The 2, 3, and 4-inch segment is the highest contributor to the market and is estimated to grow at a CAGR of 14.2% during the forecast period. SiC wafers of smaller sizes are more expensive for manufacturers to add since it is more difficult to add more semiconductors to them. New material for achieving a low-carbon society is a SiC wafer. Unlike silicon wafers, semiconductor devices such as transistors, diodes, and other devices are made using silicon wafers. SiC reduces power loss to 50% when employed in multiple electronic gadgets. It is appropriate for high-voltage, high-temperature uses in automotive (EV, HEV, etc.), photovoltaic power generation, and other applications in power electronics because it has an outstanding heat resistance and high-voltage qualities. The SiC substrate is currently 6 inches, and 8 inches are being developed. However, 4-inch wafers continue to be widely adopted. Cost reduction has not advanced significantly, and replacing equipment requires further capital investments. Additionally, the 6-inch now has a substantial production efficiency advantage.

The development of 150mm/ 6 inches SiC wafers has been a critical factor in the widespread market adoption of this technology. This has enabled the utilization of decommissioned 150mm silicon production lines, which can be adapted to make silicon carbide wafers meet the required criteria and the realization of manufacturing economies of scale. To improve the market adoption of SiC for use in bipolar devices, more significant, higher voltage-rated devices were developed to minimize prolonged crystal defects and regulate surface shape and flatness, two crucial components required by lithography processes. The low micropipe defect density was successfully managed by fine-tuning seed selection and development procedures. As an illustration, Dow Corning resolved these difficulties and provided 150 mm SiC substrates with warp, bow, and thickness variation metrics that complied with industry standards for handling in the processing lines. To solve the current and forthcoming electronics industry problems, Dow Corning manufactures and sells 4H-SiC 150 mm wafers.
