"Silicon Nitride" in Semiconductors |

What's silicon nitride?

Silicon-nitride can be described as an inorganic material with Si3N4. It's a key structural ceramic material that has high hardness, intrinsic lubricity and wear resistance. It's an atomic crystal and is very resistant to oxygenation. Additionally, it is resistant to heat and cold. You can heat it to over 1000 degrees Celsius in air and cool it quickly. Then, you will be able to break the ceramic. This is because silicon nitride pottery has excellent mechanical properties. People use it often to create bearings, blades for turbines, seal rings and permanent molds. The heating surfaces of engine parts can be made from silicon nitride clays which can withstand high temperatures and transfer heat poorly. It can also improve engine quality, as well as fuel efficiency and fuel economy.

Future market will be silicon nitride ceramic sub-substrates

In the future, semiconductors will be high-power, low-frequency and integrated. Semiconductor technology can be found in many fields, including electric vehicles and wind power generation. Ceramic substrates, as electronic components play an important role in heat dissipation for LED lighting.

Semiconductor packaging materials contain electronic components, interconnections, as well good insulation. These properties should be present in your substrate: Good insulation; resistance to electrical break; thermal conductivity; direct thermal conductivity. This will affect operating conditions and last a long time.


There are many substrate materials currently in use: silicon substrates (metal or metal composites), ceramic substrates (glass ceramic substrates), diamond substrates (silicon substrates), resin substrates (silicon substrates), and ceramic substrates. Ceramics stand out because of their excellent insulation, stability chemical properties and high thermal conductivity.
