Why is there no self developed chip in China? Which foreign countries have independent research and

<> countries and regions that can manufacture chips.

There are more than a dozen, but the only countries that can design and manufacture high-end chips are the United States, the Netherlands, and Japan. Whether an etching machine smaller than 14 nanometers can be manufactured independently is a measure mark. China also has it, and the military aerospace industry has always been a domestic chip.

Japan, South Korea, and the United Kingdom all have them. Chips are also not patented by the United States, and other countries are only trying to reduce R&D investment.

Take a shortcut to your purchase.

Many countries have their own chips, but the strength of chip functions and the integrity of the chip industry are the strength of their own independent development capabilities. At present, the problem to be solved by China's chips is the integrity of the industry, development capabilities and independent intellectual property rights.

and so on.

Photoetching. It is the link between manufacturing and design. Many of these processes are carried out in independent factories, and the equipment used also needs to be manufactured in specialized equipment factories; The materials used include hundreds of specialty gases, liquids, and targets.

All need for a specialized chemical industry. In addition, the production of integrated circuits is carried out in ultra-clean rooms, so systems such as exhaust air and air purification are also required.

The point is that the Chinese are the most powerful among the people who have created the existing facts and the status quo。Everyone says how hard it is to build a chip, but the top chip is made by TSMC.

Of course, it was made for him, so that the international leading chip design technology owned by domestic and foreign companies, including Huawei, has become a high-end chip.

China is the only country in the world that can manufacture the world's top high-end chips, and in terms of chip design, Huawei HiSilicon is the world's leading chip design capability.

and other companies have the manufacturing capacity of the world's most high-end chips, especially TSMC, due to the whole chip industry chain.

The technology we rely on, especially the top technology, basically comes from the United States, which makes us still subject to the United States in the chip semiconductor industry despite having the world's most advanced chip semiconductor industry chain, so that companies in our own country are unable to provide chip manufacturing OEM production for their own enterprises due to the restrictions of the United States.

Because China's scientific and technological development is not strong enough, there are still many shortcomings in the field of core technology, especially in this area of talent is still insufficient. The United States, the United Kingdom, the Netherlands, France, and Canada all have independent research and development chips.

Because in this industry, our country has not been able to break through the high-end chip industry. At present, the countries that can manufacture are the United States, the United Kingdom and other developed countries in Europe and the United States.

The reasons why China can't make chips are as follows:

1. There is no high-end lithography machine.

The lithography machine is the core equipment for making chips, and the performance of the chip is determined by the accuracy of the lithography machine.

2. Lack of talent.

The state has funds to support studying abroad, but not all of those who study abroad have achieved academic success, and some have become foreign nationals.

3. Foreign chip technology blockade.

The United States introduced the "chip ban" because the development of China's science and technology has threatened the United States.

Classification of chips.

There are many ways to classify integrated circuits, which can be divided into: analog integrated circuits, digital integrated circuits and mixed-signal integrated circuits (analog and digital on the same chip) according to whether the circuit is analog or digital.

Digital integrated circuits can contain anything, with logic gates, flip-flops, multitaskers, and other circuits ranging from a few thousand to millions in a few square millimeters. The small size of these circuits allows for higher speeds, lower power consumption (see Low-Power Design) and reduced manufacturing costs compared to board-level integration. These digital ICs, represented by microprocessors, digital signal processors, and microcontrollers, operate in binary and process 1 and 0 signals.

Analog integrated circuits include, such as sensors, power control circuits, and op amps, that process analog signals. Complete the functions of amplification, filtering, demodulation, mixing, etc. By using analog integrated circuits with good characteristics designed by experts, the burden on circuit designers is reduced, and there is no need to design from the basic transistors.

1. Japan. Toshiba, Japan's largest semiconductor manufacturer and the second largest integrated motor manufacturer, is part of the Mitsui Group. Founded in July 1875 as Tokyo Shibaura Electric Co., Ltd., the company was formed in 1939 by the merger of Tokyo Electric Co., Ltd. and Shibaura Manufacturing Co., Ltd.

2. Singapore.

Nanyang Technological University (NTU) in Singapore has developed a low-cost cell-cultured biochip that will allow researchers to determine more quickly whether a patient is infected with a new influenza virus.

3. The United States. Qualcomm is the world's leading wireless technology innovator, transforming the way the world connects, computes and communicates. Connecting mobile phones to the Internet, Qualcomm's invention ushered in the era of mobile Internet.

4. China. Chinese scientists have successfully developed a new generation of general-purpose processor chips, Loongson 2E, whose performance has reached the level of mid-range Pentium processors.

5. South Korea. Samsung Group is the largest multinational conglomerate in South Korea, Samsung Group includes many international subsidiaries, its subsidiaries are: Samsung Electronics, Samsung C&T, Samsung Life Insurance, etc., and its business involves electronics, finance, machinery, chemistry and many other fields.

Among them, Samsung Semiconductor, a subsidiary of Samsung Electronics, is the world's largest memory chip manufacturer whose main business is the production of SD cards.

Countries that can produce computer CPUs are the United States, China, and the following references:

1.United States.

AMD designs and manufactures innovative microprocessors for the computer, communications, and consumer electronics industries. Intel is an American company that mainly manufactures CPU processors. It is the world's largest manufacturer of PC components and CPUs.

Intel provides key components for the computer industry, including high-performance microprocessors, chipsets, cards, systems, and software.

2.China.

Loongson" series chips are designed and developed by the Chinese Academy of Sciences, Loongson 3 series is a multi-core processor, suitable for high-performance computers, servers and high-end desktop applications, with high bandwidth, high performance, low power consumption and other characteristics. The Loongson 3A3000 383000 processor adopts an independently designed microstructure, and the main frequency can reach more than GHz.

Any country can manufacture chips, mainly depending on what kind of chip you are talking about, different chips require different technologies, advanced ones must require high technology, and countries without technology can't make them. CPUs like computers can be produced in a few countries.

Dear, <>

I am glad to answer for you whether China's chip development road chooses independent research and development or continues to rely on imported shirts? Dear, <>

Hello, China's chip development road is to choose independent research and development or continue to rely on the recent "people**" said that domestic chips must unswervingly take the road of independent research and development. Friends who know the chip field should know that China's chip technology is relatively backward compared with Western countries. Chips occupy an important position in the field of science and technology, and chips are the soul of electronic devices.

In recent years, China has been working hard in this field, focusing on cultivating talents in this field. With a large amount of capital investment and the perseverance and hard work of many scientific researchers, we have done our best to quickly integrate with Western countries in this field. For the development of domestic chips, "People's **" has officially stated that it is necessary to unswervingly take the road of independent research and development, but the research and development of chips is a difficult road, and the production of chips is a huge and hidden project.

China's goal has always been to realize the localization of chips, but China has a big gap in the field of chips, and many high-end equipment is not available. It can be said that it is very difficult to do it from scratch. The road ahead is long, but for our country it is only a matter of time.

As a representative of the company's independent research and development of chips, Huawei also said in an interview that it only focused on chip R&D and design, and did not pay attention to chip manufacturing technology, which led to the current "core shortage" situation. However, Huawei didn't give up. The most important manufacturing issue is high-end lithography equipment.

As long as there is a breakthrough in lithography technology, the localization of chips will soon be realized! Although we are innovating on our own, it doesn't mean that we have to close our doors to do scientific research. China must build a strong or distressed ecosystem to achieve multiple compatibility.

We must continue to optimize the system, develop our strengths and avoid our weaknesses, and master the core technology in this field to have a leading edge. This is also a principle that many state-owned enterprises in our country have consistently adhered to. Today's China has manufacturing advantages, large-scale market advantages, and a strong R&D team.

As long as we have a firm goal and perseverance, we will realize the localization of chips, realize our own industrial chain, and write a more magnificent new chapter in science and technology. This is not only difficult, but also inspires our fighting spirit. I am sure we will hear more good news in the near future.

Let's look forward to this day!
