Scientists at the Indian Institute of Science (IISc), Bangalore have devised a new method to draw circuits in electronic chips which is more economically viable and energy efficient.

Economic Times reports Ph D candidate Santanu Talukder who began his doctoral research in 2012 along with his professors Praveen Kumar and Rudra Pratap has found an unique way to etch nano-circuits on silicon chips at room temperature..

Pratap who is also the chairperson of the Centre for Nano Science and Engineering of the institute told ET, "This is a game-changer because this makes the whole patterning technique affordable to a larger audience."

This new discovery was also featured in international scientific journal Nature and perhaps the most path breaking in the field since the 1960s. It is touted to bring the cost of chips to as much as one tenth of its present cost, but will take another two years to come to the market. The team had filed for a patent for the technology in 2014.

"The science is all sorted out, but the tech and engineering needs to be done. Patterning is one of the hardest tasks. The method we have developed could bring down the cost by a few millions on a single run. Moreover, it is energy-efficient and reduces the operating cost too," added Pratap.

"If this method actually works, it can be a game-changer in the Internet of Things industry due to the industry's need for low power and small form requirements," said Chinnu Senthilkumar, CTO of a VC firm floated by industry stalwarts Mohandas Pai and V Balakrishnan.
