FLOSFIA is a spin-off from KYOTO University, to commercialize the MISTDRY™ technology
FLOSFIA Inc., headquartered in Kyoto, Kyoto prefecture, Japan, is a spin-off from a research of Kyoto University, specializing in film-formation by mist chemical vapor deposition (CVD). Making use of physical properties of gallium oxide (Ga2O3), FLOSFIA has devoted to development of low-loss power devices. FLOSFIA succeeded in a development of a Schottky Barrier Diode (SBD) with the lowest specific on-resistance of any SBDs currently available on the market (through an internal investigation), realizing technologies linked to power loss reduction that is reduced up to 90 percent less than before. FLOSFIA will now develop its own production lines with a view to launching commercial production in 2018.FLOSFIA produces a variety of thin films, enhancing MISTDRY™ technology, achieving commercialization of power devices, and realizing application of its technology to electrode materials, oxide compounds with functional properties for electronic devices, plating and polymers.

2026-5-20 FLOSFIA Selected as a Finalist of the 2026 WIPO Global Awards
— One of 33 finalists chosen from over 1,300 applications across 126 countries, recognized for IP-driven innovation —
FLOSFIA is pleased to announce that it has been selected as a finalist of the 2026 WIPO Global Awards, organized by the World Intellectual Property Organization (WIPO), a specialized agency of the United Nations.
The WIPO Global Awards is the official international recognition program of WIPO, honoring SMEs, startups and university spin-outs that place intellectual property (IP) strategy at the core of their business growth and translate innovation and creativity into tangible solutions that benefit society. Established in 2022, the 2026 edition marks the fifth iteration of the program. Open to applicants from WIPO’s 194 Member States, this year’s edition attracted more than 1,300 applications from 126 countries, and FLOSFIA has been selected as one of the 33 companies advancing to the final round of evaluation.
Finalists are selected through a rigorous evaluation conducted by an independent international jury, based on the following four criteria:
－Business Case and IP Portfolio
－IP Commercialization Strategy
－IP Culture within the Company
－Impact for a Better Society
FLOSFIA has been advancing the commercialization of next-generation GaO™ power devices — power semiconductors that simultaneously deliver low loss, high breakdown voltage and low cost — built on a novel material first developed at Kyoto University, α-type gallium oxide (α-Ga₂O₃), together with its proprietary MIST DRY™ thin-film deposition technology. These technologies are systematically protected by a portfolio of patents, trademarks, designs and other IP rights in Japan and overseas, built up through a continuous IP strategy maintained since the company’s founding. We believe that this recognition by WIPO reflects the cumulative results of R&D and business development driven by these IP assets, together with ongoing efforts toward mass production and real-world deployment carried out in collaboration with multiple operating companies.
The 11 Winners will be unveiled at the WIPO Global Awards Ceremony held during the WIPO Assemblies at WIPO Headquarters in Geneva, Switzerland, on Friday, July 10, 2026.

2023-3-15 FLOSFIA and JSR progress toward practical use of the world’s first P-type semiconductor, Iridium Gallium Oxide
FLOSFIA Inc. (FLOSFIA) and JSR Corporation (JSR) announced today they have jointly developed a new iridium-based film deposition material as a solution for mass production of iridium gallium oxide (alpha-(IrGa)2O3). This is the world’s first P-type power semiconductor developed by FLOSFIA for use in combination with corundum-type gallium oxide (alpha-Ga2O3). The use of this material allows for mass production in industrial applications as well as the expression of P-type characteristics, which is the most important characteristic of iridium gallium oxide.
