Semiconductor manufacturing has been the latest victim of the recent trade war between China and the United States. With the US imposing sanctions on Chinese manufacturers, they have not been able to use any US technology without the approval of the US government. That has caused many companies to lose customers and switch their preferred foundry. The US government has also decided to sanction a Chinese company Huawei from accessing any US-technology-based manufacturing facilities, thus has prevented the Chinese company from manufacturing its chips in the facilities of TSMC. Left without almost any way to keep up with the latest semiconductor technology, Huawei is reportedly working on its own manufacturing facilities.
According to the Financial Times, Huawei is about to enter domestic silicon production with its partner company Shanghai IC R&D. And a big note here is that the manufacturing facility will not use any US technology. The production is allegedly going to start as soon as the end of this year, and the first process that will come out the door will be a rather outdated 45 nm node. The company is expecting to move on to a more advanced 28 nm node by the end of next year. While the capacities are unknown, we can assume that it will be enough for the company's purposes. With this move, Huawei will be 100% independent from any US influence and will own the complete vector of software and hardware, that is a custom made design by the company.
The steps against Huawei have accelerated Chinese IT developments. China has her own money transfer systems - what was seen as strategically important by the government. However anything else was not - China could have used US IT tech for a few decades longer. Now China will develop her own IT and will use that. The same way they use their own money transfer systems and not the US money transfer systems.
