  • Publication number: 20170135119
    Abstract: In order to resolve the problem of various MVNOs being unable to always fairly share wireless resources of a mobile line network (wireless resources of all base stations), this system has base stations connected to a server, and when wireless resource use amounts related to prescribed groups (MVNO) are input from at least one base station, the server outputs, as information indicating the priority order of the groups, information corresponding to a prescribed number having a monotonic increase relationship with the sum of the use amount related to the group, for each of the groups. When the information indicating the priority order of the groups is input, the base station communicates with terminals by using the wireless resources in order from a terminal of the group with the highest priority indicated by the information.

  • Patent number: 8779603
    Abstract: Provided is a stacked semiconductor device (50) in which a semiconductor package (5) is stacked via connection terminals (8) on a semiconductor package (1), including a heat dissipating member (10) which is disposed between the semiconductor packages (1, 5), is brought into thermal contact with both of the packages (1, 5), and hangs over whole outer peripheral portions of the package (5). Such a structure causes heat generated from the package (5) to be released by heat dissipation into air above the package (5), heat dissipation into the air below the semiconductor package (5), heat transfer via the heat dissipating member (10) and a semiconductor element (3) to a first wiring substrate (2), heat transfer via the connection terminals (8) to the first wiring substrate (2), and heat dissipation via the heat dissipating member (10) into the air, thereby enhancing a temperature reduction effect of the semiconductor element.

  • Publication number: 20120313262
    Abstract: A stacked semiconductor device includes a plurality of first electrodes provided on a first printed wiring board and columnar electrodes provided on the first electrodes. The stacked semiconductor device also includes a plurality of second electrodes provided on a second printed wiring board and a plurality of solder electrodes. The columnar electrodes are formed of a material having a melting point higher than that of the solder electrodes, and the height of the columnar electrodes is set to increase as a distance between the first electrodes and the solder electrodes increases. This avoids connection failure without reducing joinability between two stacked semiconductor devices.

  • Publication number: 20110084405
    Abstract: In a stacking semiconductor device in which a first-layer and a second-layer semiconductor devices are stacked and bonded with a solder, warpage occurs due to a difference in thermal expansion coefficient of constituent members or a difference in elastic modulus of individual members. Therefore, between the first-layer and the second-layer semiconductor devices are provided an external connection terminal of solder and a thermosetting resin, and the stacking semiconductor device is heated at 150 to 180° C., which are the temperatures of preheating for reflow of the solder, for 30 to 90 seconds. Thereby the warpage of the first-layer semiconductor device is reduced and the thermosetting resin is cured completely in this state. Then, the temperature is raised to a reflow temperature of the solder and solder bonding using the external connection terminal is performed. Thereby, the bonding reliability of a solder-bonded portion of the stacking semiconductor device is considerably improved.
