摘要
A wafer level packaging structure for image sensors and a wafer level packaging method for image sensors are provided. The wafer level packaging structure includes: a wafer to be packaged including multiple chip regions and scribe line regions between the chip regions; pads and image sensing regions located on a first surface of the wafer and located in the chip regions; first dike structures covering surfaces of the pads and the scribe line regions; a packaging cover arranged facing the first surface of the wafer; and second dike structures located on a surface of the packaging cover. The second dike structures are arranged corresponding to the scribe line regions. The packaging cover and the wafer are jointed fixedly via the second dike structures and the first dike structures.
