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

Two key materials that stand out for use in power devices are silicon carbide (SiC), and gallium nitride (GaN). One key advantage that GaN and SiC have over silicon is that, for a given on-resistance they do not break down as readily as silicon due to a much larger band gap – the energy it takes to move electrons out of bonds with atoms in the crystal lattice and turn them into unbound
