AlN Substrate

Ascendus uses tape casting process to produce substrates. According to different metallization requests we also developed many subdivisions: as fired, lapped, polished and laser scribed(cut).


AlN have already helped to achieve very low thermal resistance in many different applications, such as LED, power modules, RF components, laser package …… We feel very happy to always approach new technologies and devote some efforts in it.
