Abstract:
1. A manufacturing method of a wafer level chip scale package of an image-sensing module, the method comprising: providing a wafer that includes a plurality of die regions; forming a plurality of sensing units in each die region; forming at least one lens unit over the sensing units in the each die region, the at least one lens unit comprising a lens disposed in a sensing area and an edge wall disposed in a peripheral area next to the sensing area, where no lens is disposed, wherein the lens and the edge wall are of the same layer and the same material and a light-shielding film is formed on and in contact with a top surface or both the top and the bottom surfaces of the edge wall of the at least one lens unit; and performing a singulation process on the wafer with a cutting line passing through the edge wall to form a plurality of image sensor chips, wherein a cap layer is formed on the at least one lens unit subsequent to the step of the singulation process.
