TSMC Is Reportedly Skipping High-NA EUV For The A14 (1.4nm) Process; Prioritizing Cost-Efficiency Over Performance

It seems like the Taiwan giant won't be jumping onto the High-NA EUV bandwagon anytime soon. It has been revealed that the firm will skip the lithography for the A14 process.

TSMC Now Gets Behind The Likes of Intel Foundry When It Comes To High-NA EUV Adoption, Will Rely On Older Technologies

When adopting newer elements in semiconductors, TSMC has been a pioneer for several years, and is often the trend-setter. But now, it seems like the firm will skip using the High-NA EUV lithography tool for its A14 process, as it will rely on the more conventional 0.33-NA EUV technology. This was revealed at the NA Technology Symposium, where TSMC's SVP Kevin Zhang announced the development (via Bits & Chips). With this, it is safe to say that Intel Foundry and several DRAM manufacturers now have a "technological" edge over TSMC.

TSMC will not be using high-NA EUV lithography to pattern A14 chips, manufacturing of which is scheduled to start in 2028. From 2 nanometers to A14, we don’t have to use high-NA, but we can continue to maintain similar complexity in terms of processing steps.

Each generation of technology, we try to minimize the number of mask increases. This is very important to provide a cost-efficient solution - TSMC's Kevin Zhang

Well, the primary reason why TSMC sees high-NA as something insignificant for the A14 process is that with the relevant lithography tools, the Taiwan giant could witness up to a 2.5x rise in costs compared to traditional EUV methods, and this will ultimately make the A14 node much more expensive to produce, which means that its adoption in consumer products would get difficult. The Taiwan giant is relying on chip designs and capabilities, but this certainly doesn't mean the company won't employ high-NA EUV for future processes, as it plans to utilize it for the A14P node.

One of the other reasons attributed to high-NA driving up costs is that TSMC's A14 would require multiple masks for a single layer of chip design, and using the latest lithography tools simply means the Taiwan giant is driving up costs without much benefit. Instead, by focusing on 0.33-NA EUV, TSMC can use multi-patterning techniques to maintain the same level of design complexity without needing the extreme precision of high-NA EUV, ultimately keeping production costs lower.

Interestingly, TSMC's decision to leave high-NA EUV behind does put the company behind the likes of Intel Foundry in adopting the latest tools, since Team Blue is said to utilize high-NA for the 18A process, which is expected to drop as soon as next year. With A14P targeted by 2029, TSMC would see at least a four-year delay in adopting high-NA compared to its counterparts, which could be a decision that can give competitors an edge.

 
This was actually disclosed at last year's TSMC Tech Symposium. :ROFLMAO: It is both cost and capacity. TSMC will need dozens of those HNA-EUV systems and special built fabs for HNA-EUV HVM.

"With this, it is safe to say that Intel Foundry and several DRAM manufacturers now have a "technological" edge over TSMC."

This is comical. DRAM manufacturers now have an edge over TSMC? :ROFLMAO: Do you think Muhammad Zuhair is trying to be funny or is he just clueless?

I'm sure Intel 14A and HNA-EUV will be discussed tomorrow at the Intel Foundry event so stay tuned. Exciting times in the semiconductor ecosystem, absolutely.

It's getting progressively harder to trust ~news sources.

Thank goodness SemiWiki has people like you that are steeped in various arts to help filter the noise.

Could this give edge to In memory processing? Probably helping wider adoption (hurting traditional ASIC-s). Few HNA steps plus many SAQP.

I know that it's not exactly DRAM and also probably not something author of original article meant...
 
The author of this article doesn't know what he is talking about it, as he writes that Intel 18A will use High-NA.

PPAC rules . It means TSMC counts pros and cons . After detailed consideration, TSMC believes Intel or SUMSUNG's High-NA EUV technology can't challenge its superority.

You say that as if it isn't the right PPAC choice for Intel. Also Samsung hasn't made a public commitment to anything. Not every process is the same and what works well for one process won't necessarily work for another. As an example Intel by fully embracing BSPD can use much wider metals for the same cell size so Intel is more likely to be using direct print than TSMC on a given node. high-NA direct print vs EUV double good. Double highNA vs double lowNA not so much. TSMC would seemingly be in multipatterning with or without high-NA so the value proposition might be less. But maybe not since they supposedly said A14P will use high-NA so that just doesn't really seem like a condemnation of high NA, but TSMC being conservative on cutting it in like they were with EUV and like Intel not being married to one specific approach on 14A. An older example is SAC on Intel 22nm. TSMC 20nm and 16FF didn't have SAC. Intel liked the extra EPE margin and yield this gave. TSMC got a cost saving from this and figured out how to have good yield without the SAC. And then on N7 and N5 they didn't even attempt to do SAC, but then on N3 and 10FF they did have SAC. Often times what is best changes as the requirements and capabilities change.
 
For TSMC, having a "technological advantage" which doesn't improve PPA but does increase C (and can't scale up capacity fast enough) would be pointless and counterproductive willy-waving, not a good business decision...

OTOH Intel do have a bit of a track record recently for prioritising willy-waving over good business... ;-)
