TL;DR: Samsung plans to start mass production of its 1.4nm process in 2029, followed by an improved 1.4nm+ node in 2030. The delay from the original 2027 target is due to focusing on enhancing yields for its 2nm process, which will begin production in 2027 and 2028.

Although it's missing its initial 2027 target, a new roadmap delivered at Samsung Foundry's SAFE Forum 2026 event in South Korea says the company is set to begin mass production of its cutting-edge 1.4nm process (SF 1.4) in 2029. Shin Jong-shin, an Executive Vice President at Samsung Foundry, also confirmed that the company has begun developing its second-generation 1.4nm process, SF1.4+, which will go into mass production the following year, 2030.

"We will accelerate collaboration with global AI and high-performance computing (HPC) customers and strengthen our role as a platform for South Korea's domestic system semiconductor industry," Shin Jong-shin said. "Development is progressing smoothly with a target for mass production in 2029, and an enhanced node, SF1.4 Plus, featuring improved yield and performance, is scheduled for introduction in 2030."

An additional report from last week also confirms the 2029 target, noting that Samsung is liaising with international partners such as Applied Materials and Lam Research to ensure equipment is ready on time.

Although delayed, Samsung notes that the main reason the 1.4nm process chips missed the original 2027 target is the company's focus on improving yields for its 2nm process. And with that, Samsung's second-generation SF2P 2nm process has delivered up to 15% higher clock speeds and 26% better efficiency, with the company also developing third- and fourth-generation 2nm process technologies, SF2P+ and SF2X, which are being built for high-performance chips and devices. Mass production for these is expected to kick off in 2027 and 2028, respectively.

Question 01

Will Samsung's SF1.4 process be targeted mainly at AI/HPC chips or also for mobile SoCs and consumer products?

The primary article indicates Samsung will accelerate collaboration with global AI and high-performance computing (HPC) customers and showed an NVIDIA Grok 3 LPU wafer at the SAFE Forum, suggesting a strong AI/HPC focus for SF1.4. The article does not state whether SF1.4 will also target mobile SoCs or broader consumer products.

Question 02

Given Samsung's collaboration with Applied Materials and Lam Research, are there expected equipment-related constraints that could further delay SF1.4 mass production?

Question 03

How might the improved yields on Samsung's SF2P 2nm process affect supply and pricing for chips that might otherwise shift to SF1.4?

Improved yields on Samsung's second-generation SF2P 2nm process could reduce pressure to shift chips to the later SF1.4 node by making 2nm more performant and efficient, meaning some designs that might have moved to SF1.4 could remain on SF2P. The article notes SF2P delivered up to 15% higher clock speeds and 26% better efficiency, implying better supply and potentially more stable pricing for 2nm chips versus an earlier shift to SF1.4.

Question 04

If Samsung partners with NVIDIA on next-generation chips, would those NVIDIA wafers likely be manufactured on SF1.4 in 2029 or on the existing 4nm/2nm processes mentioned?

As for what the next-gen 1.4nm process will be used for remains to be seen, but one of the highlights at the SAFE Forum 2026 event was Samsung displaying a Grok 3 Language Processing Unit (LPU) wafer signed by NVIDIA CEO Jensen Huang. Samsung, which is developing an AI inference chip using its 4nm process, also hinted at a possible next-generation collaboration with NVIDIA.
