This talk will discuss inkjet based high throughput manufacturing processes that possess nano-scale control in patterning, surface form, and material morphology. The research discussed here is driven by three themes (i) Creation of manufacturing building blocks - machines, materials, material delivery systems, and templates; (ii) Integration of building blocks via real-time and off-line algorithms to establish processes that meet nano-scale control, productivity and reliability metrics; and (iii) Optimization of these processes to enable future generation devices in electronics, displays, energy and biomedicine. The above three themes will be discussed first with respect to Jet and Flash Imprint Lithography (J-FILTM) that has demonstrated sub-10nm resolution and has been commercialized by Molecular Imprints, Inc. for ultra high density data storage including (i) solid state memory at sub-25nm half-pitch nodes and (ii) bit patterned media for terabit/in2 density hard disk drives. Next, extensions of inkjet based nanopatterning to roll-to-roll format will be discussed in the context of emerging applications in displays and advanced energy devices. Finally, two novel processes - adaptive thin film deposition and biomaterial nanofabrication - will be presented along with their potential applications.


S.V. Sreenivasan is Professor and Thornton Centennial Fellow in the Cockrell School of Engineering at UT-Austin. He is also a co-founder of Molecular Imprints, Inc., a technology spin-out from UT-Austin. He holds a Ph.D. in mechanical engineering from The Ohio State University. His research focuses on high throughput nanomanufacturing that enables ultra-high density memory, mobile computing devices, and applications in biomedicine and clean energy. He has published over 100 technical articles and holds over 90 U.S. patents. He has received several awards for his work including The Technology Pioneer Award from the World Economic Forum, The ASME Leonardo da Vinci Award, and the ASME William T. Ennor Manufacturing Technology Award.
