MIND research center poised to meet demands of emerging nanotechnology

(Nanowerk News) The nanoelectronics industry has embarked on a quest for fundamental changes that will transform virtually everything it touches, according to Dr. Robert Doering, senior fellow and research strategy manager at Texas Instruments, one of the world's leading semiconductor companies.
And the Midwest Institute for Nanoelectronics Discovery (MIND), headquartered at the University of Notre Dame, is uniquely positioned to serve as an essential catalyst in that transformation.
Picture the entire city of New York ' including every person, animal, insect and plant, every graffiti scrawl on every building, every piece of litter tossed onto the sidewalk ' encrypted with pinpoint accuracy and stored on a tiny piece of silicon roughly the size of a postage stamp.
As impossible as it may seem, the field of semiconductors has miniaturized to the level where integrated circuits ('chips') of similar complexity are used daily in such technologies as cell phones, GPS devices and automated medical defibrillators.
'We've scaled down the incumbent chip technology so far that we will soon need something fundamentally different,' says Doering.
Scaling, the concept of producing ever-smaller components on integrated circuits, has driven IC technology for the past 50 years. The advantages of smaller components, including increased performance, more energy efficiency, lower costs, less space, expanded applications and larger markets, increase exponentially with each new level of scaling.
For a few more years, the existing technology can continue on its current trajectory, Doering said. However, sometime between 2015 and 2020, scaling of this technology will reach the point where it can go no further.
Thus, the search is on for a new way to make integrated circuits.
Speaking before a group of 155 key business leaders in South Bend, Doering outlined the scenario for the next monumental advance in semiconductor technology.
'What is the next transistor'? Doering asked the group gathered for the annual meeting of Project Future, which for 28 years has led economic development efforts in the South Bend area. 'We have some interesting concepts, but we haven't been able to verify the practicality of them yet. We're hoping to be there within the next few years, and MIND will be a crucial part of that.'
Researchers currently have several potential candidates under consideration. Depending on a number of variables, the successful technology could move in any of several directions.
'It's hard to predict the breakthroughs,' Doering said. 'We know some of the contenders, but we don't know which way they might go.'
It is precisely that unpredictability that places MIND ' one of four research centers funded by the Semiconductor Research Corp.'s Nanoelectronics Research Initiative -- in a uniquely strong position.
While the goal of all four NRI centers is to discover and develop the next nanoscale logic device, MIND is unique among the centers in its focus on two themes: energy-efficient devices and energy-efficient architectures.
'MIND is looking at overall efficiency and at overall evaluation of the new concepts against significant metrics,' Doering said. 'That puts South Bend on the map for funding. It also elevates the stature of Notre Dame in the university research community and rankings.'
Doering's visit highlights the widespread recognition of the research that is taking place at Notre Dame, according to South Bend Mayor Stephen J. Luecke.
'It's a recognition of the partnership between the university and the city to move projects forward to commercialization,' Luecke said, explaining that the city's commitment to support commercialization was a key factor in selecting the location for MIND.
'There is important work going on at MIND, and we're at the heart of it,' Luecke said. 'This focus on our community shows that we're moving in the right direction to create good opportunities.'
Some of those opportunities might arise from working with early adapters, Luecke speculated ' small companies that are very nimble and interested in research in a variety of venues. Such companies might not wait for the final big breakthrough, but are instead using individual elements now for existing or new products.
Doering's visit also highlights the area's preparedness to welcome the new technology as it emerges, according to Patrick McMahon, executive director of Project Future.
'Part of the reason we're very excited is that, as opposed to this being some intellectual property trying to find a home, the home is here,' McMahon said. 'It's here in the form of people who manufacture logic devices and the people who use them. The industry players are already identified for us, and our relationship with them is significant because of research occurring here.'
The fact that the technology will find its way into so many different types of products, applications and industries adds even more significance to what is already developing in South Bend.
'This is one of the largest innovations in 150 years,' McMahon said. 'Its impact will be more far-reaching than the auto industry.'
