Prof. LIU Ran

Biography
Prof. Ran Liu received his B.S. degree at Fudan University in 1982, M.S. degree at Shanghai Institute of Technical Physics of Chinese Academy of Sciences in 1985, and Doctor of Natural Science at Max-Planck-Institute for Solid State Research and Stuttgart University, Germany, in 1990. He subsequently worked as research scientist at the University of Illinois at Urbana-Champaign, the University of Maryland, and the National Institute of Standard and Technology in USA from 1990 to 1996. From 1996 to 2004, he worked at Motorola as a Principle Staff Scientist and was actively involved in numerous materials/device research and development projects. He has authored and co-authored over 400 peer-viewed journal articles and conference papers.
 
Research Fields
His research interests are:
(1) Micro/nanoelectronics/optoelectronics technology - realizing miniature of electronic and optoelectronic devices, improving process integration and device performance;
(2) Advanced IC interconnect technology - introducing new concepts, materials and process to reduce interconnect resistance and parasitic capacitance for the purpose of IC power consumption and delay reduction;
(3) Micro-nano materials and structure technology - fabricating novel nano-materials and nano-structure to extend the application of nano-research field by utilization of nano-imprint/lithography technology;
(4) Flexible electronics technology - realizing smart low-cost and low energy consumption flexible electronics systems using organic and low-D materials and “flexible” processing technology.
