It is reported that China will be able to put into production the fully self-developed 28nm process this year, and next year it will put into production the fully self-developed 14nm FinFET process. The production of advanced processes may help Huawei solve chip manufacturing problems.
In fact, China’s two major chip manufacturers, SMIC and Shanghai Huahong, have already put into production the 14nm FinFET process, but they also needed to rely on some technologies supplied by the United States. It is because of these American technologies that they cannot produce HiSilicon for Huawei Kirin chip.
Industry insiders now point out that China has successfully developed a completely self-developed 28nm process, which means that in just over a year, China has made significant progress in independent process research and development. Relying on existing technologies, the 14nm FinFET process will be autonomous next year. It is also possible.
In fact, not only is China promoting the autonomy of the chip manufacturing process and getting rid of its dependence on the outside, but the two most technologically advanced chip foundries in the world are also actively promoting autonomy. Due to disputes with Japanese material suppliers, Samsung has promoted the independent research and development of photoresist and increased the proportion of independent technology in the chip manufacturing process.
In the past few years, TSMC has also been increasing the proportion of independent research and development technology and reducing the proportion of American technology. In 2019, TSMC firmly stated that it can manufacture Kirin 990 chips for Huawei with 7nm EUV. The reason is that the proportion of technology from the United States is as low as Within 10%, but in 2020, the United States revised the requirements again, emphasizing that as long as American technology is used, it cannot OEM chips for Huawei, and TSMC cannot OEM Kirin series chips.
In the face of the US practice, many chip foundries naturally strive to promote independent technology research and development, and China’s chip foundries are even more responsible for the development of independent chips. They actively promote independent technology research and development, and now they have finally achieved the full 28nm process. Autonomous, and proposed to achieve complete autonomy of the 14nm process by next year.
The ability of Chinese chip manufacturers to realize the autonomy of chip manufacturing technology is also inseparable from the efforts of the chip manufacturing industry chain in mainland China. In recent years, China has recognized the importance of chip manufacturing and has begun to promote the autonomy of the entire industry chain. It should also be the progress of the independence of the industrial chain, which has helped chip manufacturers to achieve complete technical independence.
Although domestic chip companies put into production the fully autonomous 14nm FinFET next year, there is still a big gap between them and the global advanced technology level. TSMC and Samsung are expected to put into production the 3nm process next year, but this is of great significance to the Chinese chip industry. After all, China is the world’s largest manufacturing country and has a huge demand for chips. Except for some advanced technology industries that require the most advanced manufacturing processes, most other industries only need to use mature technology manufacturing processes.
For Huawei, it can also produce products that meet market demand with mature process technology, such as Huawei’s TV chips, automotive chip series, and even the mainstream process of automotive chips is still 28nm. Huawei has actively entered the automotive chip industry, so Huawei this year The 28nm process can produce automotive chips, and next year, the 14nm FinFET process will be used to produce automotive chips.
Huawei has previously stated that even if it cannot find a chip foundry to produce chips for the time being, it will not stop chip research and development. Now, with the commissioning of the independent domestic chip manufacturing process, it may be ushering in a turning point. The Kirin series of chips will reappear and participate in Competition in the global chip market.
