In addition, Steve has extensive M&A and corporate development experience, and was responsible for Leap’s profitable investment in the Chilean wireless operating company Smartcom PCS. Prior to Leap Wireless, Steve was senior director of product management for the CDMA Infrastructure Division of Qualcomm, where he focused on the development of world-class products for system-level applications including WLL, mobility systems, data systems, and advanced network solutions. He received his Bachelor of Science degree in physics from Boston College and a Master of Science in electrical engineering from Northeastern University. He also attended Boston College’s MBA program.


Dr. Paul Clifton, Vice President, Semiconductor

Dr. Clifton has broad experience in semiconductor process and device engineering, simulation and optimization gained over more than thirty years in industrial and academic R&D. Prior to joining Acorn Technologies, he worked on performance optimization, reliability, variability and yield ramp of multiple CMOS technology nodes as a semiconductor device specialist at PDF Solutions, a Silicon Valley-based provider of advanced process-design integration solutions to the IC industry. Before PDF Solutions, he held senior application engineering roles in TCAD at Silvaco, TMA, Avant! and ISE. He has specific process engineering expertise in plasma etch, CVD, MBE, including compound semiconductors and strained silicon. Paul has also worked as research team leader at the University of Newcastle on a pioneering development program for strained Si technologies in Europe.
