   Can 7nm chips be fabricated without EUV lithography?

   • As nodes get smaller and smaller, the need for EUV lithography gets more and more important. However, 7nm features can still be fabricated without EUV. It adds a lot of complexity to the design, but 7nm chips can be fabricated with earlier, DUV technology. DUV tools are more widely accessible and have been in the market for many years.

   Can China make a lithography chip on a 7nm node?

   • Even before that, the US had successfully pressured the Dutch government to block ASML — the only provider of extreme ultraviolet light (EUV) lithography machines used to make chips on leading-edge nodes, such as 7nm — from selling such systems to China. Despite these efforts, China has apparently managed to create finished products on a 7nm node.

   Can a 7nm chip be made in China?

   • Despite these efforts, China has apparently managed to create finished products on a 7nm node. One reason SMIC can do this is because EUV systems are not mandatory when crafting leading-edge chips. Instead, the chipmaker is likely using an older generation of lithography machines, called deep ultraviolet lithography (DUV), to manufacture 7nm chips.

   Nov 5, 2022 · The N7+ node is TSMC's first process technology to adopt EUV lithography. It is unrelated to both the N7 and N7P processes, and is not IP-compatible with either, requiring re-implementation (new physical layout and validation).
