Abstract:
1. An image sensor module structure, comprising: a substrate having a horizontal upper surface on which first electrodes are formed, and a lower surface on which second electrodes are formed, wherein the first electrodes are correspondingly and electrically connected to the second electrodes; a photosensitive chip mounted on the upper surface of the substrate, and electrically connected to the first electrodes of the substrate by wires; a lens holder having an upper end face, a lower end face, and an opening penetrating through the lens holder from the upper end face to the lower end face, wherein an upper end portion of the opening is formed with an internal thread and a lower end portion of the opening is formed with a breach so that an internal diameter of the upper end portion of the opening is smaller than an internal diameter of the lower end portion of the opening, the lens holder is adhered to the upper surface of the substrate by glue, the photosensitive chip is located within the opening of the lens holder, the glue is filled within the breach of the lens holder and coated over the wires, the lens holder has a vertical inner sidewall and a vertical outer sidewall, the vertical inner sidewall is connected to the breach at a portion, which is located at a level higher than a level of the photosensitive chip, a portion of each of the wires is located under the breach, and an outer diameter of the lens holder corresponding to the internal diameter of the upper end portion of the opening is substantially equal to an outer diameter of the lens holder corresponding to the internal diameter of the lower end portion of the opening; and a lens barrel having an upper end face, a lower end face, and an external thread screwed to the internal thread of the lens holder.
