Samsung Pushes 1.4nm Chip Production to 2029, Eyes 1nm with High‑NA EUV

High‑NA EUV: The Engine Driving Sub‑10nm Advancement

Samsung Foundry announced on August 12 that its 1.4 nm process will now roll out in 2029, extending the life of its SF2 platform. The shift places the company’s most advanced node among the longest‑running in its history, while high‑numerical‑aperture extreme ultraviolet (high‑NA EUV) lithography is slated to unlock true 1 nm and smaller geometries from 2030 onward.

The delay reflects a strategic pause to integrate high‑NA EUV tools, which promise finer patterning and better yield at sub‑10 nm scales. Samsung’s revised roadmap also aligns with industry‑wide supply chain constraints and the steep cost of next‑generation equipment. By postponing the 1.4 nm launch, the company hopes to perfect the new lithography platform before committing silicon wafers to mass production.

High‑NA EUV machines use a larger numerical aperture to focus light more tightly than current EUV tools, enabling critical dimensions below 10 nm with fewer patterning steps. Samsung has invested heavily in this technology, partnering with equipment makers to secure early access. Executives say the new tools will reduce line‑edge roughness and improve transistor performance, essential for keeping Moore’s Law alive. Early test chips have shown a 15 % power reduction and a 10 % speed boost compared with the previous generation, underscoring the potential of the approach.

Will Samsung’s 2029 Timeline Hand an Advantage to Competitors?

The company’s roadmap now places the high‑NA EUV‑enabled 1 nm node in the early 2030s, a timeline that matches rival roadmaps from TSMC and Intel. Samsung expects the technology to open doors for advanced AI accelerators, high‑performance computing, and next‑generation mobile SoCs. By aligning its production schedule with the arrival of high‑NA EUV, Samsung aims to deliver chips that meet the growing demand for compute‑intensive workloads while maintaining competitive pricing.

Industry analysts caution that the five‑year gap between 1.4 nm and 1 nm could allow rivals to capture market share in premium segments. TSMC’s roadmap suggests a 3‑nm node in 2027 and a 2‑nm in 2029, potentially narrowing Samsung’s lead in high‑performance segments. However, Samsung’s focus on high‑NA EUV may offset this risk by delivering superior performance per watt once the 1 nm node arrives. The company’s ability to scale production efficiently will be critical; any bottlenecks in high‑NA EUV deployment could erode its competitive edge.

Overall, Samsung’s revised schedule signals a cautious but forward‑looking strategy. By deferring the 1.4 nm launch, the firm positions itself to harness high‑NA EUV’s full benefits, aiming for a leap in chip density and power efficiency. The move may reshape the competitive landscape, but success hinges on flawless integration of the new lithography tools and the ability to meet customer demand for next‑generation silicon.

Frequently Asked Questions

When will Samsung’s 1.4 nm process become commercially available? The company plans to begin volume production of the 1.4 nm node in 2029, following a ramp‑up period that starts later that year.

What is high‑NA EUV and why is it important? High‑NA EUV is a next‑generation lithography technology that uses a larger numerical aperture to focus light more precisely, enabling smaller feature sizes and higher yields at sub‑10 nm nodes.

How might Samsung’s delay affect its market position? The postponement could give rivals a short‑term advantage in high‑performance segments, but Samsung’s investment in high‑NA EUV may deliver a stronger long‑term product offering that offsets any temporary loss.
