Abstract:
A method for manufacturing a fingerprint identification module is provided. In a step (a), a fingerprint sensor comprising a substrate, a sensing chip and a package layer is provided. The sensing chip is disposed on the substrate. The sensing chip is encapsulated by the package layer. In a step (b), an ink material is coated on the package layer, so that a color ink layer is formed on the package layer. In a step (c), a stamping tool is used to stamp the color ink layer, so that a top surface of the color ink layer becomes a first high gloss surface. In a step (d), the color ink layer to be heated through baking or irradiated with UV light, so that the color ink layer is hardened.
