Photo electron Soul Secures ¥900 Million Funding for Semiconductor Inspection Technology
Photo electron Soul has successfully completed a funding round totaling approximately ¥900 million, increasing its total funding to ¥4 billion. This capital will enhance production systems and support the development of next-generation electron beam applications, crucial for advancing semiconductor inspection capabilities.

On March 31, Photo electron Soul completed a funding round of approximately ¥900 million, raising its total funding to about ¥4 billion. Key investors include Shibaura Mechatronics, Higin Capital, and Hotung Venture Capital Corporation.
The company's flagship product, the PES-2020 e-Beam System, utilizes semiconductor photocathode technology and can produce an electron beam over 10 times brighter than Schottky, improving defect inspection speed. The funds will focus on mass production systems, next-generation application development, and expanding sales capabilities globally.
An evaluation for introduction at Kioxia Iwate is set to begin in late September 2025. The advancements may significantly impact semiconductor manufacturing efficiency.
