To give you today is the micro-electronics or the introduction of the integrated circuit design, we will, as well as micro-electronics and micro-electronics history of the development of a simple set of
2, we look at that picture, the students probably have cell phones, most of the students also have a very powerful mobile phone functions, in addition to phone calls and send text messages, you can listen to music, radio, play games, Internet, etc. But let us take a look at 10 years ago, we use the phone, not only in size, and features a single, only a phone call, the price is quite expensive (more than 10,000)
3, changing not only our cell phones, the students have used computers, mp3 like electronics, 10 years ago, the memory capacity will be dozens of megabytes, but the price thousands are now easily capacity of more than 100 hard disk G, but as long as a few hundred pieces, in fact all kinds of electrical appliances are getting smaller and smaller, more powerful features, prices fall lower and lower.
4, you may ask, why would they change? There are many reasons, but the most fundamental reason is that micro-electronics technology, micro-electronics technology at the core - led to the development of integrated circuit technology, these revolutionary changes.
5, micro-electronics What is it? We look at the definition of micro-electronics is --
6, simple, micro-electronics to do is micro-circuits, as we reflected in the picture, e-learning is the tall man, and micro-electronics is on the right side of the short men, which is almost the same as , Just do less and less.
7, micro-electronics is a core IC design, IC design is the so-called active components is (diodes, transistors, etc.) and passive components (resistors, capacitors, etc.) and their connection together in the production of semiconductor substrates On the formation of an independent entity. Will be able to achieve the overall number of circuit functions.
8, Next, let us look at the history of the development of micro-electronics, see pictures, referred to the micro-electronics, we have to mention the development of the transistor, the transistor can be said to constitute the most basic unit of integrated circuits, in 28 years Has been put forward this idea, but it was not until 1947 by Bell Labs, leading the team Schottky invented the first transistor, which is a revolutionary invention from scratch, as was the micro-electronics development Basis. From then on, our computer was getting smaller and smaller, the computer will be able to enter millions of households, (we can look at the 46-year first computer, with the realization of tubes, speed.... 9 room occupancy)
有够长的...
Today I will introduce the summary of microelectronics, or say the integrated circuit design to you. We shall make a simple review of the microelectronics and its history of development.
Let's look at this picture. Now almost all of you have mobiles, and most of them have strong functions, being able to listen to music and radio, play games, surf the network and so on except calling and sending SMS. But see the mobiles ten years ago, they had just a single function and a big volume. You can only use them to make calls, and they were also very expensive. (ten thousand per one)
Other things are also changed. You also use digital products such as the computer and MP3. Ten years ago, memories had a little capacity, just 10M,20M..., but the price was quite high. Today's hard discs are only cost certain hundred with a large capacity. In fact, the electric equipments are more and more functional with smaller piece and lower price.
Maybe you have the question: Why do these changes take place?There are a lot of reasons, but the basic one is the development of microelectronics. The core of microelectronics technology——the development of integrated circuit technology results in these revolutional changes.
What is microelectronics? Let's see the definition. It's ——
Simply speaking, microelectronics is to make micro circuits. Just like what on the picture, electronics is the tall man while microelectronics is the short man on the right. The content is almost same, but the size is much smaller.
The kernel of microelectronics is the design of integrated circuits. The so called integrated circuit design is combining active devices(diode,transistor etc.), passive device(resistance,capacitance etc.) with their joint lines, and put them on a semiconductor bottom to form an independent integer, which can realize some circuit functions.
Then, let's have a look at the development history of the microelectronics. We can't ignore the development of transistor when reviewing microelectronics. It's the most basic unit making up the integrated circuit. The concept appeared in 1928, but until 1947, a team leaded by Schottky in Bell Laboratory just invented the first triode, which was a revolutional invention providing foundation for the future of microelectronics. From then on, our computers become much smaller, and be able to access to every family.(We can see the first computer in 1946, realized by electron tubes, the run speed...occupied 9 rooms)
Today want to be the general outline that the micro-electronics learn to perhaps say to is an integrated circuit design for what everyone introduction, we will learn the micro-electronics and the micro-electronics learn development of the history do a simple of elaborate
2, we see this picture, now the classmates probably all have a cellular phone, the cellular phone of big and parts of classmate still own very strong function, in addition to make a phone call, hair message, return can listen to music, broadcasting, play games, get to the Internet, etc., but show us before decade we usage of cellular phone, not only the physical volume be huge, and function one, can make a phone call, price is also equal expensive, (10,000 many)
3, variety of still not our cellular phone, the classmates also all use to conduct electricity a brain, mp 3 it the electronics product of type, before decade of saving machine of the capacity be also several 10,000,000,000,000, but the price be good friends with several thousand, now hard drive capacity frequently top 100 G, but want ～only several 100 pieces, actually various electric appliances be all more and more small, the function be more and more strong, price also a decline again decline.
4, everyone may ask and why will have these varieties?The reason of the noodles is a lot of here, but most root of the reason is a micro-electronics technique of development, among them micro-electronics technique of core-integrated circuit technique of development cause these revolution variety.
5, what call micro-electronics?We to take a look definition, the micro-electronics learn be-
6, simple of to say, micro-electronics' learn be the electric circuit which do a tiny view and be like an in our picture reflection of, the electronics be this Gao Ge4's man, but micro-electronics' learn is the right side this of man, contents basically about, only do of more and more small.
7, the micro-electronics learn of a core be an integrated circuit design, so-called integrated circuit design be be will have a source component(diode, transistor...etc.) with have no source component(electric resistance, electric capacity...etc.) and they of on-line together creation at semi-conductor Chen bottom top formation an independence of whole.This is whole ability realization some electric circuit function.
8, connect down, let us take a look a micro-electronics to learn of development history, please see a picture, speak of a micro-electronics to learn, we have to speak of transistor of development, the transistor can say is constitute integrated circuit of the most basic unit, have already put forward this concept in 28 years, but until 1947 from Bell Laboratories, Xiao especially the Ji lead of team invention a triode transistor, this is a revolution invention, from have, for the micro-electronics learn afterwards of development provide foundation.From now on, our calculators be just more and more small, the calculator just has opportunity to walk into thousand 10000, (we can take a look for 46 years one set calculator, use an electronics tube realization, circulate speed....Take up 9 room)
你这不是废话嘛！我要是英文学得好。。自己会翻译。。还会吃饱了撑的上网求助别人干嘛？
我觉得，你要是有能力就该自己翻译，不应该靠外力和翻译软件。
Today needing to give being that everybody introduces a microelectronics or speaking is the introduction that IC designs , we will do simple expounding of one to the history that the microelectronics and the microelectronics develop We look at 2, this photograph , schoolmates have presumedly all mobile telephone now , mobile telephone of most schoolmate owning the function very big and powerful , being able to listen to music , the broadcast , playing with game , to get on the Internet besides being able to call , sending out a short message ,and so on, lets mobile telephone, not only volume is ample , but also the function is unitary , can only call , price that we use before we take a look at 10 be also pretty expensive but, (more than 10,000) not only our mobile telephone that 3, changes, Schoolmates had used also all a computer, mp3 and the like electron product, several tens foretell front memory in 10 capacities also right away, price be close friends but several thousands, hard disk capacities mount hundred G easily now , need only but several hundreds pieces but, various electrical equipment is all more and more small in fact , the function is more and more big and powerful, price also descends repeatedly. Everybody may need to ask about 4, why to be able to have these changes? Cause of here soft and floury many, the basicest cause has been development of microelectronics technology but , development of microelectronicses technology among them core IC technology has led to these revolutionary character change. 5, what orders microelectronics woollen cloth? We come to look at one giving a definition , the microelectronics is 6, comes to say simplely , the microelectronics is to be used for the microcosmic circuit , right away such as our what photograph middle reports,the electronics is this tall man , the microelectronics is that on the right this short man , content are mainly about the same but , just composes. The microelectronics one core it is IC to design that 7, so-called IC designs the Jiu Shi Jiu Shi general active component (diode , transistor etc.) and passive component (electric resistance , capacitance etc.) and their company line makes a independent overall taking form on semiconductor underlayment together. This entirety is therefore likely to realize a few circuit functions. Then 8,lets us take a look at the microelectronics development history , look at a photograph please, mentions a microelectronics, we have to mention development of transistor , the transistor so to speak is to compose the most fundamental IC unit, before 28 have brought forward this concept right away already, but until reason Bell laboratory in 1947, the team that Schottky leads has invented the first audion , this has been a revolutionary character invention , has grown out of nothing, development of afterwards has provided a basis to the microelectronics. Herefrom, our computer is just now more and more small , the computer gets chance to walk into huge numbers of families just now (, we can take a look at the first computer of 46 , use electron tube to come true , to run speed. . . . Occupy 9 rooms)
