Image sensor chip package method

An image sensor chip package method, comprising:

• providing a transparent substrate having an upper surface, a lower surface, and a plurality of through holes, wherein the through holes pass through the transparent substrate;
• forming a plurality of conductive posts in the through holes;
• forming a sealing ring on the lower surface of the transparent substrate;
• providing a chip having an active surface, an image sensitive area, and a plurality of die pads, wherein the image sensitive area and the die pads are located on the active surface;
• forming a plurality of conductive bumps respectively disposed on the die pads for respectively connecting the conductive posts;
• and
• turning the active surface of the chip to face toward the lower surface of the transparent substrate and assembling the chip to the transparent substrate, wherein the chip is electrically connected with the conductive posts via the die pads, and the sealing ring surrounds the image sensitive area and the die pads.
