Patent ID: 7250324

Claim:
A method for manufacturing an image sensor, the method comprising the steps of: providing a substrate having an upper surface and a lower surface; mounting a frame layer on the upper surface of the substrate to form a cavity together with the substrate; mounting a photosensitive chip, which is formed with a plurality of bonding pads, to the upper surface of the substrate, the photosensitive chip being located within the cavity; providing a plurality of wires to electrically connect the bonding pads of the photosensitive chip to the substrate; supplying an adhesive medium to the cavity; placing a transparent layer on the frame layer to cover the photosensitive chip so as to form the image sensor; and rotating the image sensor to make the adhesive medium be uniformly distributed over the upper surface of the substrate so that only a portion of each of the wires is encapsulated by the adhesive medium, the other portion of each of the wires and the bonding pads of the photosensitive chip are exposed, and particles within the cavity are adhered to the adhesive medium.
