Silicon Nitride | Morgan Technical Ceramics
Silicon nitride is produced in two main ways; Reaction Bonded Silicon Nitride (RBSN), and Hot-Pressed Silicon Nitride (HPSN) and Sintered Silicon Nitride (SSN). RBSN is made by direct reacting compacted silicon powder with nitrogen and produces a relatively low-density product compared with hot pressed and sintered silicon nitride, however the process has only a small volume change allowing

The packaging of SiC power devices has relied heavily on the same wire bonding approach used in silicon MOSFETs and IGBTs, largely because of its ease-of-use and low production costs. But while this suits the tens of kHz switching frequencies demonstrated by silicon devices, hit the much higher MHz speeds of SiC systems and parasitic inductances pose a problem.
