China CVD SiC ring Manufacturers, Suppliers, Factory

There are six classifications for semiconductors, which are classified by product standard, processing signal type, manufacturing process, usage function, application field, and design method.

The tray (base) that supports SiC wafers, also known as a "susceptor," is a core component of semiconductor manufacturing equipment. And what exactly is this susceptor that carries the wafers?

Graphitising is the process of transforming non-graphitic charcoal into graphitic charcoal with graphite three-dimensional regular ordered structure by high-temperature heat treatment, making full use of electrical resistance heat to heat the charcoal material to 2300~3000 ℃, and transforming the charcoal with amorphous chaotic layer structure into ordered graphite crystalline structure.

When producing large-sized GaN single crystal substrates, HVPE is currently the best choice for commercialization. However, the back carrier concentration of the grown GaN cannot be precisely controlled.

Graphite is vital in producing Silicon Carbide (SiC) semiconductors, known for their exceptional thermal and electrical properties. This makes SiC ideal for high-power, high-temperature, and high-frequency applications. In SiC semiconductor manufacturing, graphite is commonly used for crucibles, heaters, and other high-temperature processing components due to its excellent thermal conductivity, chemical stability, and resistance to thermal shock.

Silicon carbide (SiC) ceramic materials possess a range of excellent properties, including high-temperature strength, strong oxidation resistance, superior wear resistance, thermal stability, low thermal expansion coefficient, high thermal conductivity, high hardness, thermal shock resistance, and chemical corrosion resistance. These characteristics make SiC ceramics increasingly applicable in various fields such as automotive, mechanical and chemical industries, environmental protection, space technology, information electronics, and energy. SiC ceramics have become an irreplaceable structural ceramic material in many industrial sectors due to their outstanding performance.
