Abstract
A fingerprint detection apparatus, a mobile device using the same and a manufacturing method thereof are provided. The fingerprint detection apparatus comprises an image sensing integrated circuit and a spatial filter disposed on the image sensing integrated circuit. The spatial filter has adjacent light tunnels for restricting an incident angle of light to the image sensing integrated circuit to prevent scattered light from entering the image sensing integrated circuit.
