TSMC Breaks Ground on Third Arizona Fab, Escalating Advanced Chip Manufacturing in the U.S.
TSMC Arizona has officially begun construction on its third semiconductor fabrication facility in Phoenix, signaling the company’s deepening commitment to building a comprehensive and cutting-edge chip manufacturing hub in the United States. This third fab will sit adjacent to TSMC’s first two facilities, which are scheduled to begin production in 2025 and 2026 with 4nm and 3nm process technologies, respectively.

This third fab will sit adjacent to TSMC’s first two facilities, which are scheduled to begin production in 2025 and 2026 with 4nm and 3nm process technologies, respectively.
Although detailed specifications for the third fab remain undisclosed, industry insiders anticipate it will deploy TSMC’s upcoming 2nm process node or more advanced technologies, with production expected to commence later this decade. This move aligns with the surging global demand for high-performance, low-power chips driven by artificial intelligence (AI) and high-performance computing (HPC).
Intel: Reviving Foundry Leadership with 18A and Beyond
Intel is pursuing an aggressive roadmap under its IDM 2.0 strategy to reclaim leadership in semiconductor process technology. The company’s 18A (1.8nm) node, now in the risk production phase, introduces RibbonFET transistor architecture and PowerVia backside power delivery, promising significant performance and power efficiency gains. Production is expected to ramp up in Oregon, with Arizona fabs supporting manufacturing scale.
Intel is also developing enhanced versions of 18A—namely 18A-P and 18A-PT—and has initiated early-stage production. These technologies integrate advanced 3D packaging like EMIB and Foveros to meet the evolving needs of AI and HPC chips.
Looking forward, Intel is progressing toward its 14A node, which promises up to 20% power efficiency gains and a 1.3x increase in transistor density. This node could enter risk production by 2027.
To diversify its offerings, Intel is also expanding its mature node foundry services. The company recently partnered with UMC to manufacture 12nm chips at its Arizona facilities, while simultaneously producing 16nm-class chips for MediaTek at its Ireland site. Intel aims to become the world’s second-largest foundry by 2030, targeting CPU, GPU, AI accelerators, and advanced packaging services.
Samsung: Betting Big on GAA and 2nm Technologies
Samsung continues to strengthen its position in the foundry market with a strong emphasis on Gate-All-Around (GAA) transistor technology and the upcoming 2nm node. Although its initial 3nm rollout faced yield challenges, Samsung reports steady improvements in performance and manufacturability.
Samsung plans to trial-produce its 2nm Exynos 2600 chip in May 2025, with potential deployment in its Galaxy S26 smartphone series. The company has also announced the SF2Z and SF4U nodes—enhanced versions of its 2nm and 4nm processes—with SF4U scheduled for mass production in 2025 and SF2Z by 2027.
Meanwhile, Samsung’s Texas fab in Taylor is being prepared to produce 3nm and 2nm chips, with AI chipmaker Groq confirmed as its first customer. Samsung is also actively seeking partnerships with AI chip firms to secure more advanced chip orders.
TSMC: Reinforcing Process Leadership with 2nm and Beyond
TSMC remains the global leader in advanced semiconductor manufacturing. Its N2 (2nm) process is set to enter mass production in late 2025, featuring nanosheet transistor architecture that offers enhanced performance and efficiency. TSMC is also developing the A16 process node, which will incorporate its proprietary SuperPowerRail backside power delivery.
The company’s 3nm (N3) family, including N3X and N3AE, is already in high-volume production at Fab 18. In 2024, 7nm and below nodes accounted for 69% of TSMC’s wafer revenue—up from 58% the previous year—highlighting continued strong demand for cutting-edge process nodes.
With AI and HPC projected to make up 45% of the global semiconductor market by 2030, TSMC is positioning itself to meet soaring demand. The company is expanding its CoWoS advanced packaging capacity and adjusting pricing to reflect its technological leadership and rising market demand.
Conclusion: A Fierce Three-Way Battle for the Future of Semiconductor Technology
Intel, Samsung, and TSMC are locked in a high-stakes race to dominate next-generation process technologies. Intel is making a bold push through its IDM 2.0 strategy and 18A roadmap. Samsung is leveraging its early GAA leadership and 2nm progress to close the gap. Meanwhile, TSMC continues to maintain its lead with a proven track record of stability, scale, and customer trust.
As the world moves deeper into the AI and HPC era, the battle for supremacy at the nanometer scale will shape the future of global tech. The foundry that leads in 2nm and beyond will hold a decisive edge in the coming decades.
