According to the financial news agency reported, recently, known as the “ultimate power semiconductor”, the use of diamond power control with the development of the semiconductor progress. Japan Saga University professor Jia number professor and precision parts manufacturer Japan Orbray cooperation has developed a power semiconductor made of diamond and to 1 square centimeter 875 megawatts of power operation.

This power semiconductor has the world’s highest output power value among existing diamond semiconductors and is second only to gallium nitride products with approximately 2090 megawatts among all semiconductors. Compared with silicon carbide (SiC) and gallium nitride (GaN) products, which are the next generation of power semiconductors, diamond semiconductors have excellent resistance to high voltages and other properties, and power losses are thought to be reduced to one 50,000th of those of silicon products.

Diamond power semiconductors are also highly resistant to heat and radiation and are expected to become essential building blocks for artificial satellites, etc., by around 2050.

CVD(Chemical Vapor Deposition)Synthetic diamond is generally considered to be the best material for the preparation of next-generation high-power, high-frequency, high-temperature and low-power loss electronic devices due to its advantages of high pressure resistance, large radio frequency, low cost, and high temperature resistance. It is divided into polycrystalline diamond and single crystal diamond. Looking forward to the future, CVD artificial diamond can produce large-area single-crystal wafers through wafer splicing. As a semiconductor chip substrate, it can completely solve the problem of heat dissipation and utilize a number of super excellent physical and chemical properties of diamond to manufacture the fourth generation of "ultimate semiconductor material".
