercomputers and microcomputers, at present, the overall direction of the development of electronic computer hardware is still to improve speed, expand capacity, increase f
40、unctionality, improve the interface and reduce volume. Small computer system tends to diversification, and promote the development of PC personal computers and workstations, is replacing the large and medium-sized machine. As for supercomputers, all countries in the world pay great attention to it.
41、In 1991, the vice president of the United States, Gore, introduced the high performance computer and communications program (HPCC plan) to accelerate research in the computer and information networks between 19921 996 and to strengthen the US leadership. They develop the giant machine to solve the f

Present hundredMill
43、ion of secondary supercomputers have been fully flowering in the United States and Japan, and billions of secondary supercomputers have been introduced. In 1992, the United States NCUBE company has announced the development performance index all reached 3T (Trillion) is teraflops, terabytes of stora
44、ge, CPU and memory are per trillion bytes of bandwidth of a new generation of supercomputers. (two) Internet global computer network in order to realize the sharing of information resources, the Internet continues to expand, the most representative of the net, is joined the computer online operation
45、 of more than 140 countries and regions, the number of Internet users reached about 3800000, more than about 35000000 of the net. More than 4800 organizations have registered the Internet network address,There are more than 160 countries and regions through which users communicate with E-mail. By th
46、e end of the century, 1 million networks, 100 million computers and 1 billion users will be expected to use it. The goal of modern communication is “global network“! It is based on digital technology, computer technology, microelectronics and Optoelectronics technology. The general trend is that dig

The three heat flows in todays communication industry are optical fiber communication, satellite communication and mobile communication
48、. Modern communication technology (1) optical fiber communication technology, the light wave is electromagnetic wave, the wavelength of micron level and frequency in the level of 1014Hz, 1031 is more than 04 times higher than the microwave, so have higher communication capacity and thousands of time
49、s. How does the existing fiber optic window accommodate 20000GHz bandwidth signals and how to exploit its potential? One is to increase the bit rate of the signal; one is to use coherent optical communication; the other is to use erbium doped fiber amplifier; one is to adopt the optical frequency division multiplexing technology, and the other is to adopt optical soliton communication. What is an optical soliton? Optical pulses can form solitons when they are compensated by the nonlinearity of the fiber and the dispersion of the fiber. Optical soliton pulses can be transmitted
