Handcrafted 085nm chip, performance surpasses Intel?Don't listen to the nonsense of netizens
Since Huawei was sanctioned by the former United States, people have realized that China's semiconductor industry is not as strong as imagined. Taking Huawei as an example, although Huawei has successfully designed the Kirin chip, the Kirin chip cannot be produced without TSMC foundry, which means that Huawei can only buy Qualcomm chips and launch a 4G version of Huawei mobile phones.
In the face of the unreasonable suppression of the former United States, Chinese technology companies have caught up, breaking down one technical barrier after another, and launching one new technology after another. For example, SMIC has mastered the mature 28-nanometer chip manufacturing process, Loongson Zhongke has designed the Loongson 3A6000 chip, and JCET has conquered the 4-nanometer chip packaging technology.
Although our country has made remarkable achievements in the field of semiconductors, we still have a big gap compared with the former United States and other countries.
It's not terrible to have a gap, we just need to keep trying. I am afraid that some people will confuse the public and deliberately exaggerate our achievements in the semiconductor field, which is not conducive to the development of our semiconductor industry.
Some time ago, there was news circulating on the Internet that China's top academic institutions have roughly hand-built 0The 85-nanometer chip surpasses Intel's chips in terms of performance, and it also does not require a lithography machine.
When I saw this news, I was both angry and helpless. Angry because these people have subverted the current scientific and technological common sense, and helpless because their original intentions are good, they hope that domestic chips cannot be eliminated.
Obviously, handmade 085nm chips are very unrealistic, why?
First of all, chip manufacturing requires a high-level EUV lithography machine, and the most advanced EUV lithography machine in the world is currently produced by the Dutch company ASML. The EUV lithography machine of the Dutch company ASML is not yet able to produce chips below 3 nanometers, so it cannot yet produce 085 nanometer chips.
Secondly, the world's most advanced chip producer is our own TSMC. At present, TSMC has been able to mass-produce 4-nanometer chips, such as Tengjie 9200, Snapdragon 8Gen2 and Apple A16, which are all 4-nanometer chips.
Moreover, TSMC has mastered the mature production process of 3nm chips, so it is not difficult to produce 3nm chips, that is to say, the most cutting-edge chips that can be produced at present are also at the 3nm process level, so they rely on manual manufacturing 085nm chip, this is undoubtedly a fantasy.
Finally, I searched the Internet for the academy about handicraft 0The 85nm chip reported relevant information, and after a long search, I didn't find any relevant information. Therefore, I think this news is a fabrication by netizens and does not stand up to scrutiny.
In fact, hand-crafting chips is nothing new. As early as 20 years ago, chip leader Chen Jin claimed to have developed it"Hanxin No. 1"DSP chip was recognized by professionals in the industry at that time. For a time, many people thought that China's integrated circuit technology had reached the world-class level.
It's a pity"Hanxin No. 1"It was not developed by Chen Jin, but polished by him with the Motorola Freescale 568000 chip he bought. When Chen Jin's lie was exposed, many people had great illusions about it, which also indirectly slowed down the development process of China's PC chips.
Fortunately, Loongson Zhongke lived up to expectations and launched the self-developed Loongson 3A chip series, which made China's PC chips close to the level of the world's most common chips.
Looking back on the past three years, China's semiconductor industry has indeed developed rapidly, but there are also people who fish in troubled waters. These people took advantage of state subsidies to build one semiconductor factory after another, promising to push China's semiconductor industry to a higher level, but these companies only cared about their immediate interests and did not make long-term plans, and eventually withdrew from the semiconductor market.
According to relevant statistics, by 2022, 5,746 semiconductor companies in China will be closed, including many large enterprises with an investment of more than 100 billion.
It can be seen that the development of semiconductor enterprises should be taken step by step, and they cannot be ambitious, so they are handmade 0The topic of 85-nanometer chips can also be put on hold.
