  • Non-oxide Ceramics – Silicon Nitride (Si3N4)

    Silicon nitride is the main component in silicon nitride ceramics, which have relatively good shock resistance compared to other ceramics. In microelectronics, silicon nitride is usually formed using chemical vapor deposition (CVD) method, or one of its variants, such as plasma-enhanced chemical vapor deposition (PECVD).
