Samsung Electronics' Gamble: 'Yield Improvement'... Seeking to Recover Market Share

- Exynos 2600 confirmed for mass production in November of this year
- Will the foundry that has been in deficit revive 2nm?
- Will the Galaxy S26 be equipped as a springboard for attracting major customers?
- TSMC's excessive price hikes... Opportunity for Samsung

The mass production schedule for Samsung Electronics' Exynos 2600, the first to use the 2nm (1㎚=1 billionth of a meter) process, has been confirmed for November. This is only four months after Han Jin-man, head of the Foundry Business Division (President), took office. Immediately after taking office, President Han ordered yield improvement through an internal message, and it is evaluated that the results are being achieved.

According to the semiconductor industry on the 10th, after taking over the foundry division, President Han reviewed the operational status of the existing 2nm process dedicated organization and the production line operation method. In particular, he revised the sales strategy to improve technological competitiveness. While he had previously focused on North American big tech, President Han actively expanded design house partners in various markets such as China, India, and Europe. The strategy is to increase orders for mature processes, lower the fixed costs required to operate the foundry plant, and secure price competitiveness in advanced processes.

Samsung Electronics also applies the 'Gate All Around (GAA)' technology in the 2nm process. It is a technology that is more advanced than the existing FinFET, with a structure that surrounds the transistor through which current flows on all four sides. It has the advantage of increasing chip performance and reducing power consumption, making it advantageous for high-performance semiconductors. Previously, it succeeded in mass producing 3nm using GAA technology for the first time in the world, but the low yield led to poor performance.

As Samsung Electronics has set the mass production date for the Exynos 2600 for November, attention is focused on whether it will create a rebound momentum in its foundry business. If the Exynos 2600 is installed in the Galaxy S26, which is scheduled to be released in the first quarter of next year, without a hitch, it is expected to serve as an example of demonstrating 2nm technology and supply capabilities. The industry believes that proving the stabilization of the 2nm process will help Samsung Electronics attract external customers.

An industry insider said, "The 2nm yield currently under development at Samsung Foundry is much better than previously known," and "more positive than the 3nm process." The 2nm yield was only 20-30% at the beginning of this year, but it was recently reported to have exceeded 40% in the wafer testing stage at a post-processing company.

Samsung Electronics is rapidly increasing its 2nm yield, but it still lags behind industry leader TSMC. TSMC has secured an initial 2nm yield of up to 60%. Considering that mass production usually starts at a yield of 70-80%, stabilizing the yield by the second half of the year is expected to be an important task.

Samsung Foundry failed to overcome yield issues, handing over the leading edge process to TSMC, which became the starting point of the market share gap. According to TrendForce, the market share in the fourth quarter of 2023 widened from TSMC 61.2% and Samsung Electronics 11.3% to TSMC 67.1% and Samsung Electronics 8.1% in the fourth quarter of last year. Samsung's market share fell to single digits for the first time, and the gap with TSMC is 60 percentage points.

Since President Han Jin-man took office in November of last year, the foundry division has been focusing on improving its structure with two tasks: “enhancing technology” and “securing customers.” Some are suggesting that the foundry division should be withdrawn or spun off, but Samsung Electronics is determined to continue investing. This is because if it regains its technological competitiveness, it will be able to establish itself as the only company that can provide “integrated solutions” for design, development, and production.

It is true that Samsung Electronics is lagging behind in terms of securing major customers. However, TSMC's repeated price increases could act as a new opportunity factor. Taiwan's Industry and Technology Times reported early last month that "TSMC is considering raising the price of its advanced processes by more than 15% this year." This is an upward adjustment from the previously known 5-10%, and it is known that this policy has already been conveyed to some customers.

Global fabless companies such as Nvidia, Apple, Qualcomm, and AMD are requesting production from TSMC, but there are constant foreign media reports that Apple and AMD are reviewing Samsung Electronics' 2nm process due to excessive price increases every year. An industry insider said, "Foundries are conducted under long-term contracts that look at the volume for three years in the long term," and "If they prove their 2nm technology, their market share will recover to double digits."

I have heard this is as well, Samsung 2nm yield is improving. I finally found a Samsung 2nm design start. Progress! It would be nice to have three yielding options for 2nm. I am also told that Samsung 2nm has a density lead over TSMC N2 and Intel 18A. Progress!
 
I found this on Twitter for the 40% yield

Yes, I was told Samsung 2nm yield was half of TSMC yield so that checks. Last year Samsung 2nm was single digits. The same happened with Samsung 5/4nm. In fact, there was a big scandal about over reporting yield inside of Samsung.

Samsung's management consulting will focus on former and current executives of DS division ... Did they fabricate yields in a semiconductor foundry?
  • Samsung Electronics is reportedly planning to expand its investigation into the whereabouts of funds executed for securing yields, following a fabricated report on the yield of Samsung Semiconductor Foundry.

    According to the Infostock Daily report on the 21st, the recent management consulting of Samsung Electronics' DS division is looking at the yield rate in 5 nanos processes, following 3 nanos and 4 nanos.

    “Since the delivered quantities are struggling to meet the recent foundry order volume, we have doubts about the yield of the non-memory process, which has been known to be achieved.” said an official who is familiar with the internal situation at Samsung Electronics.

    The official added, "The management consulting investigates the claims on the yield of a semiconductor foundry by former and current DS division executives. The consulting will determine whether the claims are false".


    Samsung Electronics' management consulting is putting more weight on the possibility that the yield is false. The consulting will investigate whether the investment for the yield of the most advanced semiconductor processes was properly executed.

    Cho Ho-jin, CEO of Tachyon World, said, "Samsung Electronics will utilize this investigation as an opportunity to strengthen the group while looking into financials of DS division and legitimacy of the yield in the semiconductor processes".

    "The issue of Samsung Electronics' management means that the company is in the fierce competition with high uncertainty while TSMC is also struggling to secure the yields in 3-nano or 4-nano semiconductor fabrication process." said Choi Yang-oh, an advisor at Hyundai Research Institute. "Investors of Samsung Electronics need to pay close attention to the result of management consulting."

    "The management consulting is performed regularly. The detailed schedule, contents, or results of the consulting cannot be shared at this time." Samsung Electronics said.

Samsung 5/4 had a uncompetitive PPA vs N5/N4 Snapdragon 8 gen 1(Samsung) and 1+ (TSMC) around 11% difference in performance
