Senior Vice President and Chief Technology Officer

James A. O’Neill, Ph.D.

Jim has been our senior vice president and chief technology officer since September 2015. He is responsible for the innovation process within the company including the development of new products and the global technology centers where Entegris collaborates with customers – the leading manufacturers of semiconductors – to solve their most complex technology challenges.

Jim joined Entegris in 2014 as part of our acquisition of ATMI, where he was senior vice president of Electronic Materials. Prior to that, he worked at IBM for 23 years where he held several technical and leadership roles in semiconductor research, development, and manufacturing. In one of those assignments, Jim set up and ran IBM's research operation at Albany Nanotech from 2007 to 2010 focused on the development of IBM's 14 nm node technology.

Jim earned a Ph.D. in physical chemistry at Columbia University and a Bachelor of Science degree in chemistry from Yale University. He holds 19 U.S. patents and has 46 technical publications.
