Global 6 Inch Silicon Carbide Single Crystal Substrate Market Growth 2025-2031

The global 6 Inch Silicon Carbide Single Crystal Substrate market size is predicted to grow from US$ 1083 million in 2025 to US$ 2477 million in 2031; it is expected to grow at a CAGR of 14.8% from 2025 to 2031.

Silicon carbide is an inorganic substance with the chemical formula SiC. It is made of raw materials such as quartz sand, petroleum coke (or coal coke), and sawdust (salt is needed to produce green silicon carbide) through high-temperature smelting in a resistance furnace. Silicon carbide is a semiconductor that exists in nature in the form of the extremely rare mineral moissanite. Since 1893, it has been mass-produced as powder and crystals for use as abrasives, etc. Among non-oxide high-tech refractory raw materials such as C, N, and B, silicon carbide is the most widely used and economical one, which can be called diamond sand or refractory sand.

Wafer refers to the cutting, grinding, and polishing of crystals along a specific crystal direction to obtain a clean single wafer with specific crystal planes and appropriate electrical, optical, and mechanical properties for growing epitaxial layers. Silicon carbide wafer is the core material of the newly developed wide bandgap semiconductor. The devices made with it have the characteristics of high temperature resistance, high voltage resistance, high frequency, high power, and radiation resistance. It has the advantages of fast switching speed and high efficiency, which can greatly reduce product power consumption, improve energy conversion efficiency, and reduce product volume. According to different electrical properties, silicon carbide wafer can be divided into two categories: semi-insulating silicon carbide wafer and conductive silicon carbide wafer. These two types of wafer are clearly used to manufacture discrete devices such as power devices and radio frequency devices after epitaxial growth.

At present, 6-inch SiC wafer still occupy the mainstream market, but 8-inch wafer are gradually penetrating. Compared with 6-inch wafer, the cost of 8-inch SiC wafer can be reduced by about 35%, and more wafers can be cut out with less edge waste, which greatly improves the effective utilization of materials. Therefore, domestic and foreign manufacturers are accelerating research and development, expanding production, and entering the 8-inch silicon carbide market.

6-inch silicon carbide single crystal substrates have promising market prospects due to their unique properties and wide-ranging applications. The demand for silicon carbide substrates is rapidly increasing in industries like automotive, aerospace, and energy, where the need for high-performance electronic devices is growing. The superior mechanical strength, thermal conductivity, and electrical performance of these substrates make them highly desirable for power electronics, high-frequency devices, and optoelectronics. Additionally, the large size of the 6-inch substrate allows for more efficient production and fabrication processes. These factors, coupled with the advancements in silicon carbide materials and manufacturing techniques, indicate a strong market potential for 6-inch silicon carbide single crystal substrates.
