Engineering Professor Awarded U.S. Patent for Methods and Apparatus of Manufacturing Micro and Nano-Scale Features

Dr. Salil Desai, associate professor in the Department of Industrial and Systems Engineering has been awarded United States Patent No. 8,573,757. His invention provides a method of generating scalable micro to nano patterned features on a substrate. The method involves ejecting a succession of droplets and altering their sizes in flight from micro to nano scale dimensions, thus giving control on the topography of the final 3D freeform features.  

This technology will enable researchers to deposit nano to micro droplets of different colloidal materials including metals, ceramics, polymers, bio-fluids, etc. Complex three-dimensional structures can be fabricated on curved surfaces at high throughput rates. This technology provides diverse applications in the fields of semiconductor electronics, photonics, NEM/MEMS, sensor development and regenerative tissue engineering.
