Tata Group resorts to older tech to launch its chip foray

Tata Electronics Pvt. is preparing to make India’s first semiconductor wafers on far older technology than it originally expected, underscoring the challenges the country faces in trying to build a domestic chip industry from scratch.

The tech arm of the sprawling Tata conglomerate is preparing to build the country’s first large-scale chip fab or production plant mostly based on 90-nanometer process technology at its facility at Dholera in western Gujarat state, said people familiar with the matter, who asked not to be identified discussing private deliberations.
