Abstract
A fingerprint identification device includes a substrate, a piezoelectric layer, a conductive layer, and a planar layer. The piezoelectric layer is disposed on the substrate. The conductive layer is disposed on the piezoelectric layer, and the conductive layer has a rugged microstructure on an upper surface of the conductive layer. The planar layer is disposed on the conductive layer, and a bottom of the planar layer fills the rugged microstructure of the conductive layer.
