Abstract
A fingerprint detection apparatus, a mobile device using the same and a manufacturing method thereof are provided. The fingerprint detection apparatus comprises a substrate, an image sensing integrated circuit (IC), a light emitting circuit, a window layer and a molding material. The image sensing IC is disposed on the substrate. The light emitting circuit is disposed on the substrate and one side of the image sensing IC, and is electrically connected to the image sensing IC. The window layer is disposed on the image sensing IC, wherein light can pass through the window layer and enter the image sensing IC. The molding material surrounds the image sensing IC and blocks a light travelling path between the light emitting circuit and the image sensing IC to prevent the light emitted directly from the light emitting circuit from entering the image sensing IC and enhance the quality of fingerprint identification.
