What is silicon nitride (SiN)?
Silicon-nitride, an inorganic material with the formula Si3N4, is a substance. It is an important ceramic structural material, with high wear resistance, inherent lubricity and high hardness. It is a atomic crystal and resists oxidation in high temperatures. It is also resistant to the impact of both cold and heat. It won’t be damaged if you heat it to over 1000degC and cool it quickly, then heat it rapidly. The excellent properties of silicon nitride are the reason why it is used in many mechanical components like bearings, turbines blades, mechanical sealing rings, permanent molds and more. Silicon nitride Ceramics are resistant to heat and are difficult to transfer. They can therefore be used to create the heating surfaces for engine components.
The future trend in the market will be silicon nitride-ceramic substrates
Semiconductors develop towards high-power and high-frequency semiconductors. Semiconductor products are used widely in many fields, including wind energy generation, solar photovoltaic electricity generation, electric cars, LED lighting, etc. Ceramic substrates, as electronic components, play an important role in the LED lighting field.
Semiconductor packing materials are substrates with good electrical insulation that contain electronic components and interconnections. The substrate should possess the following characteristics: high insulation and resistance against electrical breakdown.
Substrates that are commonly used include ceramic, glass ceramic, diamond, resin, silicon, metal, or metal composites. Ceramics, for example, have been a favorite because of their high thermal conductivity (higher than metal) and their high frequency characteristics.
