Samsung’s 2nm GAA Technology: Analysts Predict Improved Yield as Mass Production Launches in 10 Months

Samsung’s journey to enhance the yields of its groundbreaking 3nm Gate-All-Around (GAA) process has been filled with numerous challenges, casting doubt on its ability to transition smoothly into mass production of 2nm GAA wafers. Interestingly, the company has demonstrated resilience, defying expectations amid adversity.

Recent analyses highlight a marked improvement in Samsung’s yield for its cutting-edge nodes, noting that the advancements made surpass the limitations that plagued its 3nm technology. Nonetheless, the company must continue to strive for excellence, as the clock is ticking.

Current Yield Status of Samsung’s 2nm GAA Process

In prior reports, it was revealed that Samsung’s initial yields during the trial stage for its next-generation Exynos SoC stood at a modest 30 percent for the 2nm GAA process. In comparison, TSMC—Samsung’s primary competitor—achieved a notable 60 percent yield in its own trial production, widening the technological gap between the two industry giants. However, Samsung’s performance during test production of the upcoming Exynos 2600 demonstrates significant progress, with yields reaching 30 percent.

While there’s considerable progress, Samsung still has substantial work to undertake before it can proudly present this advanced technology to prospective customers and reclaim its lost market share. With mounting pressure, the timeline is critical; reports indicate that Samsung has approximately 10 months left to initiate actual production of 2nm GAA wafers. Analysts are optimistic, recognizing that if current trends continue, Samsung may generate sufficient yields to attract potential clients.

Additionally, by the fourth quarter of last year, Samsung’s foundry division had commenced the installation of equipment necessary to establish a 2nm GAA production line within the S3 facility in Hwaseong. The strategy involves adapting the existing 3nm GAA line—which produces about 15, 000 sheets per month using 12-inch wafers—into a dedicated 2nm production line. Test production could occur as early as this year, and updates will be provided to keep readers informed of Samsung’s progress or setbacks.
