Abstract:
A structure and a method for packaging an image sensor chip. The structure includes: an image sensor chip and a substrate. The image sensor chip includes a first surface and a second surface that are opposite to each other, and the first surface is provided with multiple pixels configured to collect image information and multiple first bonding pads connected with the multiple pixels. The substrate covers the first surface of the image sensor chip, and is provided with wiring and a contact terminal connected with the wiring. A periphery of the image sensor chip is bonded to the substrate via an anisotropic conductive adhesive, the multiple first bonding pads are electrically connected with the contact terminal via the anisotropic conductive adhesive, and the anisotropic conductive adhesive surrounds all the multiple pixels and is not overlapped with the multiple pixels in a direction perpendicular to the substrate.
