ZEISS CEO confirms China has achieved 7nm chip production without EUV lithography, but warns that scaling beyond 7nm using multi-patterning DUV becomes economically unviable due to multiplying masks, process steps, and yield complexity; export controls now cover advanced DUV systems as well as EUV.

◆ ◆ The Wire takeaway
If you're selling manufacturing tools or process software to Chinese fabs, the economic floor just shifted: multi-patterning DUV stops working at scale somewhere between 7nm and 5nm, and they cannot buy the equipment that solves it. That constraint is now permanent policy.
