Application of aluminum nitride substrate

Aluminum nitride products are attracting more and more attention as a new generation of high thermal conductivity materials due to their superior thermal conductivity, high insulation, and thermal expansion rate close to silicon.


  1. High thermal conductivity: about 7 times the thermal conductivity of alumina
  2. Thermal expansion rate: thermal expansion is close to silicon, and the reliability of the mounting of large silicon wafers and heat-resistant cycles
  3. Electrical characteristics: high insulation, low dielectric coefficient
  4. Mechanical properties: superior to the mechanical properties of alumina
  5. Corrosion resistance: stronger than molten metal corrosion resistance
  6. Purity: low impurity content, non-toxic, high purity
