Abstract
The interfacial SiO2 layer of silicon wafer direct bonding has been studied in this paper. By means of AES and SEM, it has been found that interfacial SiO2 disintegrates into sphere-shaped islands with average radius much larger than the thickness of the native oxide layer, and is of amorphous material, SiO2, experimentally. The theoretical analysis shows that SiO 2 spontaneously disintegrates into islands in order to decrease the interface free energy as much as possible
