Emeritus chemistry and CBE professor Jean Fréchet, a Professor of the Graduate School, has received a 2013 Japan Prize, one of the most prestigious international awards in science and technology.

Fréchet won the Japan Prize in Materials and Production jointly with UT Austin chemistry professor C. Grant Willson for their development of chemically amplified resist polymer materials for semiconductor manufacturing. Fréchet and Willson were honored for their work, which has significantly contributed to the development of our modern information society.

Willson is an alumnus of the chemistry department at UC Berkeley. He earned his B.S. in chemistry at Berkeley in 1962, and completed his doctorate in organic chemistry with Henry Rapoport in 1973. In 1993, he joined the faculty at the University of Texas at Austin, where he holds appointments in the Department of Chemistry and Biochemistry and in the Department of Chemical Engineering.

A second Japan Prize, in Biological Production and Biological Environment, was awarded to Rutgers University emeritus professor John Frederick Grassle for his contribution to marine environmental conservation.

These prizes reward those who have made a substantial contribution to the advancement of science and technology as well as to peace and prosperity of mankind. The award includes a certificate of recognition and a commemorative gold medal. A cash award of 50 million Japanese yen (approximately $560,000) is also given in each field.

Fréchet was born in France and received his first university degree at the Institut de Chimie et Physique Industrielles (now CPE) in Lyon, before coming to the United States for graduate studies in organic and polymer chemistry at the State University of New York, College of Forestry, and at Syracuse University.

He joined the chemistry faculty at the University of Ottawa in Canada in 1973 and remained there until 1987 when he became IBM Professor of Polymer Chemistry at Cornell University. In 1995 he was named to the Peter J. Debye Chair of Chemistry at Cornell University. In 1997, he joined the chemistry faculty at Berkeley and was named the Henry Rapoport Chair of Organic Chemistry in 2003 and Professor of Chemical Engineering in 2005.

While at Berkeley, Fréchet was also a senior scientist at the Lawrence Berkeley National Laboratory and served as a scientific director at LBNL’s Molecular Foundry.

In 2010 Fréchet became the vice president for research at King Abdullah University of Science and Technology (KAUST), Saudi Arabia. As a Berkeley emeritus professor and Professor of the Graduate School, he maintains an active research lab in Latimer Hall.

Fréchet and Willson began working together at the IBM San Jose Research Center in 1979, when Fréchet was a visiting scientist on a sabbatical leave from the University of Ottawa and Willson was a manager at the San Jose center.

At the time, semiconductor manufacturers were approaching the limits of the existing lithography processes and resist materials. Together with the late Hiroshi Ito, Fréchet and Willson invented chemically amplified resists that helped the fabrication of even smaller microstructures. These materials are now used to manufacture nearly all of the microprocessors and memory chips that are the heart of personal computers, mobile phones and many other electronic devices.
