FAQ

Q1: What is Aluminum Nitride(AlN)?
Aluminum Nitride (AlN) is a covalently bonded ceramic material formed from the two abundant elements, aluminum and nitrogen. It is highly stable in an atmosphere that is inert at temperatures over 2000°C and has a remarkable combination of properties, boasting high thermal conductivity and strong dielectric strength.T his makes it an indispensable material for thermal management and electrical applications.

Q2: What is Aluminium Nitride used for?
a. Heat sinks & Heat spreaders
b. Electrical insulators
c. Chucks and clamp rings for semiconductor processing equipment
d. Silicon wafer handling and processing
e. Substrates for electronic packages
f. Chip carriers for sensors and detectors
g. Laser heat management components
h. Molten metal fixtures
i. Packaging for microwave devices

Q3: Why is AlN a favored material for substrate and thermal management applications?
Aluminum Nitride is a one-of-a-kind ceramic material that offers both excellent thermal conductivity and high electrical resistivity. While Beryllium Oxide and cubic Boron Nitride also possess high thermal conductivity, usage of BeO is limited due to its toxicity and it is quite challenging to manufacture c-BN.

The capacity of a material to move heat while under the effect of a temperature differential is known as "thermal conductivity". In dielectrics such as AlN, heat transmission happens through lattice oscillations (or "phonons"). Elements having a straightforward composition, covalent bonding and low atomic mass normally demonstrate elevated thermal conductivity.

The thermal conductivity of a material is impacted by elements that hamper phonon dissemination. Such factors include temperature, impurities, pore size and placement, grain size, compositional homogeneity and alignment, all of which can significantly affect the lattice vibrations and, subsequently, the thermal conductivity.

The thermal conductivity of aluminium nitride, theoretically, is approximately 280 Wm-1K-1. The real thermal conductivity, on the other hand, is dependent on the processing parameters and the raw material quality. The incorporation of oxygen impurities into the lattice is a great disadvantage; as oxygen displaces nitrogen in the lattice, it forms vacancies that impede phonon propagation and scatter the phonons, thus leading to a decrease in thermal conductivity.
