Overview of aluminum nitride ceramics

Aluminum Nitride Ceramic is an advanced ceramic material with aluminum nitride as the main component. It has been widely used in electronics, optics, and mechanics due to its unique properties.

Features of aluminum nitride ceramics

High thermal conductivity: Aluminum nitride ceramics have relatively high thermal conductivity, usually between 170-260 W/m·K, which makes it an excellent heat dissipation material. It is especially suitable for electronic devices that require efficient heat dissipation, such as substrate materials for power semiconductor devices.

Good electrical insulation: Despite its high thermal conductivity, aluminum nitride ceramics are excellent insulators of electricity, which can effectively prevent current leakage and ensure the safe operation of electronic components.

Low dielectric constant and dielectric loss: These characteristics make aluminum nitride ceramics very suitable for use in high-frequency circuits because it can reduce energy loss during signal transmission.

High temperature resistance: Aluminum nitride ceramics can maintain structural stability and strength at extremely high temperatures. Its melting point is about 2800°C, so it is suitable for applications in high temperature environments.

Low thermal expansion coefficient: Compared with semiconductor materials such as silicon, aluminum nitride has a lower thermal expansion coefficient, which means it has better dimensional stability when the temperature changes, which helps improve packaging reliability.

Corrosion resistance: Aluminum nitride ceramics have good chemical stability to most molten metals and are not easily oxidized or corroded, allowing them to perform well in harsh environments.

High mechanical strength: Although not as hard as some other types of ceramic materials, aluminum nitride ceramics still provide enough mechanical strength to allow them to be used in many structural applications.

Mechanical stamina is also notable. AlN sheets show high flexural strength, commonly above 300 MPa, guaranteeing structural stability under physical stress and anxiety.

Modification options consist of varying thicknesses, dimensions, and surface area coatings. Refined surfaces achieve roughness levels listed below 0.1 μm, crucial for specific semiconductor production procedures. Metallization layers like tungsten or gold can be included for boosted soldering or bonding. Flatness tolerances are tightly managed to stop bending throughout assembly.

Applications cover power electronics, LED modules, RF devices, and laser diodes. AlN substratums function as base plates, warm spreaders, or shielding layers. Their capacity to handle warmth and electrical power efficiently sustains miniaturization and higher power densities in modern electronics.

Processing methods include sintering at high temperatures to attain thick, pore-free structures. This ensures constant efficiency across sets. Material purity is kept over 99% to stay clear of impurities affecting electrical or thermal residential or commercial properties.

AlN ceramic sheets fulfill industry criteria for semiconductor-grade materials. They work with thin-film deposition methods, allowing integration into complicated circuits. Performance continues to be stable across temperature levels from -40 ° C to 1000 ° C, accommodating varied operating problems.
