Abstract :
We report a novel method for direct InP/SOI wafer bonding based on hydrophilic/hydrophobic treatment, which requires only a low annealing temperature of 320°C. Scanning acoustic microscope (SAM) measurements show that the proposed treatment helps form a firm bond between the wafer pair. The bonding strength is measured with a destructive approach, and the bonding interface is evaluated by scanning electron microscope (SEM).
