Reportedly, SMIC foundry fabricated HiSilicon 28nm chip for Huawei using a domestic line free of US technology.
近日有一张华为海思的28nm制程芯片流出，代工厂商为成都中芯国际。不要小看这一个信息，在华为遭受禁令的前提下依然能为华为代工生产芯片，那就说明在28nm制程这个节点上已经完成了技术国产化。
28nm可不是一个普通的工艺节点，这是先进工艺和成熟工艺的分水岭。台积电在2011年完成了28nm，中芯国际在2015年攻克了28nm，而现在这块芯片则是完成了“去美化”的28nm芯片，这也意味着在28nm节点上卡脖子的问题已经基本得到解决。
Huawei's self-developed 28nm chip, foundry by SMIC?Qualcomm caught off guard, not just a chip problem
2021-08-22 14:25:04 HKTHuawei is a very powerful company with its own core technology. It has developed the Kirin series of chips and the Harmony system. With its own strength, it has been loved by consumers. Huawei's self-developed chips are still very powerful, after all. There are not many companies that have self-developed chips. If foreign companies stop selling chips to domestic companies, there may be no core available, and Huawei can be completely self-sufficient.
But in order to restrict the development of domestic high-tech companies such as Huawei, a certain country implemented a chip ban, which not only restricted Huawei from purchasing chips from overseas, but also cut off the foundry channels of HiSilicon's self-developed chips. TSMC also stopped cooperation with Huawei. Although they have the technology to make chips, they can't find a suitable company for foundry. As a result, Huawei has not enough chips, and their market share has dropped a lot.
Ren Zhengfei, the founder of Huawei, said in an interview that HiSilicon can design excellent chips, but the domestic market has insufficient manufacturing capabilities, and they cannot find a suitable contract processing company. Yu Chengdong also expressed regret that he did not place heavy assets. Chip manufacturing is included in the development plan.
In fact, Huawei's restriction is not necessarily a bad thing. This can affect them in a short period of time, but in the long run, it will drive the comprehensive high-end development of China Chip and make the development of China's semiconductor industry better and better. After all, there is pressure. With motivation, the domestic market is constantly improving the shortcomings of chip manufacturing, striving to no longer be controlled by others in the future.
SMIC is a very powerful foundry company. Although it is not as good as TSMC and other companies for the time being, SMIC's progress is still very obvious. It only took about 3 years to progress from 90nm chip process to 14nm. At the level of the manufacturing process, 7nm has also completed the technological development, and the yield rate is still very high.
It is worth noting that I have developed a 28nm chip. This chip is likely to be foundry by SMIC, but this chip is not a 5nm process 5G mobile chip like Kirin 9000, but an OLED driver chip with only 28nm process. Qualcomm was caught off guard. After all, Qualcomm's Snapdragon series chips and Huawei's Kirin series chips are competitors. After Huawei gains an advantage, it is not a good thing for Qualcomm.
If Huawei and SMIC cooperate, it is not just a problem of chip breakthroughs, it can be said to be a mutually beneficial and win-win thing, but some netizens have also raised questions, that is why it is not the 5nm that is urgently needed for mobile phones, but from OLED What about the driver chip? South Korean companies occupy a relatively high market share in this field. Domestic OLED driver chips are mainly imported. This time the chip breakthrough will increase the domestic market share.
If SMIC can OEM for Huawei, then its production line will be upgraded. Huawei's breakthrough not only means its own achievements on chips, but also represents the progress of the domestic semiconductor industry, and the significance is still relatively large. of. In fact, the development of our manufacturing industry has gradually become a trend, and the popularity in the future is likely to surpass that of light asset industries such as the Internet and live streaming.
