An image sensor packaging method, an image sensor packaging structure and a lens module are disclosed by the present invention provides. With the image sensor packaging method, a plurality of image sensor chips are embedded in a molding layer, thus allowing a greatly reduced thickness and improved slimness of the resulting packaging structure. Moreover, in this packaging method, instead of bonding wires, solder pads are externally connected by thin film metal layer formed on non-photosensitive surface area located on the same side as light-sensing surfaces. This allows a reduced impact on the light-sensing surfaces as well as a shorter distance from each solder pad to a corresponding one of the light-sensing surfaces along the direction parallel to the light-sensing surfaces, when compared to the use of bonding wires. As a result, the size of the image sensor chips is allowed to be further reduced, and using a packaging structure resulting from such image sensor chips to make a lens module is beneficial to space design thereof. For example, it can facilitate miniaturization of the lens module.

Image sensor packaging method, image sensor packaging structure, and lens module

An image sensor packaging method, an image sensor package and a lens module are disclosed. In the image sensor packaging method, plural image sensor dies are formed within a molded layer, resulting in a package with a significantly reduced thickness which is favorable to the slimming of the package. The packaging method does not involve any wire bonding process. Instead, metal pads are led out through a thin metal film formed in non-photosensitive areas on the same side of micro lens surfaces of the image sensor dies. This approach has a less adverse impact on micro lens surfaces and, compared to the wire bonding process, allows a smaller spacing from metal pads to the micro lens surfaces with respect to a direction parallel to the micro lens surfaces, which enables more compact image sensor dies usable in a lens module for an optimized spatial design and ease of miniaturization.
