原版摘要:A wafer level packaging method and packaging structure. The wafer level packaging method compris: providing a device wafer integrated with a first chip, the
device wafer comprising a first front face integrated with the first chip and a first back face opposite to the first front face; forming a first oxide layer on the first front face; providing a cond chip to be integrated, the cond chip having a face to be bonded; forming a cond oxide layer on the face to be bonded; providing a bearing substrate; temporarily bonding the surface of the cond chip facing away from the face to be bonded onto the bearing substrate; by means of the cond oxide layer and the first oxide layer, implementing the bonding of the cond chip and the device wafer by using a fusion bonding process; after the bonding of the cond chip and the device wafer is implemented, debonding the cond chip and the bearing substrate; and forming a packaging layer covering the cond chip on the first oxide layer. The prent invention improves the bonding strength between the first oxide layer and the cond oxide layer by means of the fusion bonding process, thereby improving packaging finished product rate.
