Abstract: A photon-drive fingerprint identification module configured to detect a fingerprint of a finger is provided, and the photon-drive fingerprint identification module includes at least a light emitting unit and a light detecting semiconductor array. The light emitting unit is configured to emit a detecting light to the finger, and the finger and the fingerprint reflect the detecting light and turn it into a signal light. The light detecting semiconductor array includes a plurality of light detecting semiconductor units arranged in an array, and the light detecting semiconductor units are configured to receive the signal light reflected by the finger and generate a plurality of electrical signals. Each of the light detecting semiconductor units sequentially includes an antireflection structure, a first type doped semiconductor layer and a second type doped semiconductor layer. The first type doped semiconductor layer is stacked between the antireflection structure and the second type doped semiconductor layer.
