China Solid silicon carbide Manufacturers, Suppliers, Factory

Japan recently restricted exports of 23 types of semiconductor manufacturing equipment. The announcement has sent ripples across the industry, as the move is expected to have a significant impact on global supply chains for semiconductor manufacturing.

The process of isostatic graphite manufacturing is Selecting raw materials, Blending, Molding, Isostatic pressing, Carbonization, Graphitization. 

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 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.

SiC MOSFETs are transistors that offer high power density, improved efficiency, and low failure rates at high temperatures. These advantages of SiC MOSFETs bring numerous benefits to electric vehicles (EVs), including longer driving range, faster charging, and potentially lower cost battery electric vehicles (BEVs). Over the past five years, SiC MOSFETs have been widely used in the power electronics of EVs in vehicles from OEMs such as Tesla and Hyundai. In fact, SiC inverters accounted for 28% of the BEV market in 2023.

Silicon carbide (SiC), as an important high-end ceramic material, has excellent properties such as high-temperature resistance, corrosion resistance, wear resistance, high-temperature mechanical strength, and oxidation resistance. These properties make it highly promising for applications in high-tech fields such as semiconductors, nuclear energy, defense, and space technology.
