ABSTRACT:
A capacitive micro pressure sensing member and a fingerprint sensor using the same. The sensing member includes a substrate, a first suspended structure, a first protrusion structure, and a second suspended structure. The first suspended structure is located above the substrate and includes a suspended thin plate and at least one compliant suspension arm connected to the suspended thin plate, which is movable so that a distance from the suspended thin plate to the substrate is changed. The first protrusion structure is arranged at a center portion of a top surface of the suspended thin plate. The second suspended structure is arranged on a top surface of the first protrusion structure with a center portion of the second suspended structure contacting the first protrusion structure. The second suspended structure covers the first suspended structure to form a sealed chamber together with the substrate.
