摘要： A planar fingerprint pattern detecting array includes a large number of individual skin-distance sensing cells that are arranged in a row/column configuration. Each sensing cell includes an amplifier having an ungrounded input mode and an ungrounded output node. Output-to-input negative feedback that is sensitive to the fingerprint pattern is provided for each amplifier by way of (1) a first capacitor plate that is placed vertically under the upper surface of a dielectric layer and is connected to the ungrounded amplifier input node, (2) a second capacitor plate that is placed vertically under the upper surface of the dielectric layer in close horizontal spatial relation to the first capacitor plate and is connected to the ungrounded output node, and (3) an ungrounded fingertip whose fingerprint pattern is to be detected, which ungrounded fingertip is placed on the upper surface of the dielectric layer in close vertical spatial relation with the first and second capacitor plates. Electrostatic discharge protection relative to electrostatic potential that may be carried by the ungrounded fingertip is provided by placing a number of grounded metal paths within the dielectric layer to spatially surround each of the first and second capacitor plates, this being done in a manner that does not disturb the ungrounded state of the fingertip.

摘要： A planar, capacitive-type, rectangular, and multi-pixel fingerprint sensing array is mounted on the horizontal and generally rectangular top-surface of a dome that extends upward generally from the center of a horizontally disposed and generally rectangular silicon substrate member. The dome is formed by four upward extending and inclined, or tapered, side wall surfaces, at least one wall surface of which carries electrical circuit paths that electrically connected to the various circuit elements of the sensing array. A generally rectangular, encircling and wall-like card carrier assembly includes a generally horizontal upper-surface having a generally centered opening through which only the dome and sensing array project upward. The bottom-surface of the card carrier assembly is mounted to edge portions of the silicon substrate member in a manner to surround and protect all but the upward extending dome. A flexible membrane or laminate is sealed to the top-surface of the card carrier assembly to form a flexible surface over the sensing array. The card carrier assembly includes a circuit path having an external portion and having an internal portion that connects to the wall-mounted internal electrical circuit paths, the external portion providing external connection to the internal sensing array.

摘要： A variable capacitor in a semiconductor device is described in which the capacitance is varied by the movement of a dielectric material in the space between the plates of the capacitor in response to an external stimulus. A method of making such a variable capacitor is also described in which the capacitor is built in a layered structure with the top layer including a portion of dielectric material extending into the space between the capacitor plates. After formation of the top layer, an intermediate layer is etched away to render the top layer flexible to facilitate movement of the dielectric material in the space between the capacitor plates.

摘要： An improved fingerprint sensing device is provided with multiple sensing apparatus, two or more of which operating on different sensing principles. For example, a capacitive sensor may be integrally formed with an optical sensor on a single substrate. Ideally, the multiple sensing apparatus are disposed such that they may sense nearly identical portions of a fingerprint simultaneously. A primary sensor may be employed to establish the identity of a user based on a fingerprint, while a secondary sensor may be employed to establish that the fingerprint is part of a live human (anti-spoofing). Integrated light sources may be provided to drive an optical sensor. The light sources may also provide visual cues for usage, and enhance the aesthetics of the device.

摘要： An integrated leadframe and bezel structure includes a planar carrier frame, a plurality of bonding leads, a die pad region, and a bezel structure. The bezel structure includes a bending portion shaped and disposed to facilitate a portion of said bezel structure being bent out of the plane of said carrier frame. A sensor IC may be secured to the die pad region, and wire bonds made to permit external connection to the sensor IC. The bezel structure includes portions which are bent such that their upper extent is in or above a sensing surface. The assembly is encapsulated, exposing on the top surface part of the bezel portions and the upper surface of the sensor IC, and on the bottom surface the contact pads. Two or more bezel portions may be provided, one or more on each side of the sensor IC.
