Silicon Nitride (Si3N4) wafers
Silicon nitride layers are highly resistant to heat and oxidation, and have many applications in micro-mechanics and micro-electronics. A thin film of silicon nitride is very hard, and can act as a membrane. LPCVD nitride wafers can be easily deposited and produce uniform, pure film. They are also a popular choice for passivation layers.
Here are some common specifications for GaN wafers:
