Samsung Foundry Utilization Rebounds
Samsung's foundry business has rebounded, with its capacity utilization rate climbing above 80% in the first quarter of 2026. This recovery positions Samsung as a more viable alternative to TSMC for advanced node foundry services. The increased utilization comes amid ongoing policy uncertainty in the US and China, which affects global semiconductor supply chains.
- The recovery is significantly driven by Samsung's new 2nm process, which is being used to mass-produce the Exynos 2600 chip for the upcoming Galaxy S26 series. Manufacturing yields for this 2nm Gate-All-Around (GAA) process have reportedly reached 50%, a crucial milestone for commercial viability. - This rebound is concurrent with Samsung's major expansion in the U.S., where it is investing over $40 billion to create a semiconductor hub in Taylor, Texas. The project, supported by up to $6.4 billion in U.S. CHIPS and Science Act funding, will produce 4nm and 2nm chips and is slated to begin operations in 2026. - Beyond its internal Exynos orders, Samsung has secured long-term contracts for AI chips with major automotive and tech companies. Notable new customers include Tesla and the U.S. AI firm Tsavorite Scalable Intelligence, which placed an order exceeding $100 million for an Omni-Processing Unit (OPU) on Samsung's 4nm node. - Improved manufacturing yields on more mature nodes, particularly the 4nm process, have also been a key factor in the turnaround. Reports indicate 4nm yields have stabilized in the 60-70% range, making the process more attractive to external customers after previous struggles. - Samsung was the first foundry to introduce Gate-All-Around (GAA) transistor architecture at its 3nm node, moving away from the FinFET structure that TSMC still uses for 3nm. While early 3nm GAA yields were poor, the experience is foundational for its more stable 2nm GAA process. - While the utilization rebound is significant, Samsung's foundry market share remains a distant second, hovering around 7-9%. This is compared to TSMC's commanding market share of approximately 70%. - Samsung has a roadmap extending to a 1.4nm process, though mass production has been pushed to 2029. This timeline places it about a year behind TSMC's target for its own 1.4nm-class node, which is expected in 2028. [cite: 21,
