A diffusion furnace is a specialized piece of equipment used to introduce impurities into semiconductor wafers in a controlled manner. These impurities, called dopants, change the electrical properties of semiconductors, allowing different types of electronic components to be made. This controlled diffusion process is critical to the production of transistors, diodes and integrated circuits.

The current third-generation semiconductors are primarily based on Silicon Carbide, with substrates accounting for 47% of device costs, and epitaxy accounting for 23%, totaling approximately 70% and forming the most crucial part of the SiC device manufacturing industry.

Gallium Nitride (GaN) is an important material in semiconductor technology, known for its exceptional electronic and optical properties. GaN, as a wide-bandgap semiconductor, has a bandgap energy of approximately 3.4 eV, making it ideal for high-power and high-frequency applications.

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.
