Hitachi Unveils World's Smallest and Thinnest Contactless IC Chip
2025-08-19
Hitachi has announced the development of the world's smallest and thinnest contactless IC chip, measuring just 0.15 x 0.15 millimeters and 7.5 micrometers thick. Leveraging SOI technology to reduce the distance between circuit elements, the chip maintains the same functionality as its larger predecessor while boasting a quarter of the surface area and one-eighth the thickness. This results in over a tenfold increase in productivity. The breakthrough is expected to revolutionize applications for contactless IC chips across security, transportation, entertainment, traceability, and logistics.
