preface
With the development of science and technology, the electronic products we use are becoming more and more compact, from large back TVs to tablets, from "big brother" mobile phones to smart phones that can be held in the palm of your hand, these technology products can even enhance performance in the case of reducing the size, and the progress of such technology is all thanks to the development of chip technology.
In the operation of modern society, chips can have a pivotal position, such a small size, but can store and run a large amount of data, from passenger aircraft, military radars, to smart phones, tablet computers, without exception need the participation of this small new chip.
For many years, the world's most advanced chip technology has been firmly in the hands of foreign companies, and the performance of China's self-developed chips is slightly inferior to the world's top chip level, so whenever China needs chips, it can only be solved through a large number of imports.
China is vast and populous, in contrast to the smartphone industry is also very large, the production of smart phones can not be separated from chips, according to statistics, the mainland annual cost of imported chips exceeds 200 billion US dollars.
What is the concept of $200 billion? Let's say that this money will be used to buy aircraft carriers, which is enough to buy 20 medium aircraft carriers.
In this regard, many netizens can't help but sigh, instead of spending such a large amount of money to buy foreign chips, why doesn't the mainland develop its own domestic chips?
In fact, the road of self-research of Chinese chips has never stopped...
The "scientific and technological blockade" cannot bring down Chinese scientists
With the continuation of the Sino-US trade war, the United States also uses chips as a weapon to severely suppress our China, the United States thinks that it can take this opportunity to jam our "neck", but they have always underestimated the determination of the sons and daughters of China.
With the explosion of the Hiroshima nuclear bomb, the end of World War II, the bipolar pattern was formed, at this time the world was very afraid of the nuclear bomb as a weapon, and during the Cold War, countries began to develop nuclear weapons in order not to be affected by the "nuclear threat" to maintain national security.
In the 60s of the last century, the Soviet Union withdrew scientists who came to the aid of the mainland and took all the research materials with them, and at that time the whole world did not believe that the mainland could independently develop an atomic bomb.
But even so, in the face of scientific and technological blockade, mainland scientists successfully detonated China's first atomic bomb in October 1964 through round-the-clock research and development, and the spectacular scene impressed us all over the world.
Similarly, since the last century, the mainland has not had its own aircraft carrier fleet, and in the face of the US aircraft carrier group's "swagger" in the mainland Taiwan Strait and the South China Sea, we have no way to do so.
Thanks to the collapse of the Soviet Union, the mainland purchased the "Varyag", which was not completed at that time, and towed it back to China for transformation and research and development, and the "Liaoning" began to officially enter service in September 2012, and after learning the complete construction process, the construction of the "Shandong" and "Fujian" was completed in 2019 and 2022, marking the mainland's entry into the queue of aircraft carrier powers.
And now, with the coming to power of Trump and Biden, the United States has never stopped suppressing China's science and technology, especially in chip-related fields, they believe that we cannot independently develop domestic chips in the case of a technological blockade, but once again, the Americans underestimated our determination...
Huawei's "Nirvana Rebirth"
In 2018, Trump came to power, in order to maintain the hegemonic position of the United States, so he decided to suppress China's economy, science and technology and other fields, among which the most distressed 1.4 billion people are the sanctions against Huawei.
The United States falsely claimed that the use of Huawei's mobile phones would leak state secrets, illegally collect user data and other reasons, took Huawei to court, and used extremely severe means to crack down on China's Huawei, and finally Huawei's US branch could not withstand the pressure and left the US market.
Driving Huawei back to China is far from his goal, and the US government is afraid that Chinese technology companies represented by Huawei will surpass American technology in the future, and then affect the status of US technology hegemony.
As a result, until now, the United States has carried out several strikes against China's Huawei: illegally detaining Meng Wanzhou, prohibiting American companies from providing software support for Huawei, prohibiting countries around the world from providing chip imports to China, and prohibiting countries from providing Huawei with semiconductor technology and parts supply.
For a period of time, due to extreme suppression, Huawei once fell into the dilemma of bankruptcy, but fortunately, Chinese and Huawei heart-to-heart, a large number of purchases and purchases of Huawei mobile phones, but also thanks to this Huawei can finally be reborn in adversity, return to the public's vision, through the Android system to fully upgrade to HarmonyOS Hongmeng system, once again to the world to show the resilience of domestic enterprises.
At the same time, the Chinese government has also spent a lot of money to support Huawei's self-research projects for chips, and it can be said that Huawei represents the top technology of Chinese enterprises, and if it can stabilize Huawei's confidence, it can stabilize the confidence of all Chinese enterprises in scientific and technological development.
Meng Wanzhou, who was illegally detained by the United States and is now the rotating chairman of Huawei, mentioned at a global analysis conference that Huawei's current investment in global digital upgrading will exceed $2.34 trillion in 2026, and she also stressed that Huawei will continue to develop independently and gradually break down technical barriers from Western groups.
This press conference, like a heavy punch, hit the heart of the Americans.
With the unremitting efforts of Huawei's scientific research team, Huawei was reborn like a phoenix and returned to the world's vision, when Huawei chips were suppressed and had to withdraw from the international market, and now Huawei's scientists have overcome difficulties through unremitting efforts, and "China Chip" also came into being.
Prior to this, China had developed a super-powerful chip of its own, and the technology contained in this chip is currently mastered by only three countries.
55nm phase change memory chip is here!
In 2019, China's strongest chip 55nm phase change memory chip came out, his operating efficiency is far more than thousands of times that of traditional chips, and its service life is longer than before, because of its excellent performance, when China's self-research came out, it attracted the attention of people from all walks of life around the world.
In 2017, Dr. Song Zhitang, a laboratory director of the Chinese Academy of Sciences, led a scientific research team of dozens of people to make a major breakthrough in the research of new phase change storage materials, and proposed a high-speed phase change storage technology for the first time, which also marked that China has embarked on the road of independent research of high-speed phase change materials.
In August 2019, Jiangsu Times Allcore Company mentioned at a press conference that the company will officially launch a 2-megabit programmable read-only phase change memory "Puyuan 611", which also proves that China's self-developed phase change storage technology has made a new breakthrough.
Phase change memory stores data by using a special compound that maintains the difference in conductivity between crystalline and amorphous states when power is applied.
Typically, phase change memory is an information storage device that uses the difference in conductivity of chalcogenide compounds between crystalline and amorphous states to store data.
Compared with traditional storage methods, this storage method has the advantages of non-volatile, small process size, high storage density, long service life and fast read and write speed.
As a memory, its three most critical items are: read, store, take out, to put it bluntly, take it out, save it, and put it in. How many scientists have been working in the chip field for several years in order to efficiently use these three steps to extend and expand.
Although phase change memory chips are not mature in the mainland, this is still a heavy news for China's integrated circuits, which marks that China is the third country after the United States and South Korea to successfully master phase change storage technology, which also marks that China has made a breakthrough in a field of science and technology, getting rid of the blockade of Western blocs and has its own intellectual property rights.
Is the "smaller" the better?
In recent years, many people may be advocating 4nm, 3nm semiconductor chips, saying that the smaller the more advanced, the smaller and more developed, saying that the DUV lithography machine is currently the "most advanced" lithography machine.
In fact, in the current chip industry, 90% of the world's chips are still larger than 28nm semiconductor chips, at present, China's Huawei has also produced 14nm level semiconductor chips, it can be said that most of the chip use scenarios, with the mainland's self-research capabilities have been able to fully meet most of the needs, especially in the military field.
It is very contrary to common sense that in fact, military chips are not the "most advanced" chips that everyone thinks, and many fighters and even aviation rockets use chips, most of the chip specifications used are only within 65nm process, and their operating speed is only one-tenth of the most advanced mobile phone graphics chips.
It is true that the research and development direction of military chips is more in the processing of technologies such as high temperature resistance, low temperature resistance, anti-interference and anti-vibration, and can be used in terms of data operation.
Secondly, most of the civilian equipment, including washing machines, refrigerators, televisions and even new energy vehicles, use no less than 28nm semiconductor chips, and China can also achieve mass production, and the most advanced batch of chips are only loaded in new smartphones.
epilogue
Domestic chips again and again technological breakthroughs, will inevitably make us excited, but from the "apex" of semiconductor chips, the mainland still has a long distance, and the United States-led Western bloc, through the scientific and technological blockade of the mainland, also made us once again aware of the importance of "domestic", but fortunately, the attitude of Chinese scientists to self-improvement has not changed, at that time the older generation of scientists broke through the technical blockade of nuclear bombs and aircraft carriers, and now, I believe that this generation of scientists can also break through the technical blockade of chips, truly realize the self-developed "Chinese core"!
