Abstract:
An image sensor, comprising:a substrate composed of plural spaced metal sheets, each of the metal sheets including a first board, a second board and a third board connecting the first board to the second board, wherein the first and second boards are located at different heights; a frame layer having an upper surface and a lower surface, the frame layer covering and sealing the metal sheets while exposing bottom surfaces of the second boards of the metal sheets, the frame layer being formed with a chamber on the lower surface thereof, bottom surfaces of the first boards of the metal sheets being exposed through the chamber, and a transparent region communicating with the chamber being formed on the upper surface of the frame layer; a photosensitive chip formed with a plurality of bonding pads and disposed within the chamber, the bonding pads respectively contacting the bottom surfaces of the first boards of the metal sheets in a flip-chip manner for signal transmission from the photosensitive chip, which receives optical signals passing through the transparent region of the frame layer; and a transparent layer mounted on the upper surface of the frame layer to cover the transparent region of the frame layer.
