PDF Solutions announced that its Exensio analytics platform has helped DENSO Corporation’s 300mm IGBT manufacturing line achieve significant yield and output improvements. The company’s president of Japan Business Affairs, Michael Keleher, said the partnership has been in place for several years and that the platform’s ability to integrate data from multiple production facilities has accelerated the ramp to production‑level yields and enabled the launch of new high‑yield products.
DENSO’s 300mm IGBT line is a critical component of its electric‑vehicle power‑electronics portfolio. By feeding metrology, test, and equipment‑log data into Exensio, DENSO was able to identify root causes of defects more quickly and reduce scrap. While the exact percentage improvement was not disclosed, the company reported a clear increase in yield and output that has already translated into higher production volumes.
The win is especially noteworthy because DENSO is one of the world’s largest automotive parts manufacturers and has been working with United Semiconductor Japan to scale 300mm IGBT production for EV applications. The partnership underscores the growing importance of high‑yield IGBTs in power‑electronics supply chains and positions PDF Solutions as a key enabler for automotive leaders.
PDF Solutions’ own business context supports the significance of the win. The company reported record Q3 2025 revenues of $57.1 million, up 23% year‑over‑year, and reaffirmed its 2025 revenue growth guidance of 21‑23%. The Exensio platform, now enhanced with AI capabilities, is a core driver of that growth and is being adopted by a broader set of semiconductor customers.
The announcement is a material development for PDF Solutions because it confirms the value of its core product to a major automotive customer and signals potential for further expansion in the high‑yield IGBT market. The win strengthens the company’s competitive positioning, validates its AI‑driven analytics strategy, and could attract additional automotive and power‑electronics customers in the coming years.
