Abstract
The present invention discloses a CMOS image sensor structure and packaging method thereof. The method includes the following steps: providing an image sensor chip and a transparent package substrate that is ground and cut, the front side of the image sensor chip being provided with an image sensing region and a pad region surrounding the image sensing region; bonding a first end of a metal wire onto the pad, the other end being suspended outside the image sensor chip; bonding the transparent package substrate and the image sensor chip having the metal wire to form an image sensor package, which can be assembled by surface mount technology (SMT) or pressure welding via the exposed and suspended metal wire. In the present invention, an auxiliary substrate is optionally used and an optical glass is directly fixed to the image sensor chip, and the image sensor chip is directly connected to a circuit board. The image sensor products using this packaging method have better performance, reliability, and ultra-low packaging costs.
