Tsmc Achieves Breakthrough In Chip Manufacturing With Pioneering 2Nm-Class Technology

Taiwan Semiconductor Manufacturing Company (TSMC) has quietly begun volume production of its next-generation 2nm-class chips, marking the first time the company has adopted gate-all-around (GAA) nanosheet transistors in its fabrication process. This technological breakthrough is expected to deliver impressive performance gains and power efficiency improvements, further solidifying TSMC’s position as a leader in the semiconductor industry.

The 2nm (N2) technology commenced volume production in the fourth quarter of 2025, exceeding the company’s previously announced timeline. According to TSMC’s official website, this achievement is a testament to the company’s commitment to innovation and its ability to deliver cutting-edge technologies on schedule.

The N2 process node boasts several significant improvements over its predecessor. A 10% to 15% performance gain at the same power consumption, a 25% to 30% reduction in power consumption at the same performance level, and a 15% increase in transistor density compared to the N3E process for mixed designs that incorporate logic, analog, and SRAM are just a few of the key benefits. For logic-only designs, TSMC expects a 20% higher transistor density than N3E.

One of the key features of the N2 process is its adoption of gate-all-around (GAA) nanosheet transistors, which provide improved electrostatic control, reduced leakage, and enhanced performance without sacrificing power efficiency. This innovative design enables TSMC to create smaller transistors that are more efficient and powerful than ever before.

In addition to the GAA nanosheet transistors, N2 also introduces super-high-performance metal-insulator-metal (SHPMIM) capacitors to its power delivery network. These advanced capacitors offer significantly higher capacitance density than traditional designs, reducing sheet resistance (Rs) and via resistance (Rc) by 50%. This improvement enables more efficient power stability, performance, and overall energy efficiency.

The N2 process node is expected to have a significant impact on the semiconductor industry, particularly in the fields of smartphone manufacturing and high-performance computing (HPC). TSMC’s CEO, C.C. Wei, has stated that the company expects a faster ramp-up in 2026, driven by demand from both smartphone and HPC AI applications.

TSMC began mass-producing N2-class chips at its Fab 22 facility near Kaohsiung, Taiwan, rather than the previously expected Fab 20, which is located adjacent to the company’s new global R&D center. This decision highlights the strong interest in the N2 process from a variety of TSMC partners and underscores the company’s commitment to meeting demand for this advanced technology.

While ramping up production at two N2-capable fabs simultaneously may pose some challenges, it is also seen as an opportunity for TSMC to capitalize on the growing demand for its products. The company plans to use both fabs to produce chips on N2P, a performance-enhanced version of N2, and A16, a variant of N2P with advanced Super Power Rail (SPR) backside power delivery designed specifically for complex AI and HPC processors.

The adoption of gate-all-around nanosheet transistors and super-high-performance metal-insulator-metal capacitors in the N2 process node is expected to revolutionize the semiconductor industry, driving innovation and growth across various sectors. With its commitment to delivering cutting-edge technologies, TSMC remains at the forefront of chip technology advancements.

As TSMC continues to push the boundaries of what is possible in chip technology, it’s clear that the company has demonstrated its ability to deliver groundbreaking performance gains and power efficiency improvements, setting a new standard for the industry. With its N2 process node, TSMC is poised to further solidify its position as a leader in the semiconductor industry.
