Introduction
Aluminum nitride substrate is a new type of ceramic substrate, which has excellent thermal conductivity, high electrical insulation and thermal expansion similar to silicon. It can be used as a high thermal conductivity substrate material for power transistor module substrate, laser diode mounting substrate, IC packaging and other fields.Aluminum nitride substrate can also be used as electronic film material, applied in microelectronics and optoelectronics technology. Inaddition, due to its excellent corrosion resistance to halogen gases, aluminum nitride can also be used as a component in semiconductor manufacturing equipment.
Aluminum Nitride (AlN) is a advanced ceramic material with a range of notable properties and applications.
Key Properties
-
Thermal Conductivity: High (∼170-200 W/m·K), surpassing alumina (Al₂O₃), making it ideal for heat dissipation.
-
Electrical Insulation: Excellent dielectric properties, suitable for electronic substrates.
-
Mechanical: Hard, brittle, and refractory with a high melting point (~2200°C).
-
Chemical Stability: Resists oxidation but hydrolyzes in moisture:
Reaction: AlN + 3H₂O → Al(OH)₃ + NH₃↑ (requires dry handling). -
Piezoelectricity: Useful in sensors and resonators.
Synthesis
-
Methods:
-
Direct nitridation of aluminum powder with nitrogen at high temperatures.
-
Chemical Vapor Deposition (CVD) for thin films.
-
Sintering with additives (e.g., Y₂O₃) to enhance density, though purity is critical for optimal performance.
-
Applications
-
Electronics: Substrates for semiconductors, LED packaging, and heat sinks in power modules.
-
Optoelectronics: Used in UV LEDs and laser diodes due to wide bandgap (6.2 eV).
-
Piezoelectric Devices: Sensors, acoustic wave resonators, and MEMS.
-
Industrial: Crucibles for molten metals, composite fillers, and protective coatings.
