Node progression and manufacturing milestones

Understanding the node progression embedded in the TSMC roadmap helps customers plan product cycles and platform strategies. The company positions itself to advance from the current generation toward increasingly dense and efficient architectures, with three focal areas: process technology, device architecture, and manufacturing efficiency.

3nm and the near-term trajectory

TSMC’s early 3nm implementations have been a centerpiece of the roadmap, delivering improvements in logic density, performance per watt, and transistor leakage control. The 3nm family serves as a platform for high-performance computing and premium mobile devices, enabling significant gains in throughput-per-watt compared with the prior generation. The TSMC roadmap highlights tight integration between lithography, design-technology co-optimizations, and advanced packaging to unlock system-level benefits.

2nm: gate-all-around and nanosheet innovation

Looking beyond 3nm, the roadmap emphasizes a transition to GAAFET-based nanosheet architectures for 2nm and beyond. This shift is critical for continuing density growth while managing short-channel effects and variability. The TSMC roadmap states that 2nm will leverage refined FinFET-to-GAAFET migration paths, with process integration that supports high-performance logic as well as low leakage for mobile and AI workloads. Customers anticipate substantial improvements in performance-per-watt and die area efficiency, enabling more capable accelerators and edge devices.

1nm and longer-term exploration

Beyond 2nm, the roadmap signals ongoing exploration of 1nm-scale devices. While timelines are subject to technical risk, the focus remains on continued material innovations, advanced lithography, and thermal management strategies. The TSMC roadmap envisions a multi-year journey—from research through pilot lines to high-volume manufacturing—where nanosheet-based devices, novel interconnect schemes, and smarter design rules work in concert to sustain the scaling trend.

Technology enablers behind the roadmap

Several key technologies underpin the progress described in the TSMC roadmap. These enablers shape yield, reliability, and manufacturability as nodes become smaller and devices more complex.

Extreme ultraviolet (EUV) lithography

EUV remains a cornerstone for the most advanced nodes. The roadmap relies on continuous refinements in EUV source power, mask technology, and resist performance. These improvements help reduce multi-patterning requirements and improve throughput, which is essential for achieving acceptable production costs at 2nm and beyond.

Nanosheet and GAAFET architectures

Gate-all-around nanosheet devices are central to the 2nm and 1nm generations described in the roadmap. By wrapping the channel with multiple gates, these devices offer better electrostatics, higher drive current, and reduced leakage. For customers, this translates into chips with greater logic density and improved energy efficiency—critical factors for data center accelerators and mobile SoCs alike.

Advanced materials and interconnects

Beyond the transistor itself, the roadmap emphasizes advances in interconnect materials, low-k dielectrics, and strain engineering. Improved diffusion barriers and copper or cobalt interconnect schemes contribute to lower RC delays and better reliability as pitches shrink.

Design enablement and tooling

To translate process advances into usable products, design toolchains and IP libraries must evolve in lockstep with the manufacturing process. The TSMC roadmap incorporates collaboration with EDA partners, IP developers, and foundry customers to ensure design-for-manufacturing (DFM) practices keep pace with process technology.

Packaging and advanced integration

Chip performance increasingly depends on system-level integration, not just raw transistor density. The TSMC roadmap places strong emphasis on packaging innovations that complement process technology.

CoWoS (chip-on-wafer-on-substrate) for high-bandwidth, multi-die integration aimed at AI accelerators and HPC workloads.
InFO (Integrated Fan-Out) for mobile and consumer devices seeking compact, high-density interconnects with lower parasitics.
SoIC and related 3D-stacked configurations to reduce latency and improve energy efficiency in compute-heavy systems.

These packaging advances enable customers to extract more performance from the same silicon area, helping to maximize the impact of the advanced nodes described in the TSMC roadmap. In parallel, process-architecture co-optimization remains essential to avoid bottlenecks in memory bandwidth and inter-die communication.

Global capacity, supply chain resilience, and geography

Delivering on the TSMC roadmap requires not only cutting-edge fabrication facilities but also a resilient, diversified manufacturing footprint. The company maintains a multi-site strategy to balance demand, reduce risk, and support customers across regions.

Arizona expansion: The path toward advanced nodes is supported by investments in the United States, where a modern fabrication ecosystem helps meet demand for logic and AI accelerators.
Singapore and Taiwan operations: Core fabrication hubs continue to drive leading-edge process technology, backed by robust wafer supply and testing capabilities.
Asia-Pacific supply chain partnerships: A broad ecosystem of suppliers, equipment makers, and IP vendors underpins the TSMC roadmap with reliability and scale.

Capacity planning remains sensitive to geopolitical and market dynamics. The roadmap’s emphasis on manufacturing resilience helps customers plan multi-year roadmaps for devices that depend on a stable, predictable supply of advanced silicon.

Implications for customers and the broader market

For device makers, the TSMC roadmap translates into clearer platform strategies. Companies designing AI accelerators, data-center chips, or premium mobile processors can align their architectures with the expected cadence of node progression and packaging options. The roadmap encourages a portfolio approach—leveraging high-performance nodes for compute-centric workloads while adopting more mature processes and specialized technologies for power-sensitive or cost-sensitive products.

Hardware architects can plan for 2nm and 1nm families when targeting long-lived products that demand sustained performance gains.
IC designers gain access to enhanced design libraries and IP that are optimized for GAAFET-based devices and advanced packaging.
System integrators benefit from higher bandwidth and reduced latency through advanced 3D integration, enabling new class of edge and AI-enabled devices.

The TSMC roadmap also shapes supplier dynamics, from EDA tools to memory and substrate suppliers. A predictable progression reduces risk for startups and established players alike, allowing more time for software ecosystems and algorithm optimization to mature alongside silicon progress.

Risks and challenges along the path

No roadmap is without risk. The path to 2nm and 1nm involves technical hurdles, including yield management at ultra-small geometries, thermal challenges in densely packed nanosheet devices, and the need for more reliable interconnect schemes. The reliance on EUV tools raises cadence and cost considerations, as the supply of high-end lithography equipment is finite and requires ongoing collaboration with equipment vendors. The TSMC roadmap also depends on a healthy global ecosystem for materials, equipment, and IP, making geopolitical conditions and supply-chain visibility important factors for execution.

Additionally, market demand must align with manufacturing capacity. While the company plans for diversified growth across markets—mobile, HPC, automotive—the timing of customer programs can shift. The roadmap therefore emphasizes flexibility: maintaining a broad technology portfolio, investing in capacity where needed, and leveraging advanced packaging to extend the life and usefulness of existing nodes.

Conclusion: looking ahead with a pragmatic vision

The TSMC roadmap represents more than a sequence of process nodes; it is a strategic framework that coordinates technology, manufacturing, and ecosystem development. From 3nm to 2nm and beyond, the roadmap is built on a foundation of nanosheet-based architectures, EUV-enabled lithography, and a packaging toolkit designed to maximize system performance. For customers, this means more options to scale workloads, reduce energy consumption, and deliver innovative products at a faster pace. For suppliers and partners, it signals where investments are most likely to pay off and where standards will be defined.

As the semiconductor industry continues to push the boundaries of what is possible, the TSMC roadmap will remain a critical reference point for planning, collaboration, and execution. By balancing ambitious technology goals with manufacturing discipline and supply-chain resilience, TSMC seeks to sustain its leadership position while enabling the next generation of computing, communication, and intelligent systems.
