TechPowerUp - Samsung Working on Attracting more Foundry Customers by Improving Customer Structure and Process Node Breakthroughs
 
“Samsung is by far Samsung's largest foundry customer, but now it seems like the company wants to gain more customers to help pay for the costs of operating a foundry. Samsung was part of the Common Platform technology alliance together with GlobalFoundries and IBM, which allowed companies to almost pick either foundry based on a common design kit and common process technologies. It made Samsung an attractive foundry option, but the alliance didn't last.
 
Nvidia gave Samsung a try with Ampere and there were a lot of reports of yield issues and what not early on. This seems to have persuaded Nvidia to move back to TSMC for Lovelace and Hopper, which is a big loss for Samsung. This was a wakeup call for Samsung, as the company is apparently looking at making some internal changes to its customer structure so it can handle third party customers in a better way.
 
Samsung is ready to start producing chips on its 4 nm node this year, with its 3 nm GAAFET node expected to live in 2023. This is at least six months to a year behind TSMC's 3 nm node which is expected to go into production in the second half of 2022. TSMC already has 60 EUV tools for its 3 nm node in its possession, whereas Samsung in comparison is only expected to have 20 at the most and isn't expected to have more than 30 by the end of this year.
 
Maybe the biggest issue for Samsung is that its foundry business isn't making money, as the second quarter profits were only US$268 million, with TSMC raking in over US$13 billion at the same time. Even SMIC and UMC are more profitable than Samsung and it's likely that some of this is down to the fact that third parties are wary about using Samsung's foundries due to a wide range of reasons, least not that Samsung is often a direct competitor. Samsung has considered spinning off its foundry business in the past and this might still come to pass, but it's apparently not something the company is considering now.
 
Samsung has a lot of work ahead of itself to not only stay competitive with TSMC, but also to convince potential customers to choose them over its competitors, even more so now maybe, as Intel is also vying for a slice of the foundry business cake. With TSMC having announced that it'll be investing US$100 billion between 2021 and 2023, in capacity expansion, or roughly twice that of Samsung's sales from its foundry business, it's going to be tough for Samsung to stay competitive without more business. Rumours are that Tesla might be moving from TSMC to Samsung and we also know that Google is working with Samsung on its Tensor SoC. However, these are still fairly small business opportunities and Samsung needs some high-volume customers to be able to keep up with TSMC long term.”
 
My thoughts:  I am surprised that Samsung hasn’t already made their foundry an independent subsidiary business.
