Silevo brings together a strong team of innovators, disciplined semiconductor and solar factory operations talent, business executives, inventors and scientists with proven track records ramping products and revenues from the ground floor into billion dollar product lines and enterprises.

Dr. Zheng Xu
Dr. Zheng Xu is co-founder, president and CEO of Silevo. As one of the leading physical vapor deposition (PVD) scientists in the world, Dr. Xu is focused on making solar electricity more affordable through improved solar cell conversion efficiency and highly automated volume production technology at Silevo. His expertise in device physics and PVD for Transparent Conductive Oxides (TCOs) are core to Silevo’s groundbreaking Triex solar cell technology.

Dr. Xu has a rich history in the semiconductor industry. As a founding father and executive sponsor of the Endura Copper Barrier Seed PVD system, he helped semiconductor Integrated Circuit (IC) and Memory companies transition to copper-based interconnects in the late 1990s. This transition enabled rapid performance increases and cost reductions, and was influential in enabling the Internet and microelectronics age. 

Dr. Xu spearheaded these developments during his 15-year tenure as corporate vice president and general manager of CPI products business group at Applied Materials, Inc. Under his leadership, the CPI business group significantly improved product differentiation, market momentum and business performance, and achieved more than $1.2B revenue with 73% market share in the metal thin film market and more than 55% gross margin.

Dr. Xu spearheaded the development, market penetration and manufacturing cost reduction of leading-edge thin film products, for instance, PVD, atomic layer deposition (ALD) and Chemical Vapor Deposition (CVD) at Applied Materials. Dr. Xu also initiated new product development in Xi’an, China, and developed the first 300mm semiconductor equipment in that country.

Dr. Xu earned a Ph.D. in materials science from the University of California at Santa Barbara.   Dr. Xu also holds a Ph.D. in electrical engineering from Osaka University in Japan. He received his B.S. in semiconductor physics and devices from Zhejiang University in China. He holds 74 U.S. patents and has 13 pending U.S. patents.

Dr. Jianming Fu

Dr. Jianming Fu is a co-founder of Silevo, executive vice president and chief technology officer. He is responsible for developing Silevo’s industry leading Triex cell and module technology. Dr. Fu is also a leading Physical Vapor Deposition (PVD) scientist and innovator with extensive experience in product development.

Dr. Fu spent his early career driving PVD magnetron development, which is now embedded in nearly every semiconductor fabrication facility in the world. His in-depth knowledge and experience with magnetrons and PVD concepts is critical to Silevo’s unique technology, along with leveraging off-the-shelf proven production tools to enable new hardware modifications for solar innovation. At Silevo, he established device process capabilities, equipment, facilities and an experienced team of scientists to develop solar cells using tunneling junction with efficiencies over 20%.

Prior to his role at Silevo, Dr. Fu was heavily involved in product development in the PVD division at Applied Materials, Inc., where he served as general manager and managing director, as well as senior director of core PVD technology, a key R&D group focusing on new product and technology development for the division. Dr. Fu oversaw teams in China, India and the United States, and led the division to annual revenue of more than $400M with over 80% market share. In his 13 years at Applied Materials, he also launched multiple products as executive and inventor, including EnCoRe Ta/Cu, SIP Ti/TiN, Cu, ALPS Al, and successfully developed products for transition from 8” to 12” wafers. He is also one of the innovators who helped semiconductor IC & Memory companies transition to copper-based interconnects. 

In addition, he revolutionized PVD deposition by inventing self-ionized plasma (SIP) deposition technology, a process which ionizes up to 80% of metal atoms. SIP was quickly accepted in the market in 1997, with more than 100 SIP Al chambers shipped in the first year to DRAM makers such as Samsung and Micron, with derivative SIP products developed for Al, TiN, Cu and TaN. Today, SIP is used in virtually every leading semiconductor manufacturing facility in the world. 

Dr. Fu earned his Ph.D. in applied physics from Pennsylvania State University, his M.S. in semiconductor materials from the Institute of Semiconductors at the Chinese Academy of Sciences in Beijing, and a B.S. in physics from Wuhan University. He holds 63 U.S. patents.
