Samsung's Second-Gen 3 nm GAA Process Shows 20% Yields, Missing Production Goals

Samsung's latest semiconductor manufacturing technology is falling short of expectations, as the company struggles to achieve acceptable production rates for its cutting-edge 3 nm chips. The latest rumors indicate that both versions of Samsung's 3 nm Gate-All-Around (GAA) process produce fewer viable chips than anticipated. The initial targets set by the South Korean tech giant were aimed at a 70% yield rate in volume production. However, the first "SF3E-3GAE" iteration of the technology has only managed to achieve between 50-60% viable yield output. More troubling is the performance of the second-generation process, which is reportedly yielding only 20% of usable chips—a figure that falls dramatically short of production goals. The timing is particularly challenging for Samsung as major clients begin to reevaluate their manufacturing partnerships.

Qualcomm has opted to produce its latest Snapdragon 8 Elite processors exclusively through rival TSMC's 3 nm facilities. Even more telling is the exodus of South Korean companies, traditionally loyal to Samsung, who are now turning to TSMC's more reliable manufacturing processes. While Samsung can claim the achievement of bringing 3 nm GAA technology to market before TSMC's competing N3B process, this technical victory rings hollow without the ability to mass-produce chips efficiently. The gap between Samsung's aspirations and manufacturing reality continues to widen. However, Samsung is shifting its focus toward its next technological milestone. Development efforts are reportedly intensifying around a 2 nm manufacturing process, with plans to debut this technology in a new Exynos processor (codenamed 'Ulysses') for the 2027 Galaxy S27 smartphone series
 
The yields must be much worse than stated since the only GAA 3nm chips Samsung has made that I heard of were small cryptomining ASICs.
 
Sounds like they nearly can start producing SF3E-3GAE chips with nearly 60% viability rate output. But, the industry has since moved onto to TSMC's various N3 nodes which are actually in producing chips that shipping.

I'm wondering what the new Samsung fab at Taylor Texas can do if the yield rate is so poor.
 
While Samsung has struggled for some time on Foundry processing, I would be careful about slamming them on 3 GAA yield. Perhaps we should wait until any other company is shipping GAA at higher yield. One company that was supposed to be shipping GAA this quarter cancelled the process to save money. Also new architectures tend to have a lot of Systemic and non-defect yield issues so D0 and the standard yield equations may or may not apply real well. just a thought

We will know who is really doing well on GAA in 2H 2025
