Thintronics

Thintronics is a San Francisco-based advanced materials company reinventing the humble insulator - the dielectric films that sit between the copper layers of every chip and circuit board. Founded in 2019 by chemist Stefan Pastine, the company designs new insulating materials from the molecular level up, aiming to deliver faster, lower-loss, lower-power interconnects for AI data centers, high-speed networking, and RF/millimeter-wave systems. Its pitch is pointed: challenge the Japanese incumbent Ajinomoto, which has held more than 90% of the dielectric build-up film market for three decades, with a US-made alternative built for the terabit age.
