Aluminum nitride aln ceramic metallized dbc substrate


What is Aluminum Nitride?

Known for its high thermal conductivity and electrical insulating properties, aluminum nitride is an excellent material for

making semiconductors. It is also used as a heat sink in light-emitter lighting technology.

Aluminum nitride is an inorganic compound of aluminium and nitrogen. It belongs to the wurtzite crystal structure and

has a band gap of 6 eV at room temperature. This makes it suitable for applications in deep ultraviolet optoelectronics.

It is also used as a circuit carrier in semiconductors.

Advantages of ALN

  • Uniform microstructure
  • High thermal conductivity* (70-180 Wm-1K-1), tailored via processing conditions and additives
  • High electrical resistivity
  • Thermal expansion coefficient close to that of Silicon
  • Resistance to corrosion and erosion
  • Excellent thermal shock resistance
  • Chemically stable up to 980°C in H2 and CO2 atmospheres, and in air up to 1380°C (surface oxidation
  • occurs around 780°C; the surface layer protects the bulk up to 1380°C).
