Patent ID: 7345360

Claim:
A multi-chip image sensor module, comprising: a first substrate, which has an upper surface and a lower surface, wherein the upper surface is formed with a plurality of first connecting ends, and the lower surface is formed with a plurality of second connecting ends; a photosensitive chip, which is arranged on the upper surface of the first substrate, and electrically connected to the first connecting ends by a plurality of first wires; a lens holder formed with a through hole at a center thereof, wherein an internal thread is formed on an inner wall of the through hole, and the lens holder is mounted on the upper surface of the first substrate to encapsulate the photosensitive chip; a lens barrel arranged within the through hole of the lens holder and formed with an external thread, which is screwed to the internal thread of the lens holder, wherein the lens barrel is formed with a chamber and an opening communicating with the chamber; an aspheric lens and a transparent layer placed within the chamber; a second substrate having a first surface on which a plurality of signal output ends are formed, and a second surface on which a plurality of signal input ends are formed, wherein the first surface of the second substrate is mounted on the lower surface of the first substrate, and then the signal output ends are electrically connected the second connecting ends of the first substrate; and a lower chip located on the second surface of the second substrate and electrically connected to the signal input ends of the second substrate.
