Abstract
A fingerprint sensing device comprising sensing circuitry comprising a plurality of sensing elements, each sensing element comprising a sensing structure arranged in a sensing plane and facing a surface of the capacitive fingerprint sensing device, each of the sensing elements being configured to provide a signal indicative of an electromagnetic coupling between the sensing structure and a finger placed on the surface of the fingerprint sensing device; and a plurality of connection pads electrically connected to the sensing circuitry for providing an electrical connection between the sensing circuitry and readout circuitry, wherein each of the connection pads is separately recessed in relation to the sensing plane such that each connection pad has a floor in a floor plane, and wherein each connection pad is separated from an adjacent connection pad through a portion of the sensing device being elevated in relation to the floor plane.
