The invention provides a fingerprint imaging module and a formation method thereof, a fingerprint imaging module motherboard, and electronic equipment. The fingerprint imaging module comprises a substrate comprising a first surface and a second surface arranged in an opposite manner, a light-emitting stacking layer located on the second surface of the substrate and used for generating an incidentlight, a sensing surface on which a reflected light carrying fingerprint information is formed by the incident light, and a pixel array located on the first surface of the substrate and used for acquiring the reflected light to obtain fingerprint information. According to the technical scheme, the integration of a light source and an image sensor can be realized, the thickness of the fingerprint imaging module can be effectively reduced, and the integrated level of the equipment can be improved; besides, the thickness of the fingerprint imaging module is reduced, and the adoption of a module thinning process can be reduced so that the loss of the yield during formation of the fingerprint imaging module in the thinning process can be reduced, the manufacturing yield can be increased, and the cost can be lowered.
