China SiC Coated Barrel Manufacturers, Suppliers, Factory

Silicon Carbide (SiC) epitaxy is a key technology in the field of semiconductors, particularly for the development of high-power electronic devices. SiC is a compound semiconductor with a wide bandgap, which makes it ideal for applications that require a high-temperature and high-voltage operation.

Every country is aware of the importance of chips and is now accelerating the construction of its own chip manufacturing supply chain ecosystem to prevent another chip shortage problem. But the advanced foundries without next-gen chip designers would be the same as “Fabs without Chips”.

Porous graphite, also known as porous carbon or porous graphite material, is a graphite form that has been specially engineered to have an interconnected network of pores or voids within its structure.

As a third-generation semiconductor material, Gallium Nitride is often compared with Silicon Carbide. Gallium Nitride still demonstrates its superiority with its large bandgap, high breakdown voltage, high thermal conductivity, high saturated electron drift velocity and strong radiation resistance. But it is undeniable that, like Silicon Carbide, Gallium Nitride also has various technical difficulties.

The history of silicon carbide (SiC) dates back to 1891, when Edward Goodrich Acheson accidentally discovered it while attempting to synthesize artificial diamonds. Acheson heated a mixture of clay (aluminosilicate) and powdered coke (carbon) in an electric furnace. Instead of the expected diamonds, he obtained a bright green crystal adhering to the carbon. This crystal had a hardness second only to diamond, and was thus named carborundum. In 1904, French-Jewish chemist Henri Moissan discovered rare natural silicon carbide minerals while studying meteorite samples from the Diablo Canyon in Arizona, USA. He named these minerals moissanite, and his discovery earned him the 1906 Nobel Prize in Chemistry.

4H-SiC, as a third-generation semiconductor material, is renowned for its wide bandgap, high thermal conductivity, and excellent chemical and thermal stability, making it highly valuable in high-power and high-frequency applications.
