In this study, the results of direct wafer bonding of SiC-SiC at room temperature by standard surface-activated bonding (SAB) and modified SAB with a Si-containing Ar ion beam were compared, in terms of bonding energy, interface structure and composition, and the effects of rapid thermal annealing (RTA) at 1273K in Ar gas. Compared with that obtained by the standard SAB, the bonding interface obtained by the modified SAB with a Si-containing Ar ion beam is >30% stronger and almost completely recrystallized without oxidation during RTA, which should be due to the in situ Si compensation during surface activation by the Si-containing Ar ion beam.
