Embodiment
The above-mentioned purpose and its structure of the present invention and characteristic functionally, the preferred embodiment according to institute's accompanying drawings is given
Explanation.
As shown in Figure 1 and Figure 2, it is respectively the identification of fingerprint module first embodiment three-dimensional exploded view of the invention provided and group
Side view is closed, as illustrated, the identification of fingerprint module 1 that the present invention is provided is included：One substrate 11 and multiple fingerprint sensing units 12；
The substrate 11 has one first side 111 and one second side 112, and first side 111, the second side 112 are correspondingly arranged
In the upper side and lower side of the substrate 11, the material of the substrate 11 is glass or polymethyl methacrylate
(Polymethylmethacrylate), the present embodiment is using glass material as explanation embodiment, but is not limited thereto.
The plurality of fingerprint sensing unit 12 is closely adjacent to each other is divided into the second side 112 of the substrate 11, the plurality of fingerprint side by side
Sensing unit 12 has a basic unit 121, and the basic unit 121 is a silicon substrate.
The basic unit 121 has a first surface 1211, a second surface 1212, an inductive layer 1213 and a control
IC1214, the inductive layer 1213 is arranged at the first surface 1211, and the control IC1214 is arranged at the first surface 1211
And it is adjacent with the inductive layer 1213, the inductive layer 1213 has multiple induction electrodes and multiple cabling (not shown), and this is more
Individual induction electrode is electrically connected with the plurality of cabling with control IC1214, and the layer structure in foregoing inductive layer 1213 can refer to
