What Is AlN Ceramic Substrate?

Aluminum nitride (AlN) is the only technical ceramic material with extremely high thermal conductivity and excellent electrical insulation properties. The main application area of AlN is electronic device packaging, used as an insulating heat dissipation substrate for electronic components. AlN ceramic substrates are considered to be the best substrate material for their excellent comprehensive performance. In the fields of power semiconductor devices, hybrid integrated circuits, antennas in the communication industry, solid relays, power LEDs, multi-chip packaging (MCM), etc., the demand for AlN ceramic substrates is growing.

Advantages of AlN Ceramic Substrates

• High thermal conductivity, up to 170W/(m·K) or more
• The thermal expansion coefficient matches that of Si and GaAs
• Excellent electrical properties (dielectric constant, dielectric loss, volume resistivity, and dielectric strength)
• Good mechanical properties, higher flexural strength than BEO ceramics, and can be sintered at normal pressure
• Non-toxic, environmentally friendly material

Application of AlN Ceramic Substrate

AlN Ceramic Substrates can be used with AMB, DBC, DPC, HTCC, and other processes to produce different types of products to meet the needs of different application scenarios.

1. AMB and DBC are mainly used for IGBT, and they are growing rapidly with the development of new energy and electric vehicles.
2. DPC-AlN is mainly used in the high-power LED market.
3. HTCC and LTCC are mainly used in the RF and military fields, especially the thermal conductivity of AlN HTCC multilayer substrate materials can be as high as (170~190) W/(m·K), and the thermal expansion coefficient is only 4.2×10^-6/°C, which is close to semiconductor material devices such as Si, GaAs, and GaN. It has high strength and good density, can meet the requirements of packaging airtightness, and has become the preferred substrate material and packaging material for high-power MCM.
