Major Milestones in Advanced 12-Inch Wafer Fabs: TSMC, Intel, and Samsung Lead the Way !
The semiconductor industry continues to advance, with significant updates from leading players. On November 26, TSMC held an equipment installation ceremony at its first 12-inch wafer fab in Kaohsiung, Taiwan, marking a shift from construction to production for its 2nm process. Meanwhile, Intel announced a $7.86 billion subsidy agreement with the U.S. Department of Commerce to support its 12-inch wafer fabs and advanced packaging projects across Arizona, New Mexico, Ohio, and Oregon. The Ohio facility will focus on cutting-edge process technologies.

Global Push for Advanced Processes and Packaging
Driven by surging demand for high-performance computing, advanced storage, and industrial manufacturing chips, the global race to develop advanced processes and packaging technologies is accelerating. Industry giants TSMC, Samsung, and Intel are leading this charge, with roadmaps pointing to transistor scaling to the 18/16/14 Angstrom level and transitioning from nanosheet and fork-sheet field-effect transistors (FETs) to complementary FETs (CFETs). Each company is also developing unique enabling and extension technologies, showcasing distinct strategies for competitive differentiation.
TSMC: Expanding Advanced Nodes with Confidence
TSMC's Kaohsiung fab signifies its first 12-inch wafer plant in the region and will begin production six months ahead of its original schedule, targeting mass production by 2025. This facility, alongside Hsinchu’s Baoshan fabs, forms a critical part of TSMC’s advanced 2nm ecosystem. Major clients like Apple and AMD are expected to be among the first to adopt the technology.
Initially planned for mature processes, the Kaohsiung fab pivoted to the 2nm node as AI-driven demand for high-performance computing and storage surged. TSMC’s 2nm process is already generating more inquiries than its 3nm counterpart, with production capacity set to exceed expectations.
In addition to Kaohsiung, TSMC has advanced nodes operational or in progress in Arizona and other global locations. The company plans to begin mass production of its N2 process by late 2025 and roll out its A16 (1.6nm) node in 2026. This process will incorporate backside power delivery to enhance logic density and performance, targeting applications in high-performance computing.
Samsung: Progress in Advanced Processes and Packaging
Despite challenges with yields and delays in process advancements, Samsung remains a key player in semiconductor manufacturing. Its 3nm technology, which introduced Gate-All-Around (GAA) transistors, is undergoing optimization, with yield improvements anticipated for both the 3GAE and 3GAP variants.
Samsung is investing heavily in its facilities, including the Hwaseong and Pyeongtaek fabs in South Korea, which are being outfitted for 2nm and 1.4nm production lines. The company also revealed two new nodes—SF2Z and SF4U. SF2Z, a 2nm variant incorporating backside power delivery networks, is set for mass production in 2027. SF4U, a 4nm variation, is planned for 2025.
Samsung’s roadmap also emphasizes advanced packaging, such as 3.5D and 5.5D concepts that combine 3D-IC and 2.5D packaging for improved thermal management and performance. These innovations are expected to solidify Samsung’s position in the next generation of advanced packaging technologies.
Intel: A Potential Comeback in Advanced Nodes
Intel has faced mounting challenges in process technology leadership, but recent developments suggest a potential rebound. On November 26, Intel secured a $7.86 billion subsidy from the U.S. government to bolster its advanced wafer fabs and packaging projects across multiple states.
Intel has also made strides in its process technology roadmap, transitioning to Intel 4 (7nm) and Intel 3 nodes. Intel 3, primarily targeting data centers, is comparable to industry-standard 3nm processes and offers a 17% performance-per-watt improvement over Intel 4. Intel’s upcoming 20A (2nm) and 18A (1.8nm) nodes will incorporate RibbonFET transistors and PowerVia backside power delivery for enhanced performance.
Key customers, including AWS and Microsoft, have already committed to Intel’s advanced nodes, providing confidence in its foundry services and opening opportunities for future collaborations with tech giants like Apple and Qualcomm.
Advanced Nodes Shaping the Foundry Landscape
Advanced process technologies, defined as nodes below 28nm, are driving growth in high-performance computing and AI applications. According to TrendForce, the foundry market is expected to recover by 2025, with a 20% growth rate, driven by demand for advanced nodes (5nm and below) and flagship smartphone chips.
TSMC leads this segment, with 7nm and below nodes accounting for 69% of its wafer revenue. Meanwhile, Samsung and Intel are making strategic investments to compete in advanced nodes and packaging. By 2027, the foundry landscape will hinge on Intel’s success with its 18A process and Samsung’s progress in achieving higher yields and scaling production.
As AI and HPC applications continue to dominate semiconductor demand, the competition among TSMC, Samsung, and Intel to push process technologies to 1.4nm and beyond will shape the future of the foundry industry.
