The factories outside Chennai, in India’s southern state of Tamil Nadu, are home to an array of global corporate names that lend credibility to Prime Minister Narendra Modi’s “Make in India” campaign, which aims to turn Asia’s third-largest economy into a workshop to the world.

The state’s industrial parks host international investors such as Renault-Nissan and Hyundai, which have large car factories; Dell makes computers there and Samsung produces TVs, washing machines and fridges. There are enough suppliers to Apple (including Taiwan’s Foxconn and Pegatron, and the Finnish contract manufacturer Salcomp) that people in Tamil Nadu’s business community commonly refer to the American tech group, which does not discuss its suppliers, as “the fruit company”. 

Now India wants to take a step up the manufacturing value chain, with a high-stakes bid to begin making semiconductors. The Modi government has put $10bn of incentives on the table to tempt manufacturers to set up new “fabs” (semiconductor fabrication plants) and encourage investment in related sectors such as display glass. One plant is being planned in Tamil Nadu.
