Beijing plans 12-inch wafer fab, pouring US$4.6 billion into state-backed chip project

Beijing is set to spend 33 billion yuan (US$4.6 billion) building a 12-inch wafer fabrication facility, led by state-owned enterprises and funds, marking another step in China’s efforts to boost domestic semiconductor production

Leading firms involved in the new facility include Beijing Yandong Microelectronics (YDME), which is listed on Shanghai’s Star Market, and BOE Technology, China’s top display maker.

YDME said on Saturday that it will invest 4.99 billion yuan into Beijing Electronics IC Manufacturing, the subsidiary of state-owned Beijing Electronics Holding that is behind the wafer fab project. The deal will give YDME a controlling position with a 24.95 per cent stake in the project, supported by an acting-in-concert agreement, according to a corporate filing.

In a separate filing on the same day, Shenzhen-listed BOE disclosed that it would invest 2 billion yuan for a 10 per cent stake in the project.

Other participants include affiliates of Beijing Yizhuang Investment, Beijing State-owned Capital Operation and Management, and ZGC Group. Collectively, the shareholders will contribute 20 billion yuan, with the remaining funding to be sourced from debt financing.

YDME noted in its filing that China’s integrated circuit (IC) market is expected to reach a domestic production rate of 21.2 per cent by 2026, up from 16.7 per cent in 2021. It expects a significant supply-demand gap emerging for mature nodes, with feature sizes at the 28-nanometre level or greater, and a production capacity of 370,000 wafers per month by 2027.

Compared with the Yangtze River Delta region around Shanghai, China’s chipmaking capital, Beijing lacks sufficient players in manufacturing and back-end processes such as packaging and testing. With the new project, Beijing aims to fill those gaps and enhance the city’s semiconductor industry.

The deal still requires approval from YDME shareholders and Beijing’s State-owned Assets Supervision and Administration Commission.

This year, companies including Huahong Semiconductor, China Resources Microelectronics, and Guangzhou ZenSemi have all announced progress on 12-inch wafer fabs.

Meanwhile, Semiconductor Manufacturing International Corporation, which established the mainland’s first 12-inch foundry in 2004, reported full utilisation of its 12-inch capacity in the third quarter. Revenue from 12-inch wafers accounted for 78.5 per cent of its 15.6 billion yuan total for the quarter. The company expects to release an additional 30,000 wafers per month in the fourth quarter.

Recently, Chinese chip design firms have become concerned that Taiwan Semiconductor Manufacturing Company, the world’s leading contract chipmaker, might suspend 7-nanometre node services for certain AI chip clients due to mounting pressure from the US. The Taiwanese chipmaker recently told mainland clients that it would no longer accept orders from them for advanced chips after TSMC technology was found in a product from US-sanctioned Huawei Technologies.

 
I heard rumors that initial production is expected to be at 65nm. That this fab will use only Chinese fab equipment:

Remains to be seen. But it is true that the Chinese local government at the capital in Beijing is way more demanding of use of Chinese tools and inputs than the other local governments.

370,000 wpm capacity is huge. Nexchip already has substantial capacity and they work with BOE. Makes me wonder what YDME are thinking. The article I linked to claims the fab will be used for high-density power devices, display driver ICs, power management ICs, silicon optical chips.

Yes, when I heard mature nodes I was hoping it was 28nm but it will probably be 65nm. You would think that China fabs would work together to get the best process in production led by SMIC.

SMIC also has an older fab in Beijing which probably has a high amount of Chinese fab equipment. But right now the Chinese immersion lithography machine still does not seem to have hit production. I expect it to be available in production sometime over the next two years.

Dry litho, simple masks. Pretty much what one would expect for PRC entry into the stepper market with a real fab project.
 
The PRC announced recently, just this year, the availability of the 65nm lithography machine. But they did not say who is the manufacturer. It could be SMEE but it could also be someone else. Several parameters of the machine are also unknown. For example its wph output is unknown.

There was a PRC state funded project to develop a dry lithography machine with dual wafer stage technology but it is unknown if this tool is that one or some other.

PS:
I got this straight out of YDME's website:
