Socionext begins development of cutting-edge '1.4-nanometer semiconductor'

Explanation

On July 1, 2026, Socionext, a semiconductor design company, announced that it would begin developing a cutting-edge semiconductor with a circuit line width of 1.4 nanometers. As a "fabless" company without its own manufacturing plants, it will commission Taiwan's TSMC to handle production for technical verification. Until now, designs down to 2 nanometers represented the cutting edge, but the company is taking on even finer circuits in anticipation of growing demand for AI servers. The narrower the circuit line width, the more transistors can be packed into the same area, boosting computing performance and power efficiency. Behind this move is the rapidly rising demand for "semiconductors that run faster while using less power" driven by the AI boom.
