- Patent issued on new methods for fabrication of complex nanoscale devices
U.S. Patent 8,003,300, Methods for fabricating complex micro and nanoscale structures and electronic components and devices made by same, was awarded to K. Jain and U. Reddy on Aug. 23, 2011. The invention describes novel processing steps, methods and materials strategies for fabricating high-resolution structures for advanced electronic, optical and optoelectronic devices. The new methods are capable of making complex micro- and nano-scale structures, such as T-gates, gamma gates and shifted T-gates, having desired non-uniform cross-sectional geometries. The invention provides lithographic processing strategies for sub-pixel patterning in a single layer of photoresist and are useful for making and integrating device components comprising dielectric, conducting, metal or semiconductor structures having non-uniform cross-sectional geometries. The processing methods of this invention are complementary to conventional microfabrication and nanofabrication platforms, and can be effectively integrated into existing photolithographic, etching and thin-film deposition strategies, systems and infrastructure.

- PMML Initiative on Energy-Efficient Smart Window Technology Funded under Grainger Program in Emerging Technologies
- Professor Kanti Jain’s proposal on a novel Energy-Efficient Optoelectronic Smart Window Technology has been selected by the College of Engineering for funding under the Grainger Program in Emerging Technologies. The program was created by the Grainger Foundation to promote the transition of new academic developments in engineering into commercially viable products and services.
Current worldwide energy resources are becoming scarcer and more expensive every year while barriers (technological, financial, and political) to developing new energy sources remain significant. According to the Department of Energy, the cost of energy used for heating, cooling, and lighting in commercial and residential buildings in 2005 was a staggering $416 billion, a figure that is certainly much higher now. It has been further estimated that annual energy costs due to inefficient windows exceed $50 billion, and those for interior lighting, $70 billion. We are developing a novel smart window technology that will reduce losses, increase efficiency, and enable recycling of valuable energy resources. Our technology overcomes limitations of previous approaches, leading to dynamically programmable, energy-efficient window systems. This novel technology is an optoelectronic window system based on polymer blazed diffraction gratings constructed by microelectronic fabrication processes. The gratings are designed to enable dynamic control of the transmission of the visible and near-infrared solar radiation through the smart window. Since the benefits of the new technology include lower cooling costs during summer, lower heating costs during winter, and lower interior lighting costs all year, it will be applicable globally, without geographic or seasonal limitations.

- Jain group and collaborators win $6.3 million DARPA award for proposal on disruptive manufacturing technology
A team comprising University of Michigan at Ann Arbor (Professors Suman Das and John Halloran), University of Illinois at Urbana-Champaign (Professor Jain), Anvik Corporation, and Honeywell Aerospace has received a $6.3M, four-year award from DARPA for their proposal "Direct Digital Manufacturing (DDM) of Airfoils" in response to DARPA’s solicitation on "Disruptive Manufacturing Technologies." DDM of airfoils will be achieved by the processing of photocurable ceramic resins through a new direct digital manufacturing technology known as Large Area Maskless Photopolymerization (LAMP) being developed by the team. LAMP combines layered manufacturing of complex three-dimensional objects by solid freeform fabrication (SFF) with the fine-feature resolution and high throughput of massively parallel scanning maskless lithography to achieve a disruptive breakthrough in part build speed and feature definition. LAMP promises an unprecedented ability to rapidly manufacture parts that have macroscale exterior dimensions and microscale interior features.
