If you understand how transformative 2nm is going to be, you have to understand Japan’s hope for Rapidus.

2nm is that shift that marks a major architectural transition for the semiconductor industry, shifting from FinFET (fin field-effect transistor) structures to GAAFET (gate-all-around FET) designs.

AI data centers are notoriously power-hungry. The jump from 3nm to 2nm is expected to offer:

• 25–30% Power Reduction: At the same speed, 2nm chips use much less energy.

• 10–15% Performance Boost: At the same power level, they run significantly faster.

Demand for 2nm is so huge. While TSMC and Samsung have already begun high-volume 2nm production (late 2025), Rapidus is hitting its milestones with surprising speed.
