Abstract: The present invention discloses a method for reducing the tilt of a transparent window during manufacturing of an image sensor. The method includes the following steps: providing a semimanufacture of the image sensor; carrying out a preheating process; carrying out an adhesive spreading process; carrying out a transparent window closing process; and carrying out a packaging process. By carrying out the preheating process, the environmental conditions can be stabilized during the adhesive spreading process and the transparent window closing process such that the transparent window can be kept highly flat after combining. By the implementation of the present invention, the chance of tilt and crack of the transparent window during manufacturing of the image sensor can be reduced, thereby achieving the goal for a better yield rate.

Abstract: An image sensor includes a substrate, a frame layer, a photosensitive chip, and a transparent layer. The substrate has an upper surface formed with a plurality of first connection points, and a lower surface formed with a plurality of second connection points. The frame layer has a first surface and a second surface and is mounted to the upper surface of the substrate with the first surface of the frame layer contacting the upper surface of the substrate so as to form a cavity together with the substrate. The second surface is formed with a rough contact surface. The photosensitive chip is mounted to the upper surface of the substrate and located within the cavity and is electrically connected to the first connection points of the substrate. The transparent layer is adhered to the rough contact surface.
