  • Patent number: 6600234
    Abstract: A semiconductor device includes a semiconductor substrate having bump electrodes and a sealing film formed thereon, the sealing film having laminated layers. The sealing film interposed between adjacent bump electrodes is prepared by laminating a protective film and each layer of the sealing film on the lower surface of the base film, on the bump electrodes, followed by allowing the bump electrodes to project through the sealing film under pressure and heat. The thickness of the sealing film is smaller than the height of the bump electrode, and thus the bump electrode projects through the sealing film. Particles for lowering the thermal expansion coefficient are dispersed in the sealing film to allow the sealing layers to exhibit a thermal expansion coefficient differing in its thickness direction such that the thermal expansion coefficient in the layer which is close to the semiconductor substrate is close to that of the semiconductor substrate.

  • Patent number: 6590877
    Abstract: A data transmission device is provided which can transmit data directed to a specific individual to a terminal in the vicinity of the specific individual. When a transmission event of data occurs, position data table of terminals, which the specific individual has a possibility to use, on a network is searched to extract the position data which coincides with or is the closest to the position of the specific individual at a present time or at an arbitrary time point in a given time period including the present time. The data is transmitted to a terminal corresponding to the extracted position data. Therefore, data can be transmitted to a terminal which is located in the vicinity of a specific individual and immediate accessibility of data transmission can thereby be improved.

  • Patent number: 6576288
    Abstract: Where the length LD of a resin film forming region is, for example, 3 times as long as the pitch of the sprocket holes of the base film, the resin coating is performed by using 6 nozzles, and where the length LD is, for example, 6 times as long as the pitch of the sprocket holes, the resin coating is performed by using 3 nozzles. As a result, the transfer distance of the base film transferred in a single resin coating process is 18 times as long as the pitch of the sprocket holes. It follows that it is possible to set constant the time for the base film to pass through the drying section even if the length LD of the resin film forming region differs.
