In the turbulent arena of the semiconductor industry, every technological innovation and cost optimization may be the key to rewriting the rules of the game. Recently, FOX, a start-up company incubated by Tohoku University in Japan, has been a rising star with its breakthrough low-cost large-scale production of gallium oxide wafers, illuminating the way forward for the semiconductor industry and causing an uproar around the world.
1. Gallium oxide: a shining star of the fourth generation of semiconductor materials
As an emerging ultra-wide bandgap semiconductor material, gallium oxide has shown incomparable application potential in many fields such as high-voltage power devices, ultraviolet photoelectric detection, and high-frequency communication due to its unique wide bandgap (about 4.8 eV), high electron mobility, and excellent chemical and thermal stability. Compared with the current mainstream silicon-based and gallium nitride materials, gallium oxide can not only operate stably at higher temperatures, but also achieve higher energy conversion efficiency and lower energy consumption, which is recognized as a strong candidate for the next generation of semiconductor materials.
2. OCCC Technology: A Catalyst for a Cost Revolution
FOX's core competency lies in its OCCC (Cold Container Oxide Crystal Growth) technology, a revolutionary innovation jointly developed by Tohoku University in Japan and C&A. Expensive precious metal crucibles are used in the traditional gallium oxide crystal growth process, which not only increases production costs, but also limits further improvements in crystal size and quality. The OCCC technology abandons this limitation and achieves efficient and stable growth of gallium oxide crystals without the use of precious metal crucibles through a unique crystal growth environment design, which is estimated to reduce the production cost to 1/100 of the existing method, that is, the cost is reduced by 99%, which is undoubtedly a huge impact on the field of semiconductor material production.
3. From the lab to mass production: FOX's ambitions
At present, Tohoku University and the C&A team in Japan have successfully cultivated high-quality gallium oxide crystals with a diameter of about 5cm (nearly 2 inches) using OCCC technology, which indicates that the technology has initially met the basis for industrial application. On this basis, FOX has clearly put forward its development plan: in the initial stage, it will focus on overcoming the technical problems of semiconductor-grade large-size, and aims to achieve a technological breakthrough in mass production of 6-inch wafers (about 15cm in diameter) by 2028. Behind this ambitious goal is FOX's full confidence in its own technical strength and accurate grasp of market demand.

4. Global layout: The gallium oxide race is in full swing
Globally, the research and application of gallium oxide is advancing at an unprecedented rate. China's Hangzhou Fujia Gallium Technology Co., Ltd. is one of the leaders. In September 2023, Fujia Gallium announced the start of the construction of a 6-inch gallium oxide monocrystalline and epitaxial wafer production line in Fuyang, Hangzhou, with an expected annual output of up to 10,000 pieces, which is not only a strong supplement to China's semiconductor industry chain, but also indicates that the global gallium oxide industry is about to usher in explosive growth.
5. Challenges and Opportunities: The Way Forward for FOX
Despite the bright future, the competition in the gallium oxide market is also intensifying. As more companies join this track, technological innovation, cost control and product quality have become the key factors that determine the success or failure of enterprises. For FOX, the advantages of its low-cost production technology have undoubtedly won it an opportunity in the market competition, but how to quickly expand production capacity, improve product quality, and effectively deal with potential intellectual property disputes while maintaining technological leadership will be the challenges it must face in its future development.
In addition, with the acceleration of the commercialization process of gallium oxide materials, the perfection of its upstream and downstream industrial chain will also become a key factor affecting the development of the industry. If FOX can actively build a partner network and promote upstream and downstream collaborative innovation in this process, it will undoubtedly further consolidate its leading position in the industry.
6. Conclusion: A new chapter in the semiconductor industry
Overall, FOX is leading the way for GaN oxide materials to reach a broader commercial future with its innovative OCCC technology and clear strategic planning. The significant reduction in cost not only brings new growth points to the semiconductor industry, but also provides strong support for the transformation and upgrading of the global electronics industry. With the continuous maturity of technology and the gradual expansion of the market, gallium oxide is expected to become a bright pearl in the semiconductor field and open a new chapter in the semiconductor industry. For FOX, this is not only an opportunity for it to make its own leap, but also a historical mission to contribute to the semiconductor industry. In this technological revolution of semiconductor materials, FOX is writing its own brilliant chapter with its unique attitude.
