Samsung Foundry has reached a critical manufacturing milestone that could reshape the global chip supply chain. The company's 4-nanometer chip manufacturing process has surpassed 80 percent yield, a threshold that signals the process has matured enough to attract major new customers. In semiconductor manufacturing, hitting 80 percent yield is considered a sign that a production process is stable, reliable, and ready for large-scale commercial orders.

What Does an 80% Yield Actually Mean for Chip Manufacturing?

When chip manufacturers produce semiconductors, not every chip that comes off the production line works perfectly. Yield refers to the percentage of usable chips produced from a batch of wafers. At 80 percent yield, Samsung is now producing four working chips for every five it manufactures, which is considered industry-standard for a mature process. This matters because higher yields mean lower costs per chip, making Samsung more competitive against rivals like Taiwan Semiconductor Manufacturing Company (TSMC), which currently dominates the contract chip manufacturing market.

Samsung may be the world's second-largest contract chip maker, but it significantly lags behind TSMC in foundry market share. However, this yield milestone could change that dynamic. As Samsung demonstrates it can reliably produce chips at scale, major technology companies are already taking notice and placing orders.

Which Companies Are Already Using Samsung's 4nm Process?

Several major firms have already begun manufacturing chips using Samsung Foundry's 4nm process, signaling confidence in the company's capabilities. The customer list spans artificial intelligence (AI) companies, semiconductor designers, and tech giants:

• Groq (Nvidia subsidiary): The AI chip company, recently acquired by Nvidia, has reportedly ordered Samsung to manufacture its Language Processing Units (LPUs), which are specialized processors designed for AI inference tasks.
• Baidu: The Chinese search and AI company is having chips manufactured using Samsung's 4nm process for its own AI and cloud services.
• IBM: The computing giant is leveraging Samsung's foundry services for chip production.
• Ambarella and Faraday: These semiconductor design companies are also utilizing Samsung's 4nm capabilities.
• South Korean AI firms: FuriosaAI and Rebellion, both based in South Korea, are using the process for their AI accelerator chips.

Samsung's own memory division is also using Samsung Foundry's 4nm process for the base die of its sixth-generation high-bandwidth memory (HBM4) chips, which launched earlier this year. HBM chips are critical components in AI systems, providing the fast memory that AI processors need to handle large language models and other computationally intensive tasks.

How Samsung's Foundry Success Could Reshape the Chip Industry

Samsung's yield milestone arrives at a pivotal moment for the semiconductor industry. The global demand for advanced chips has surged due to the AI boom, creating opportunities for manufacturers who can reliably produce at scale. TSMC has long dominated this space, but Samsung's improving capabilities could force competition that benefits customers through more choices and potentially lower prices.

The company's non-memory chip business, which includes Samsung Foundry and System LSI (a division that designs chips for Samsung's own products), is expected to return to profitability in the second half of 2026. This financial recovery would mark a significant turnaround for a division that has struggled in recent years, suggesting that Samsung's manufacturing improvements are translating into real business gains.

The 80 percent yield achievement also demonstrates that Samsung's investment in advanced manufacturing technology is paying off. Reaching this threshold typically requires years of process refinement, equipment optimization, and engineering expertise. For customers evaluating foundry partners, it signals that Samsung can now deliver the reliability and consistency they need for high-volume production.

What This Means for the Broader Tech Ecosystem

Samsung's progress in 4nm manufacturing has ripple effects across the technology industry. Companies developing AI chips, data center processors, and consumer electronics now have a credible alternative to TSMC for advanced chip production. This competition is healthy for the industry because it reduces dependence on a single manufacturer and creates redundancy in the global chip supply chain, which remains vulnerable to disruptions.

For consumers, Samsung's foundry success could eventually mean more diverse chip options in devices, potentially faster innovation cycles as companies have more manufacturing partners to choose from, and greater supply chain stability. The company's ability to produce high-quality chips at scale also supports the broader AI infrastructure buildout that powers everything from cloud services to consumer AI features in smartphones and computers.
