Samsung Foundry announced a two-year delay for its 1.4nm (SF1.4) chip production, moving mass production from 2027 to 2029. The revised timeline, presented at the 2026 Next-Generation Lithography + Patterning Conference, signals a strategic recalibration toward execution over aggressive node cadence.
Instead of rushing 1.4nm to market, Samsung will spend three years refining its 2nm (SF2) processes to improve yields and production volumes—a move that directly targets the AI accelerator market where volume and cost matter more than cutting-edge geometry. The company is developing multiple 2nm variants: SF2P, SF2X, SF2A, and SF2Z (which features backside power delivery), with the performance-enhanced SF2P+ slated for mass production between 2027 and 2028.
The delay reflects Samsung's long-term supply agreement with Tesla, which runs through 2033 and calls for AI5 and AI6 processors. Securing and retaining major customers requires reliable yields and stable supply chains—lessons Samsung learned the hard way during its troubled 3nm ramp.
The strategy leaves Samsung trailing TSMC, which plans to begin A14 mass production in 2028. But the calculus here is different: TSMC is chasing leading-edge design wins from Apple and AMD; Samsung is targeting the broader AI infrastructure market where 2nm economics can still command premium pricing if the company executes.
For future nodes, Samsung confirmed adoption of High-NA EUV lithography. The company has purchased an ASML Twinscan EXE:5000 system and plans to integrate High-NA starting with its SF1A (1nm-class) node around 2030. That represents Samsung's first public commitment to High-NA, a critical technology bet that will require both capital investment and process redesign.
Samsung also plans to extend 2nm's runway by adopting EUV pellicles for photomasks—a manufacturing discipline change that will require recipe adjustments across multiple process nodes and further justifies the extended 2nm refinement window.
The company's first-quarter 2026 earnings showed momentum in securing HPC design wins for its foundry business and reported active ramp of second-generation 2nm mobile production. Samsung is pursuing large-scale 2nm customer expansion, suggesting the delay reflects confidence that 2nm will remain competitive enough to capture significant revenue before the push to 1nm-class.
