Companies divided over the size of chips they plan to make in India

Chips of smaller nodes are faster and more profitable, but their factories can cost as much as a nuclear power plant

Companies that have applied for India's financial incentive scheme to set up facilities to manufacture chips -- integrated circuits imprinted on silicon wafers -- are divided on the way forward. The bone of contention is the size of the nodes. Everyone knows small is the future of chip making. But there are deep schisms over the right size to start with, and how one should progress to smaller, more powerful, more sophisticated, and eventually more profitable chips.  

The Vedanta–Foxconn joint venture has said it would begin production with 28 nano metre (nm) chips, focusing on the consumer electronics and mobile
