2004 Purdue–Silicon Valley Symposia

Nano-Manufacturing

Nanoscale manufacturing – large, production scale manufacturing of nanoscale materials, structures and devices – presents a grand challenge to the engineering community. Over the last decade, progress has been made toward understanding fundamental phenomena at the nanometer scale and the unique properties of nano-engineered materials such as ultrahigh thermal conductivity, electrical conductivity, and mechanical strength. Researchers have also demonstrated nano-electro-mechanical systems (NEMS), integrating physical, chemical, and biological processes into micro to millimeter-scale packages, which could have an enormous impact on economy and national security. However, the current fabrication techniques are often limited to the laboratory scale. Over the next decade, the recently emerged research on nano-technology will influence not only how manufacturing should be done, but will also require entirely new manufacturing methods that are presently unavailable.

In his presentation, Xianfan Xu, Purdue University Professor of Mechanical Engineering, will describe some approaches to nano-manufacturing that are currently under development. He will also explain the nano-manufacturing research being conducted at Purdue. Purdue’s main efforts focus on the development of large scale nano-lithography/nano-manufacturing processes, development of techniques to assembly nanoscale materials to micro and millimeter scale components and systems, and on the development of low cost techniques for producing nano-crystalline materials. Xu will also discuss the new facilities for nano-manufacturing research, which will be housed in the $100M Birck Nanotechnology Center which is scheduled for completion in summer of 2005.

Joining Purdue University’s School of Mechanical Engineering in 1994, Professor Xianfan Xu currently directs the Center for Laser Micro-Fabrication at Purdue University. His present research focuses on laser-based micro and nano manufacturing, including nanoscale laser machining, high precision laser bending, development of bio and optical MEMS and NEMS, and near filed nano-optics.

Xianfan Xu earned both an M.S. and Ph.D. in Mechanical Engineering from the University of California, Berkeley. He is a recipient of the National Science Foundation Faculty CAREER Award as well as the Office of Naval Research Young Investigator Award.
