Ingantec names semiconductor veteran Dave Hemker to its board

By AI, Created 10:37 AM UTC, May 20, 2026, /AGP/ – Ingantec has appointed Dr. David J. Hemker to its Board of Directors as the Milwaukee materials science company pushes to commercialize InGaN-based platforms for microLED displays and photonics. Hemker will also lead the board’s Technology Committee and Technical Advisory Board, bringing more than 30 years of semiconductor industry experience.

Why it matters: - Dr. David Hemker’s appointment adds senior semiconductor and R&D leadership as Ingantec works to scale its InGaN-based platforms. - The move strengthens oversight of technology development, commercialization planning and technical investment decisions at the microLED startup. - Hemker’s background spans semiconductor equipment, venture-backed startups and multiple generations of chip manufacturing.

What happened: - Ingantec announced May 12, 2026, that Dr. David J. Hemker joined its Board of Directors. - Hemker will chair Ingantec’s Technology Committee and the company’s Technical Advisory Board. - Ingantec is a materials science company developing InGaN-based platforms for advanced microLED displays and photonics applications. - Alan Yeung, Ingantec’s chairman and CEO, said Hemker’s experience in scaling R&D and overseeing technology investments will support the company’s growth infrastructure and commercialization plans.

The details: - Hemker joined Lam Research in 1998 as Senior Director of New Product Development and retired in 2018 as Senior Vice President and Chief Technology Officer. - At Lam Research, Hemker led long-range research, technology development and technical venture investments before Lam Ventures existed. - Hemker served as board observer on investments including Molecular Imprints, Applied Microstructures and Replisaurus Technologies AB. - Lam equipment is used in virtually every leading-edge semiconductor node to date, according to the company. - Before Lam Research, Hemker was Vice President of Technology at Plasma & Materials Technologies, where he managed R&D, technology and engineering and served as the technical interface with the venture capital community ahead of the company’s 1995 IPO. - After PMT went public, Hemker helped guide the acquisition of UK-based Electrotech Ltd., which became Trikon Technologies. - Hemker began his career at Applied Materials in engineering and leadership roles. - Hemker said Ingantec’s III-Nitride optoelectronics address materials challenges in compound semiconductors and enable high-efficiency, small-form-factor red emitters that integrate with blue and green devices. - Hemker holds a B.S. in Chemical Engineering from the University of Wisconsin-Madison and M.S. and Ph.D. degrees from Stanford University. - Hemker has been named inventor on more than 100 patents worldwide.

Between the lines: - Ingantec is signaling that board-level technical governance is a priority as it moves from platform development toward commercialization. - Hemker’s mix of startup, public-company and venture investment experience suggests Ingantec wants guidance that covers both product scaling and capital strategy. - The appointment also reinforces Ingantec’s focus on compound semiconductor and photonics applications, not just display technology.

What’s next: - Hemker is expected to help guide Ingantec’s technology roadmap and advisory structure as the company scales its InGaN platform. - Ingantec’s next stage will likely center on commercialization of its microLED and photonics technologies. - The company did not announce additional board changes or a commercialization timeline in the release.
