Aluminum nitride is a new type of ceramic material with excellent comprehensive performance. It has excellent thermal conductivity and thermal shock resistance, reliable electrical insulation.
Because of the liquid phase sintering and no second phase at the grain boundary, the crystal structure is very dense and has good Resistance to plasma corrosion. A series of excellent characteristics such as low dielectric constant and dielectric loss, non-toxic and thermal expansion coefficient matching silicon, are considered to be ideal materials for a new generation of highly integrated semiconductor substrates and electronic device packaging and are widely used at home and abroad attention.
