The process of silicon carbide substrate is complex and difficult to manufacture. SiC substrate occupies the main value of the industry chain, accounting for 47%. It is expected that with the expansion of production capacity and the improvement of yield in the future, it is expected to drop to 30%.

The U.S. Department of Energy (DOE) recently confirmed a $544 million loan to SK Siltron, a semiconductor wafer manufacturer under SK Group.

​As the world searches for new opportunities in the semiconductor field, Gallium Nitride (GaN) continues to stand out as a potential candidate for future power and RF applications. However, despite its numerous benefits, GaN faces a significant challenge: the absence of P-type products. Why is GaN hailed as the next major semiconductor material, why is the lack of P-type GaN devices a critical drawback, and what does this mean for future designs?

Japan recently restricted exports of 23 types of semiconductor manufacturing equipment. The announcement has sent ripples across the industry, as the move is expected to have a significant impact on global supply chains for semiconductor manufacturing.

The third-generation wide bandgap semiconductor materials, such as Gallium Nitride (GaN) and Silicon Carbide (SiC), are renowned for their exceptional optoelectronic conversion and microwave signal transmission capabilities. These materials meet the demanding requirements of high-frequency, high-temperature, high-power, and radiation-resistant electronic devices. Therefore, they have vast application prospects in new-generation mobile communications, new energy vehicles, smart grids, and LED technologies. The comprehensive development of the third-generation semiconductor industry urgently requires breakthroughs in key core technologies, continual advancement in device design and innovation, and a resolution to import dependencies.

High-purity quartz possesses remarkable physical and chemical properties. Its inherent crystal structure, shape, and lattice variations contribute to exceptional characteristics such as high-temperature resistance, corrosion resistance, abrasion resistance, low thermal expansion coefficient, high insulation, piezoelectric effects, resonant effects, and unique optical properties. These attributes make it an irreplaceable foundational material for the development of strategic and pillar industries.
