what is SiC subatrate
A SiC substrate refers to a wafer made of silicon carbide (SiC), which is a wide-bandgap semiconductor material that has excellent electrical and thermal properties. SiC substrates are commonly used as a platform for the growth of epitaxial layers of SiC or other materials, which can be used to fabricate various electronic and optoelectronic devices, such as high-power transistors, Schottky diodes, UV photodetectors, and LEDs.
SiC substrates are preferred over other semiconductor materials, such as silicon, for high-power and high-temperature electronics applications due to their superior properties, including higher breakdown voltage, higher thermal conductivity, and higher maximum operating temperature. SiC devices can operate at much higher temperatures than silicon-based devices, making them suitable for use in extreme environments, such as in automotive, aerospace, and energy applications.

Industrial chain
The silicon carbide SiC industrial chain is divided into substrate material preparation, epitaxial layer growth, device manufacturing and downstream applications. Silicon carbide monocrystals are usually prepared by physical vapor transmission (PVT method), and then epitaxial sheets are generated by chemical vapor deposition (CVD method) on the substrate, and the relevant devices are finally made. In the industrial chain of SiC devices, due to the difficulty of substrate manufacturing technology, the value of the industrial chain is mainly concentrated in the upstream substrate link.
ZMSH company provides provides 100mm and 150mm SiC wafers. With its hardness (SiC is the second hardest material in the world) and stability under heat and high voltage current, this material is being widely used in several industries.
