Abstract:
An image sensor chip package and a packaging method thereof are provided. The image sensor chip package includes: an image sensor chip having a first surface and a second surface opposite to each other, a photosensitive region being arranged on the first surface; a protective cover plate having a third surface and a fourth surface opposite to each other, the third surface covering the first surface; and a light shielding layer arranged on the fourth surface of the protective cover plate, the light shielding layer having an opening, and the photosensitive region being exposed through the opening. The light shielding layer includes a light absorbing layer located on the fourth surface and a metal layer located on the light absorbing layer.

Claim (Index 8):
An image sensor chip packaging method, comprising:\n providing a wafer, wherein the wafer has a plurality of image sensor chips arranged in an array, the wafer has a first surface and a second surface opposite to each other, and photosensitive regions are arranged on the first surface; providing a substrate having a third surface and a fourth surface opposite to each other; aligning and laminating the wafer with the substrate, wherein the first surface is covered by the third surface; and cutting the wafer and the substrate to form a plurality of the image sensor chip packages according to  claim 1 ; wherein a light shielding layer is formed on the fourth surface of the substrate, the light shielding layer has openings corresponding to the image sensor chips, and the photosensitive regions are exposed through the openings; and the light shielding layer comprises a light absorbing layer located on the fourth surface and a metal layer located on the light absorbing layer.
