Professor Bruce Smith has been a member of the engineering faculty at RIT since joining the Microelectronic Engineering program in 1988.  He is currently the Director of the Microsystems Engineering Ph.D. program and an extended faculty member with the Center for Imaging Science and the Center for Materials Science and Engineering.  He received B.S., M.S. and Ph.D. degrees in Imaging Science from RIT, concentrating on thin films, materials, and semiconductor lithography. Prior to joining the RIT faculty, he held R&D positions in semiconductor engineering at Digital Equipment Corporation in Hudson, MA and AMI Semiconductor in San Jose, CA.  Professor Smith and his group in the Nanolithography Research Laboratory carry out research in areas of micro- and nano-fabrication including nanolithography, semiconductor processing, thin film materials, and optical engineering.  Their work is directed toward leading edge electronic, photonic, micromechanical, and display devices and structures.  Professor Smith is a Fellow of the IEEE, a Fellow of the OSA, a Fellow of SPIE, and a member of AVS and ASEE.  

Professor Smith has received numerous research grants from federal agencies, research consortia, and industrial groups, totaling several million dollars.  He has published over 200 papers, presented over 50 keynote, plenary, or invited talks, authored several book chapters, and his textbook “Microlithography: Science and Technology” has become widely used worldwide for academics and professionals.  His publications have been cited over 2500 times and he has a citation h-index of 25. Professor Smith holds over 30 patents in areas including illumination systems, masking devices, optical system design, and semiconductor materials engineering, several of which have been licensed for commercialization.  Dr. Smith has been a key contributor in the development and adoption of excimer laser water immersion nanolithography, leading research efforts in the dominant technology for current semiconductor device manufacturing.

Professor Smith has been a pioneer in his field, leading to world-wide recognition of his accomplishments and those of his students.  Over the years, Professor Smith has developed first-of-a-kind courses in semiconductor lithography, materials, and processing that have been used as the basis for classes at universities worldwide. Additionally, he has pioneered unique engineering research experiences for both graduate and undergraduate students. Through support from Mentor Graphics Corp. and IMEC (Interuniversity Microelectronics Centre) he created the RIT/IMEC/Mentor Graphics Graduate Research Experience for extended student assignments with researchers at the IMEC consortium in Belgium.  The program has supported Ph.D. students from RIT and elsewhere for over ten years.  Through the US Department of Education, he established a Graduate Assistance in Areas of National Needs (GAANN) program for Ph.D. Study in Microsystems Engineering at RIT. He has also created collaborative research internships at SEMATECH, Intel, and GLOBALFOUNDRIES.  Among numerous grants from federal agencies, research consortia, and industrial groups, he has had over 15 years of continuous support through funding from the Semiconductor Research Corporation (SRC) for graduate research in semiconductor IC nanolithography.  Support through SRC has enabled student involvement with researchers from top IC companies from around the world.
