摘要: A method of low temperature wafer bonding is provided. The method comprises: providing oxide to form a bonding layer on a deposition surface of at least one of two wafers, the bonding layer having a thickness in the range of 100 Angstroms to 500 Angstroms; soaking the wafers in a solution that makes bonding surfaces of the wafers hydrophilic; rinsing the wafers with water after soaking the wafers in the solution that makes bonding surfaces of the wafers hydrophilic; drying the wafers; optical-contact bonding the wafers with each other by bringing the bonding layers of the wafers in contact with each other to form a wafer pair; and annealing the wafer pair at a temperature less than or equal to 500° Celsius.
