China Silicon Carbide-Coated Manufacturers, Suppliers, Factory

Quartz (SiO₂) material is very similar to glass at first glance, but the special thing is that the general glass is made up of many components (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.), while the quartz contains only SiO₂ components, and the microstructure of its silicon dioxide tetrahedral structural units composed of a simple network.

In the semiconductor industry, quartz is widely used, and high-purity quartz products are even more important consumables in wafer production. The production of silicon single crystal crucibles, crystal boats, diffusion furnace core tubes, and other quartz components must use high-purity quartz glass products.

There are several materials currently under investigation, among which silicon carbide stands out as one of the most promising. Similar to GaN, it boasts higher operating voltages, higher breakdown voltages, and superior conductivity compared to silicon. Moreover, thanks to its high thermal conductivity, silicon carbide can be utilized in environments with extreme temperatures. Lastly, it is significantly smaller in size yet capable of handling greater power.

In order to introduce the SiC coated graphite susceptor, it's important to understand its application. When manufacturing devices, further epitaxial layers are required to be built on some wafer substrates.

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.

Silicon carbide substrate is a compound semiconductor single crystal material composed of two elements, carbon and silicon. It has the characteristics of large bandgap, high thermal conductivity, high critical breakdown field strength, and high electron saturation drift rate.
