SiC opens up a lot of possibilities for costs-, size- and performance improvements at system level. This is especially true for high-switching frequency appliions. However, implementation of SiC comes with several challenges requiring best-in-class packaging.
The direct bonding method is applied to the GaN/SiC system, and the processing conditions for successful direct bonding are clarified. Direct bonding of GaN/SiC is achieved at 900°C. The direct bonding of GaN to Si-face SiC is very dependent on the choice of chemical treatments, but the bonding of GaN to C-face SiC is less dependent on surface preparation. If a native oxide is present when
Silicon nitride (Si3N4) bonded silicon carbide (SiC) material is produced by adding industrial silicon paste into artificial aggregate. Under high temperature, Si and N2 reacts with the formula of 2N2+3Si=Si3N4, Si3N4 bonded Sic material is formed by bonding SiC particles tightly.

Silicon carbide is formed in two ways, reaction bonding and sintering. Each forming method greatly affects the end microstructure. Reaction bonded SiC is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon.
Silicon carbide (SiC) has been widely investigated for use in high-power, high-temperature and high-frequency elec-tronic devices due to its superior intrinsic properties.1) To fabrie these devices, superior processing techniques are highly necessary. Dry
