In March 2026, Photo electron Soul raised JPY 900 million in venture funding from SHIBAURA MECHATRONICS CORPORATION, Higin Capital, and Hotung Investment Holdings.

Photo electron Soul specializes in advanced electron beam technologies, particularly the PES-2020 e-Beam System®, designed for semiconductor wafer inspection. This system boasts an electron beam brightness over ten times that of traditional Schottky emitters, facilitating precise measurements. The PES-2020 employs proprietary Digital Selective e-Beaming™ technology for multi-beam capabilities and customizable beam shapes, catering to the intricate demands of semiconductor manufacturing and high-tech industries. Photo electron Soul primarily engages in direct business-to-business transactions with semiconductor manufacturers and research institutions.
