  • COLOR IMAGE SENSOR DEVICE AND FABRICATION METHOD THEREOF
    Publication number: 20080057614
    Abstract: A color image sensor device and fabrication method thereof. A passivation layer and a first planarization layer are sequentially formed on a substrate. A plurality of color filter elements are disposed over the first planarization layer corresponding to the sensor pixel array. A second planarization layer and a third planarization layer are sequentially formed over the first planarization layer. The third planarization layer has an opening formed corresponding to a contact pad. A third opening in the first planarization layer and the passivation layer corresponds to the contact pad.

  • Method, base station and mobile station for timeslot selection and timeslot assignment
    Patent number: 7116983
    Abstract: A timeslot selection method is provided. The timeslot selection method includes the steps of: obtaining a propagation loss; receiving an occupation state and an interference amount of an uplink timeslot; obtaining a desired wave power from the propagation loss; obtaining a ratio between the desired wave power and the propagation loss for the uplink timeslot in which the occupation state is idle; and selecting the transmitting timeslot by using the ratio. In addition, a timeslot assignment method in which there are a plurality of TDD boundaries each of which is a boundary between at least an uplink timeslot and at least a downlink timeslot in a frame is provided. Furthermore, a timeslot assignment method is provided, in which assignment is carried out according to a service class included in a QoS request.
