A seemingly minor material challenge is now bottlenecking progress across the electronics industry: thermal management. As traditional solutions like aluminum oxide (Al₂O₃) and silicon nitride (Si₃N₄) struggle to meet the heat dissipation demands of modern devices, aluminum nitride (AlN) has emerged as the critical solution. Its unique properties are driving adoption across multiple high-tech sectors—but what makes AlN the material of the moment?
1. Addressing High-Power Density Challenges
5G/6G Communications: Base station power amplifiers (PAs) and RF modules require unprecedented thermal performance. AlN substrates deliver thermal conductivity (200–230 W/mK), dwarfing Al₂O₃ (30 W/mK).
Third-Generation Semiconductors: For SiC/GaN devices operating above 200°C, AlN’s thermal expansion coefficient (4.5×10⁻⁶/K) provides near-perfect semiconductor matching, minimizing thermal stress failures.
Advanced Packaging: In 2.5D/3D architectures, AlN interposers solve heat dissipation challenges in stacked chip designs.
2. New Energy and EV Applications
Power Batteries: AlN serves as an insulated thermal substrate in battery management systems (BMS), offering high-voltage resistance (>800V) and flame retardancy.
Automotive Electronics: Replacing Al-SiC composites, AlN substrates now cool IGBT modules and radar systems in electric vehicles.
3. Regulatory and Environmental Drivers
BeO Replacement: The EU’s RoHS directive has phased out toxic beryllium oxide (BeO), leaving AlN as the only safe, high-thermal-conductivity alternative.
Carbon Neutrality: Surging demand for clean energy equipment—photovoltaic inverters, wind power converters—is accelerating AlN adoption.
