Abstract:
1. An image sensor package comprising: a first substrate having a supporting surface and a bottom surface opposite to the supporting surface, the first substrate defining a cavity at the bottom surface, the cavity being ladder-like and comprising a wide portion and a narrow portion communicating with the wide portion, a step surface being defined at a bottom of the wide portion with a plurality of electrical connection points defined thereon; an image sensor chip disposed on the supporting surface and electrically connected to the first substrate; a second substrate; a processing chip disposed on and electrically connected to the second substrate; and a plurality of passive elements disposed on and electrically connected to the second substrate; wherein the second substrate, the processing chip and the passive elements are received in the cavity, the second substrate includes a top surface for supporting the processing chip, a plurality of soldering points disposed on the edge of the top surface of the second substrate, and wherein the soldering points are mechanically and electrically connected to the plurality of electrical connection points of the step surface to electrically and mechanically connect the second substrate to the first substrate.
