With a bandgap of about 4.6 eV, it promises lower power loss than silicon or silicon carbide. In 2026, Patentix and JTEKT Thermo Systems developed a 6-inch compatible film deposition system, a step toward mass production. The development highlights that semiconductor competition extends beyond GPU design to materials and manufacturing.","whyItMatters":"The material could reduce electricity waste in data centers running generative AI, where power efficiency is as critical as compute speed.","webCardHtml":"\u003cp\u003eThe AI boom has drawn attention to semiconductor stocks, but the electricity required to run and cool data centers is also a growing concern. Power semiconductors, which convert and control voltage, are essential for efficiency. Patentix, a startup from Ritsumeikan University, is developing rutile-type germanium dioxide (r-GeO₂) as a material with a bandgap of about 4.6 electron volts, far exceeding silicon carbide\u0026#39;s 3.3 eV. In 2026, the company and JTEKT Thermo Systems built a 6-inch compatible film deposition system and formed r-GeO₂ thin films on silicon wafers. The achievement moves the material closer to the larger substrates needed for mass production. The work shows that semiconductor competition involves materials and manufacturing equipment alongside chip design.\u003c/p\u003e","blueskyPost":"Patentix, a Ritsumeikan University startup, is developing rutile-type germanium dioxide for power semiconductors.
