Samsung details upcoming 2nm nodes, talks of future 1.4nm nodes (coming in 2029)

Samsung’s Roadmap: Deep Dive into 2nm and 1.4nm Chip Tech

At the recent Samsung Advanced Foundry Ecosystem (SAFE) Forum, Samsung pulled back the curtain on its ambitious semiconductor manufacturing roadmap. The tech giant isn’t just focused on staying competitive; they are actively reshaping how chips are designed from the ground up.

Building on the momentum of the Exynos 2600—the industry’s first 2nm mobile chip developed on the SF2 node—Samsung is now setting its sights on the next iteration: SF2P. This upcoming node promises a significant performance jump, aiming for a 26% reduction in power consumption and a 15% boost in clock speeds.

The Power of DTCO

So, how are they achieving these numbers? It isn’t just about shrinking transistors. Shin Jong-shin, VP of Design Platform Development at Samsung Foundry, highlights that over half of these efficiency gains come down to DTCO (Design-Technology Co-Optimization). Traditionally, designing the chip architecture and developing the manufacturing process were two separate worlds. By bridging that gap and working on both simultaneously, Samsung is creating chips that are inherently faster, more efficient, and more cost-effective.

Looking further ahead, the company is already planning the SF2P+ node for a 2027-2028 rollout, alongside a specialized SF2X node specifically tailored for high-performance AI hardware.

Solving the SRAM Bottleneck

Beyond the nodes themselves, Samsung is tackling the physical limitations of SRAM. Because SRAM is crucial for CPU and GPU caches, it needs to be fast—but it also consumes a massive amount of space compared to DRAM. While a single-bit DRAM cell uses just one transistor, an SRAM cell requires six, making space optimization a constant engineering headache.

Samsung is pushing boundaries here, partnering with Groq to develop an LLM accelerator that boasts over 500MB of on-die SRAM, even on older 4nm architecture. It’s an impressive feat that signals how much the company is prioritizing memory density alongside processing power.

The Road to 1.4nm

The long-term horizon is arguably the most exciting part. Samsung has confirmed that the 2nm era will eventually give way to 1.4nm technology, with mass production of the SF1.4 node slated for 2029. While the timeline has shifted slightly from original estimates, it serves as a clear indicator of where the semiconductor industry is heading as we approach the end of the decade. With SF1.4+ following shortly after in 2030, Samsung is firmly committed to keeping pace with the rapid evolution of modern computing.
