  • Patent number: 8050467
    Abstract: A sliding type thin fingerprint sensor package mainly comprises a substrate and a fingerprint sensor chip. The chip defined as a sliding region and a conductive portion comprises a dielectric layer, a circuit layer and a passivation layer. The circuit layer has a plurality of external contact pads and at least one electrostatic conductive pad close to a window of the dielectric layer. The passivation layer formed on the circuit layer has a plurality of first openings to expose the external contact pads and a second opening to expose the electrostatic conductive pad of the circuit layer and the window of the dielectric layer. The electrostatic conductive pad and the window are located at the sliding region and the external contact pads are located at the conductive portion. The fingerprint sensor chip is electronically connected with the substrate. A sensing region of the fingerprint sensor chip is exposed via the second opening of the passivation layer and the window of the dielectric layer.

  • Patent number: 7953257
    Abstract: A sliding type thin fingerprint sensor package defined as a sliding region and a conductive portion comprises a substrate, a fingerprint sensor chip and a metal plate. The fingerprint sensor chip is electrically connected with the substrate and a sensing region of the fingerprint sensor chip is exposed by a window of the dielectric layer. The metal plate is electrically connected with the substrate and a sliding surface of the metal plate is close to the sensing region of the fingerprint sensor chip. The sensing region and the sliding surface are exposed by the window of the dielectric layer. The sensing region of the fingerprint sensor chip and the sliding surface of the metal plate are located at the sliding region, and a plurality of external contact pads on a circuit layer of the substrate are located at the conductive portion.

  • Publication number: 20100141384
    Abstract: A bottle cap having anti-counterfeit function comprises a cap body and an RFID tag. The cap body has a cap portion, a ring neck portion and at least one joint portion, there is an interval between the cap portion and the ring neck portion, and the joint portion crosses through the interval and couples the cap portion and the ring neck portion. The RFID tag is disposed at the cap body and has an antenna and a chip electrically connected with the antenna. The antenna has a first antenna portion, a second antenna portion and a third antenna portion, the first antenna portion and the chip are disposed at the cap portion of the cap body, the second antenna portion is disposed at the ring neck portion of the cap body, and the third antenna portion crosses through the interval and bridge connects the first antenna portion and the second antenna portion.
