Introduction of Aluminum Nitride Ceramic Substrates

Aluminum nitride (AlN) is a ceramic material commonly used in bare ceramic substrates. It has two very important characteristics: high thermal conductivity, and the expansion coefficient (CTE) matching Si.
1. Aluminum nitride is currently the best thermally conductive material and is used in a variety of applications where heat needs to be transferred away from the component.
2. The low coefficient of thermal expansion makes AlN an ideal material for packages and submounts for power components such as power LEDs, high-power ICs, and high-voltage inductors.
