The company's batch formation process is designed for mass production, contrasting with IBM's costly method. The prototype was presented at the 2026 VLSI Symposium. Samsung's foundry roadmap shows SF2P yield improvement and resumed SF1.4 development, with CFET as the next step.","whyItMatters":"Samsung's CFET prototype offers a mass-production-oriented alternative to IBM's expensive CFET method, signaling a focus on practical scaling for future nodes.","webCardHtml":"\u003cp\u003eSamsung presented its third CFET prototype at the 2026 VLSI Symposium, this time with a 42nm gate pitch and triple stacked nanosheet channels.

Samsung\u0026#39;s foundry division has been working to recover from yield issues with its SF3 and SF2 nodes. After freezing SF1.4 development in early 2025 to improve SF2 yield, the company resumed SF1.4 work in June 2026, targeting mass production in 2029. CFET is positioned as the next-generation architecture beyond that.\u003c/p\u003e","blueskyPost":"Samsung showed its third CFET prototype at VLSI 2026, using a batch process aimed at mass production.
