Multibeam is managed by some of the brightest in Silicon Valley, including Dr. David K. Lam, founder and former CEO Fortune 500, Lam Research.

Dr. David K. Lam

Founder, Chief Executive Officer and Chairman of the Board

Recognizing the opportunity for e-beam direct-write lithography, Dr. Lam acquired key e-beam technologies and formed Multibeam in 2010. With its miniature columns, Multibeam developed the multicolumn e-beam lithography (MEBL) system which became the platform for advanced packaging, chip security, internet-of-things chiplet integration, rapid prototyping, and other applications. Dr. Lam is well known globally for his founding of Lam Research and his impact on the growth of the semiconductor industry. As founder and CEO of Lam Research, he led the development of industry’s first single-wafer, cassette-to-cassette, digital-controlled plasma etch system, ushering in the “sub-micron” chip era and launching the highly successful, Fortune 500 company. He was inducted into the Silicon Valley Engineering Hall of Fame in 2013 and received the MOCA Legacy Award from the Museum of Chinese in America in 2022. Dr. Lam holds Sc.D. and M.S. degrees in Chemical Engineering from the Massachusetts Institute of Technology and a B.S. Engineering Physics degree from the University of Toronto.

Dr. Ken MacWilliams

President and Multibeam Board Member

Dr. MacWilliams brings decades of experience in semiconductor device, process and equipment innovations. He joined Multibeam in 2020 to help productize the world’s first cost-effective direct write lithography system. Dr. MacWilliams has launched multiple novel equipment platforms and processes with the world’s leading semiconductor manufacturers. He held senior management positions with several high tech companies, including Applied Materials, Veeco, Yield Engineering Systems (YES) and Novellus (acquired by Lam Research). He holds Ph.D. and M.S. Electrical Engineering degrees from Stanford University. He is an NSF Fellow with over 100 publications and more than a dozen patents.

Eli Vronsky

Senior Vice President of Productization

Mr. Vronsky brings over 25 years of experience in the conversion of disruptive new technologies into commercial products, driving innovation, industry acceptance, and high volume growth.  While at Kateeva, he lead teams to bring new direct-write products to market in the display space.  These products serve leading-edge technology applications as well as high-volume production ramps globally for the world’s most demanding customers.

Ted Prescop

Vice President of Technology

Mr. Prescop leads the technology and application development of  Multibeam’s proprietary MEBL systems.  He has experience in semiconductor chip design, process development, and metrology at fabless foundries, KLA-Tencor and Veeco.  Mr. Prescop holds B.S. and M.S. degrees in Engineering Physics and Mechanical Engineering, respectively, from UC Berkeley.   

Roger Van Art

Senior Vice President Strategic Business

Mr. Van Art works closely with government and industry to develop new applications for use in semiconductor security, low volume/high complexity applications, and other electron beam direct write applications needed for defense, aerospace, and critical domestic infrastructure. His recent experiences include General Manager, Aerospace & Defense, at pure-play foundry Jazz Semiconductor as well as Vice President of Strategy, at Aeroflex Corp., a radiation-hardened fabless entity. His work in the government sector includes Branch Chief for the Directorate of Science & Technology in the Intelligence Community, collaborating with multiple US agencies. Mr. Van Art holds a B.S. degree in Electrical Engineering from Penn State.

Lynn Barringer

Treasurer and Multibeam Board Member

Ms. Barringer serves on the Multibeam Board and as Treasurer.  She previously held several active management roles in Multibeam during its corporate development.  She also has held numerous Director, Vice President, and CFO roles at top-tier companies, including Bank of America’s California Commercial Division, Conner Peripherals (now part of Seagate Technology), Avanti Corp, and JAFCO America Ventures.  She provides CFO advisory services and other guidance on the board to assure the success of Multibeam.  

Dr. David Lam
Chief Executive Officer and Chairman of the Board

Recognizing the opportunity for productive direct write lithography, Dr. Lam joined Multibeam in 2010. Dr. Lam is well known for his impact on creating what was later named ‘Moore’s Law’ when he developed the first single wafer, cassette-to-cassette plasma etch system and launched the > $60B semiconductor company, Lam Research. Dr. Lam is a regular invited speaker to lithography, semiconductor, and entrepreneurial events where he is a tireless advocate for the benefits of the company’s high productivity direct write multiple electron beam systems in solving the current challenges of security, internet of things chiplet integration, rapid prototyping, advanced packaging, and emerging applications across multiple semiconductor technologies.
