Hamamatsu Photonics K.K.

Hamamatsu supplies systems that narrow down a chip’s failure location between electrical testing and physical root-cause analysis with an electron microscope. Its May 2025 TD Imaging release describes detecting localized heat through laser reflectance to locate defects non-destructively. Semiconductor failure-analysis sales were ¥10.4bn in FY2025. Elsewhere in the group, medical-bio sales declined, while higher costs and other factors reduced operating profit. The business combines light-detection technology into equipment that helps customers take the next analytical step.
