TSMC Symposium Highlights

TSMC roadmap

This year marks the 30th anniversary of TSMC’s North America Technology Symposium, and more than 2,000 attended the event, growing from less than 100 attendees 30 years ago. The North America Technology Symposium in Santa Clara, California kicks off TSMC Technology Symposiums around the world in the coming months. The symposium also featured an “Innovation Zone,” designed to highlight the technology achievements of our emerging start-up customers.

We are entering an AI-empowered world, where artificial intelligence not only runs in data centers, but PCs, mobile devices, automobiles, and even the Internet of Things,”

Dr. C.C. Wei, TMSC CEO

New Technologies introduced in the TSMC Symposium

1. TSMC introduced its A16™ Technology in Symposium

TSMC A16 Comparison to N2P

The next milestone in its semiconductor roadmap, the A16 (1.6nm) builds on the success of N3E technology currently in production and with N2 (2nm) slated for release in late 2025, A16 combines TSMC’s innovative Super Power Rail architecture with nanosheet transistors. This combination is set to enhance logic density and performance by allocating front-side routing resources specifically to signals.

A16 is particularly suited for High Performance Computing (HPC) products, boasting intricate signal routes and dense power delivery networks. Compared to TSMC’s N2P process, A16 promises significant improvements: an 8-10% speed enhancement at the same positive power supply voltage (Vdd), a 15-20% reduction in power consumption at the same speed, and up to a 1.10X increase in chip density, tailored especially for data center products.

2. TSMC Nanoflex for Nanosheet transistors

TSMC also unveiled its NanoFlex™ Innovation for Nanosheet Transistors, accompanying the upcoming N2 technology. This new N2 process is scheduled for 2025 and will have a capability like N3’s FinFlex technology, called NanoFlex. This will allow the mixing of short cells and tall cells in the same block to get better PPA by mixing in the best ratio of cells for any given design. Figure below shows the advantages of a mixed height design over a short cell only implementation.

This flexibility allows customers to fine-tune their designs, achieving optimal power, performance, and area tradeoffs for their specific applications.

3. N4C technology at TSMC Symposium

Furthermore, TSMC introduced N4C Technology, an extension of its N4P technology aimed at a broader range of applications.

N4C promises up to an 8.5% reduction in die cost with minimal adoption effort, scheduled for volume production in 2025. It offers area-efficient foundation IP and design rules fully compatible with N4P, delivering better yield through die size reduction. This provides a cost-effective option for migrating value-tier products to TSMC’s next advanced technology node.

N4 is tsmc’s 4nm technology. After N4, TSMC released N4P technology which improved N4’s performance by 6%. And now we have N4C.

4. CoWoS, SoIC and System on Wafer (TSMC-SoW) in TSMC Symposium

In addition to these advancements, TSMC showcased its commitment to innovation in advanced packaging technologies such as CoWoS®, SoIC, and System-on-Wafer (TSMC-SoW™). CoWoS has played a pivotal role in the AI revolution by enabling customers to densely pack processor cores and high-bandwidth memory (HBM) stacks on a single interposer.

TSMC-SoW introduces a novel approach, enabling a large array of dies on a 300mm wafer, offering increased compute power while occupying significantly less data center space and enhancing performance per watt by several orders of magnitude.

5. Silicon Photonics integration at TSMC Symposium

TSMC also highlighted its efforts in Silicon Photonics Integration, introducing COUPE™ technology to support the surging demand for data transmission in the AI era. COUPE utilizes SoIC-X chip stacking technology to stack electrical and photonic dies, offering superior energy efficiency and reduced impedance at the die-to-die interface. TSMC plans to qualify COUPE for small form factor pluggables in 2025, followed by integration into CoWoS packaging as co-packaged optics (CPO) in 2026.
