Image sensor module and method for manufacturing the same
First Claim
1. An image sensor module to be electrically connected to a printed circuit board, the image sensor module comprising:
- a plurality of lower metal sheets arranged in an array, each of the lower metal sheets having an upper surface and a lower surface;
a plurality of upper metal sheets arranged in an array, each of the upper metal sheets having an upper surface and a lower surface, the lower surfaces of the upper metal sheets being stacked on the upper surfaces of the lower metal sheets;
an encapsulant for encapsulating the lower metal sheets and the upper metal sheets, wherein the upper surfaces of the upper metal sheets are exposed from the encapsulant, the lower surfaces of the lower metal sheets are exposed from the encapsulant and electrically connected to the printed circuit board, and the encapsulant is formed with a frame layer around the upper surfaces of the upper metal sheets to define a chamber together with the upper metal sheets;
a photosensitive chip arranged within the chamber;
a plurality of wires for electrically connecting the photosensitive chip to the upper surfaces of the upper metal sheets;
a transparent layer arranged on the frame layer of the encapsulant to cover the photosensitive chip;
a lens holder formed with a chamber penetrating through the lens holder and an internal thread at a periphery of the chamber, the frame layer being fixed to the lens holder so that the transparent layer is located at a side of the chamber; and
a lens barrel arranged within the chamber of the lens holder, the lens barrel being formed with an external thread screwed to the internal thread of the lens holder, wherein the lens barrel is formed with a chamber penetrating through the lens barrel and has a transparent region and an aspheric lens in the chamber from top to bottom.

Abstract
An image sensor module includes an image sensor, and a lens holder and a lens barrel on the image sensor. The image sensor includes plural lower metal sheets, plural upper metal sheets stacked on the lower metal sheets, and an encapsulant for encapsulating the lower and upper metal sheets, wherein the upper surfaces of the upper metal sheets are exposed from the encapsulant, the lower surfaces of the lower metal sheets are exposed from the encapsulant, and the encapsulant is formed with a frame layer around the upper surfaces of the upper metal sheets to define a chamber together with the upper metal sheets. The image sensor further includes a photosensitive chip arranged within the chamber, plural wires for electrically connecting the chip to the upper surfaces of the upper metal sheets, and a transparent layer arranged on the frame layer to cover the chip.
