Bitcoin 7 nano chip

1.

Chips exist in some of our daily electronic devices, such as mobile phones, computers. The performance of 14 nm chips is much better than that of 7 nm chips. However, this improvement can not be perceived by ordinary users. Only those applications or devices that need to consume computing power will feel it

The difference between 14 nm chip and 7 nm chip

although a chip uses nanometer to express its magnitude. But the smaller the nano number, the more transistors it contains. The more transistors it contains, the faster its processing speed will be. So the difference between 14 nm chip and 7 nm chip is that 14 nm chip contains less transistors per unit area than 7 nm chip. For example, there will be floor heating in the north, and the more heating pipes per unit area, the warmer it will be. This is a truth. The more transistors per unit area of the chip, the faster the computing speed

What do you know about 14nm chip and 7Nm chip? Welcome to comment

2. The so-called 7Nm chip means that the linewidth of the chip process is 7Nm. How small is 7 nanometers? A hair is about 0.1 mm in diameter, and 7 nm is equivalent to one tenth of a hair
the general process of inquiry begins with finding and asking questions. After finding the questions, make hypotheses about the answers to the questions according to your existing knowledge and life experience. Design the scheme of inquiry, including the selection of materials, design methods and steps, etc. according to the scheme of inquiry, get the results, and then analyze whether the results are consistent with the hypotheses, Therefore, after drawing a conclusion, we need to reflect on the whole process of inquiry. The general methods and steps of inquiry experiment are as follows: putting forward problems, making assumptions, making plans, implementing plans, drawing conclusions, and so on Expression and communication.
the common methods of scientific inquiry include observation, experiment, investigation and data analysis.
observation is a basic method of scientific inquiry. Scientific observation can be done directly with the naked eye, with the help of magnifying glass, microscope and other instruments, or with the help of cameras, video recorders, cameras and other tools, Sometimes measurement is needed; The observation should be comprehensive, meticulous, realistic and recorded in time; Plan and be patient; We should think positively and record in time; The design of the experimental scheme should be closely around the questions and hypotheses put forward. When studying the influence of a condition on the research object, the experiment with the same conditions except for the different conditions is called control experiment; Collect information related to the problem; Making assumptions; The experimental scheme was designed; Carry out the experiment and record it; Analysis of experimental phenomena; In the process of investigation, sometimes because the scope of investigation is very large, it is necessary to select a part of the respondents as samples. In the process of investigation, it is necessary to record truthfully. The results of the investigation should be sorted out and analyzed, Sometimes it is necessary to use mathematical methods for statistics. Collecting and analyzing data is also one of the common methods of scientific inquiry. There are many ways to collect data. Go to the library to consult books and newspapers, visit relevant people, and collect data on the Internet. The forms of data include text, pictures, data, audio-visual materials, etc.

Transistor is the most basic unit of chip. It has fast response speed and high accuracy. It is used for various digital and analog functions, including amplification, switching, voltage stabilization, signal molation and oscillator, etc. Hundreds of millions or more transistor integrated circuits can be packaged in a very small area, which is the chip

with the process of the chip approaching the size of the atom, the quantum tunneling effect will become extremely easy, which will lead to a large current leakage problem. Due to the failure of dendal scaling law and the subsequent heat dissipation problem, it is more and more difficult to improve the chip clock frequency simply by recing the gate length, and manufacturers graally turn to low-frequency multi-core architecture
there may be more advanced chip manufacturing technology in the future. The above personal opinions are welcome to be criticized and corrected. Agree with me, please click like before you go, thank you! Like me, please pay attention to me, thank you again< br />

4. On August 8, 2018, big news came from Hangzhou: supercomputer chip developer Jia Nan Yun Zhi officially announced that the world's first 7-nanometer chip was successfully mass proced

you're not wrong. It's not R & D, it's not design, it's mass proction. It is understood that the first batch of 7Nm chips have been delivered by TSMC

as soon as the news came out, the science and technology circle exploded! You know, apple, Qualcomm and NVIDIA's 7Nm chips won't be put into proction until the fourth quarter or even the end of the year

this means that Chinese chips have broken through the European and American blockade in an all-round way. This is a glorious moment for Chinese chips to fight back victoriously, and also a historical moment for the development of Chinese science and technology!

5. I want to say that the first person has never studied physics, right? There are also semiconctor device physics. He talks nonsense. First of all, the same current is required for the same operation. According to what you said, the greater the resistance is, the more energy will be lost in heating if he wants to pass through the same current. Do you think it can save electricity
if you want to solve the problem, please take a look at the physics of semiconctor devices and semiconctor manufacturing technology. The change of nm number is not a simple problem of cross-sectional area, but also contains problems such as wiring. You'd better check for details yourself. It's true that you don't have enough knowledge and you don't talk about it.

6. I don't talk about the whole brain, but about a neuron. Its working principle is not completely clear. The brain structure is much more complex than the chip. The number of brain neurons is hundreds of billions, and one neuron is complex enough. The chip is just billions of transistors

1 nm = 10 to the minus 9 square meters. The length unit is the same as centimeter, decimeter and meter. It refers to the width of the wires between transistors on the chip. It's the etching size of the processor

is the size of a chip on which the user can carve a unit of transistor. The mobile phone processor is different from the general computer processor. The size of a mobile phone is quite limited. The smaller the etching size is, the more computing units there are in the same size processor, and the stronger the performance is

the micron of manufacturing process is the distance between circuits in IC. The trend of manufacturing technology is to develop in the direction of higher density. The higher the density of IC circuit design, means that in the same size area of IC, can have a higher density, more complex circuit design

< H2 > extended data:

programmable nano processor structure

the area of a single transistor on the prototype chip is 1.9 square microns, and the area of a single transistor on the chip manufactured by 32nm CMOS technology is more than 20 times that of 0.09 square microns

contains multiple "tile" moles, each mole contains 496 programmable transistors, all composed of 10 nm thick germanium nanowires. The result of this research is to use these "tiles" to design, build and use programmable chips, whose replicability and scalability are quite different from traditional semiconctor manufacturing methods

this prototype processor represents a major breakthrough in assembling complex computing circuits with synthetic nano scale components. At the same time, the processor also has programmable features, which can realize basic mathematical logic operations such as addition, subtraction, multiplication, division and latch

8. At present, we can't do it. The top machine of lithography is from Holland. There is a high threshold in this field. Without generations of technology accumulation, we can't make such a machine. Moreover, this lithography machine is also made of the world's top accessories, including the United States and Japan... In a word, this lithography machine is the top technology on the earth at present. It is the technological crystallization of the whole world. It can't be made by one country.

9. This is good news. After mass proction, the most important thing is to look forward to landing and improving the yield so as to support the breakthrough in the next stage.
we can't comment on the situation of no longer limited

10. Nanometer is one of the units of length
