The news of the suspension of production of the central chip at 14nm has recently sparked industry concern, and foreign media have also stated that the United States' restrictions on central chips have been effective.

The US has recently increased its sanctions on the central chip, particularly prohibiting its use of US software and equipment. This poses greater challenges for domestic chip manufacturers, and companies need to solve more problems.

As is well known, the chip dispute between China and the United States is fierce, and Huawei's performance has significantly declined due to the US chip breakage for many years. And the situation of the central chip has changed this time, what is the reason for the 14nm emergency stop?

As a leader in China's chip manufacturing industry, Central Chip has been committed to narrowing the gap with the global advanced level.

Due to external and internal conditions, the company's development path is not smooth. In fact, the US government's crackdown on domestic industries has not stopped,The United States, the Netherlands, and Japan have reached a tripartite agreement to restrict the export of some advanced chip manufacturing equipment to the mainland, which has caused numerous difficulties for the development of various domestic chip manufacturers. They have also adjusted their focus from 7nm to 14nm.

As a leading enterprise in China's chip foundry industry, Central Chip achieved the mass production target of 14nm in September last year.

Recently, it was found that the company's official website has removed 14nm information, leaving only 28nm. This change has sparked doubts and concerns from the outside world. Some foreign media even believe that this is the result of US export controls to China, which means that the central chip is no longer able to continue producing 14nm and has to abandon this advanced process.

The official has not officially announced the reason for the removal of 14nm, nor has it stated its plan to abandon the 14nm process. It is possible that due to commercial confidentiality or other considerations, the 14nm information will not be displayed to the public temporarily. Even if the US strengthens its export controls to China, we will not easily abandon the 14nm process.

As a leader in the global chip manufacturing industry, central chip has always been trying the latest chip manufacturing technologies. 14nm is a key field in chip technology and an important direction for the future chip manufacturing industry.

The global changes are not only related to external environment and internal pressure, but also to the overall situation of China's chip manufacturing industry. Currently, China's chip manufacturing industry is undergoing reforms, striving to accelerate the development of the chip manufacturing industry, enhance the technical level and market competitiveness of the entire industry.But in the global market, China's chip manufacturing industry still has to deal with many problems and difficulties, such as technical barriers, market share and Human capital flight.

Since the US government implemented the ban, Chinese enterprises have deeply realized the danger of relying on foreign technology. The path of compradors is no longer feasible. Chinese enterprises can only make a difference in the semiconductor industry by breaking away from their dependence on foreign technology. Chinese companies must develop their own EUV lithography machines to achieve self-sufficiency in order to gain a foothold in global competition.

Compared to advanced chipsCompared with emerging chips, existing chips not only have higher stability, yield, and level, but also have lower prices. And more importantly, existing chips can be applied in multiple fields to meet the needs of multiple industries and aspects. That is to say, as long as the production of existing chips is achieved, there is no need to be under the control of the United States anymore.

In the face of competition and pressure in the international chip market, the domestic chip industry has also made corresponding adjustments and responses. On the one hand, the domestic chip industry has not blindly pursued technological breakthroughs in high-end chips, but has appropriately slowed down the research and development progress of high-end chips based on its own strength and needs, avoiding wasting resources and time.

On the other hand, the domestic chip industry has not given up on the pursuit of high-end chip technology. Instead, on the basis of ensuring stable chip technology level and quality, it continues to invest more funds, talents, and energy to improve and innovate existing chip technology, enhance chip performance and efficiency.

This "two handed" strategy not only reflects the rationality and practicality of the domestic chip industry, but also demonstrates the confidence and determination of the domestic chip industry. More resources and talents have been invested in the technological improvement of stable chips, and more energy, funds, and manpower have been invested in the research and development of existing chips.

Central chip plans to build four new 12nm towers in 2023Silicon wafer production lineAfter completion, these production lines will mainly be used to produce 28nm.

After these four silicon crystal factories are put into use, their monthly production can reach 360000 pieces.The official statement states that the central chip has strong competitiveness in the existing chip field, with a yield rate of 95% -100% that is far higher than the industry average level.
