Chinese chipmaker Hua Hong Group readies 7nm process

Hua Hong Group‘s contract arm Huali Microelectronics is readying a 7 nm chipmaking process at a Shanghai plant, Reuters reported.

China’s largest contract chipmaker, SMIC, remains at present the only domestic producer capable of making chips with 7 nm technologies.

Details of the process and production yields remain unclear.

Huali began R&D on 7nm at its Fab 6 last year and has started test production.

Huali plans initial 7 nm capacity of a few thousand wafers per month by year-end and aims to ramp up later, sources said.

Chinese GPU designer Biren is using the 7nm line for tape-out.

🧠 Food for thought

Implications, context, and why it matters.

China’s foundries are already running beyond 100% capacity

China’s leading foundries are stretched. Hua Hong’s average capacity utilization reached 106.1%, while rival SMIC hit 93.5% 1.
Heavy local demand is driving a plan to lift advanced output at 7 nm and possibly 5 nm performance levels by five times within one to two years. That would move from under 20,000 wafers to 100,000, based on a Nikkei-cited report summarized by TrendForce (a market-research firm focused on semiconductors) 2.
Hua Hong Group’s 7 nm work stands out, yet most added capacity targets mature nodes at 28 nm and above. These nodes support automotive chips and power-management semiconductors 3.
The buildup ties to state-backed consolidation. Hua Hong Semiconductor plans to buy a controlling stake in Shanghai Huali Microelectronics (Hua Hong Group’s contract chipmaking arm), while SMIC seeks subsidiary deals to simplify governance and grow 4.

China’s push to scale up 7 nm production will reshape global supply chains

Reuters reported that questions remain about how Hua Hong reached 7 nm and which major toolmakers supplied equipment 4.
The shift could strengthen a local pipeline for U.S.-blacklisted firms such as GPU designer Biren, which lost access to Taiwan Semiconductor Manufacturing Co (TSMC). Those companies could use Chinese 7 nm lines for tape-out (the process of finalizing a chip design for manufacturing), adding demand for domestic output 4.
TrendForce expects a split market where Chinese foundries focus on local orders, while non-Chinese fabs serve customers with geopolitical or intellectual property concerns 3.
The biggest ripple may land on mature chips. More Chinese capacity at legacy nodes could push prices down and cut margins for overseas competitors that depend on those nodes 3.
