While there is currently an oversupply of memory semiconductors due to a sluggish global economy, analog chips for automotive and industrial applications remain in short supply. Lead times for these analog chips can be as long as 40 weeks, compared to around 20 weeks for memory stocks.

The application areas of SiC-based and Si-based GaN are not strictly separated. In GaN-On-SiC devices, the cost of SiC substrate is relatively high, and with the growing maturity of SiC long crystal technology, the cost of the device is expected to fall further, and it is used in power devices in the field of power electronics.

The Silicon Carbide (SiC) production process encompasses the preparation of substrate and epitaxy from the materials side, followed by chip design and manufacturing, device packaging, and finally, distribution to downstream application markets. Among these stages, substrate material processing is the most challenging aspect of the SiC industry. SiC substrates are both hard and brittle, making cutting, grinding, and polishing extremely difficult. This increases the likelihood of defects during processing and reduces the yield rate. Currently, major international SiC manufacturers are planning to transition from 6-inch to 8-inch SiC wafers. Overcoming the challenges associated with 8-inch substrates has become a critical benchmark for the SiC industry. This article will introduce the key parameters of SiC substrates.

Silicon carbide (SiC) crystal growth furnaces are the cornerstone of SiC wafer production. While sharing similarities with traditional silicon crystal growth furnaces, SiC furnaces face unique challenges due to the material’s extreme growth conditions and complex defect formation mechanisms. These challenges can be broadly categorized into two areas: crystal growth and epitaxial growth.

With the development of semiconductor and optical technologies, glass wafers as the new type of glass product, are gradually becoming a complement to silicon wafers, showing great potential in the field of high technology. What are the glass wafers? Glass wafers are the high-performing circular thin slices, commonly made of quartz glass, alkali-free glass, or glass-silicon composites. With excellent physical and chemical properties, they play an irreplaceable roles in cutting-edge manufacturing fields, such as semiconductor manufacturing, optics, MEMS, consumer electronics, biomedicine, and laboratory research.
