Abstract:
1. A wafer level image sensor packaging structure manufacturing method, comprising the steps of: providing a silicon wafer comprising a plurality of image sensing chips, the image sensing chips each comprising an image sensing region and a plurality of soldering pads; dicing the silicon wafer such that the silicon wafer is divided into the image sensing chips; providing a plurality of transparent lids by cutting at least one transparent panel; fabricating a plurality of semi-finished products each having the transparent lid correspondingly disposed above the image sensing region of the image sensing chip, wherein a air cavity is formed between the transparent lid and the image sensing region; performing a packaging process by filling an encapsulant between the semi-finished products such that the encapsulant only covers lateral sides of each of the semi-finished products; mounting solder balls on the soldering pads; and cutting the encapsulant between the semi-finished products.
