TSMC's 2nm chip will be mass-produced in the second half of the year, using GAA technology

TSMC revealed at the 2025 North American Technology Symposium that the company is expected to begin mass production of N2 (2nm level) chips in the second half of this year, which is its first production technology relying on ring gate (GAA) nanosheet transistors.

This new node will support numerous products that will be launched next year, including AMD's next-generation EPYC "Venice" CPU for data centers, as well as various client oriented processors, such as Apple's 2025 chips for smartphones, tablets, and PCs. Thanks to GAAFET (Surrounding Gate Transistor) and enhanced power output, the new 2nm node will achieve significant power savings while improving performance and transistor density. In addition, the subsequent process technologies A16 and N2P are also expected to be put into production next year.

N2 is TSMC's new process technology, which will achieve the so-called "full node improvement". Compared with N3E, it will improve performance by 10% to 15%, reduce power consumption by 25% to 30%, and increase transistor density by 15%. TSMC stated that the transistor performance of N2 is close to the target, with an average yield of over 90% for the 256Mb SRAM module, indicating that the process has reached a mature level as N2 is gradually mass-produced.

N2 will be TSMC's first node to adopt GAA nanosheet transistors. Due to the gate surrounding the channel 360 degrees (the channel shape of N2 is multiple horizontal nanosheets), this technology is expected to improve performance and reduce leakage. This structure can maximize the electrostatic control of the channel, thereby minimizing transistor size without affecting performance or power consumption, ultimately achieving higher transistor density.

TSMC's N2 manufacturing process is expected to enter mass production in the second half of this year and will support numerous products launched next year, including AMD's next-generation EPYC "Venice" CPU for data centers and various client oriented processors, such as Apple's 2025 SoC for smartphones, tablets, and personal computers.
