In November 2023, Semicorex released 850V GaN-on-Si epitaxial products for high-voltage, high-current HEMT power device applications. Compared to other substrates for HMET power devices, GaN-on-Si enables larger wafer sizes and more diversified applications, and it can also be quickly introduced into the mainstream silicon chip process in fabs, which is a unique advantage for improving the yield of power devices.

Among the core components of electric vehicles, automotive power modules—primarily utilizing IGBT technology—play a crucial role. These modules not only determine the key performance of the electric drive system but also account for over 40% of the cost of the motor inverter.

The liquid phase method is closer to the thermodynamic equilibrium conditions and is able to grow SiC crystals with better quality.

Taiwan's Power Semiconductor Manufacturing Corporation (PSMC) has announced plans to build a 300mm wafer fab in Japan in collaboration with SBI Holdings. The purpose of this collaboration is to strengthen Japan's domestic IC (integrated circuit) supply chain, with a particular focus on circuits for AI edge computing and packaging technologies.

The wafer boats, loaded with a batch of wafers to be processed, are positioned on long cantilevered paddles.

The four main molding methods for graphite molding are: extrusion molding, molding, vibratory molding and isostatic molding. Most of the common carbon/graphite materials on the market are molded by hot extrusion and molding (cold or hot), and isostatic molding is a method with leading molding performance. Vibration molding is generally used to manufacture medium and coarse structural graphite, particle size between 0.5-2mm particle size, generally dominated by di-roasted graphitized products, density between 1.55-1.75kg/m³, coarser particles, rougher surface, can not be used for precision machining. It is mainly used in chemical industry and metal smelting.
