Abstract
An artificial retina chip module including a signal processing chip, a first polymer bump layer, and a photodiode array chip is provided. The signal processing chip includes a plurality of first pad disposed on a surface thereof. The first polymer bump layer includes a plurality of polymer bumps insulated from one another. Each of the first polymer bumps is composed of a polymer material and a conductive layer coated on the polymer material. Each first polymer bump is embedded into the corresponding first pad and the signal processing chip, wherein one end of the first polymer bump protrudes from the first pad and the other end thereof protrudes from a back surface of the signal processing chip. The photodiode array chip is disposed at one side of the signal processing chip and is electrically connected to the signal processing chip through the first polymer bumps.
