  • Patent number: 5981315
    Abstract: As the semiconductor chip is large-sized, highly integrated and speeded up, it becomes difficult to pack the semiconductor chip together with leads in a package. In view of this difficulty, there has been adopted the package structure called the "Lead-On-Chip" or "Chip-On-Lead" structure in which the semiconductor and the leads are stacked and packed. In the package of this structure, according to the present invention, the gap between the leading end portions of the inner leads and the semiconductor chip is made wider than that between the inner lead portions except the leading end portions and the semiconductor chip thereby to reduce the stray capacity, to improve the signal transmission rate and to reduce the electrical noises.

  • Patent number: 5334875
    Abstract: There is a trend to increase that area of a device requiring a memory of large capacity, which is occupied by a semiconductor memory. This trend obstructs reduction of the size of the device. The present invention contemplates to provide a memory which can have a high integration, a high density and a large capacity while minimizing the mounting area. In order to achieve this memory, the TAB (Tape Automated Bonding) of the prior art is mounted on an electrically conductive connector, and a plurality of structures composed of the TAB and the connector are stacked. Moreover, the connector mounting the TAB thereon is constructed such that the independent terminals of the stacked TABs may not be shorted.

  • Patent number: 5125821
    Abstract: A measuring device for enabling an evaluation of a moldability of a thermosetting resin by determination of parameters suitable for high accuracy forecasting of flow and curing behaviors of the thermosetting resin within a metal mold, as well as a metal mold for molding a thermosetting resin and method for constructing runners of the metal mold which is effective to minimize if not prevent the occurrence of false in moldings. By utilizing unique or peculiar parameters of the thermosetting resin which are not influenced by a molding condition and by conducting a flow simulation with a metal mold having a flow passage of arbitrary dimensions using the determined values for the parameters, a forecasting of a flow in an actual metal mold is enabled so as to preselect optimum molding conditions and flow passage dimensions for a metal mold.

  • Patent number: 5059559
    Abstract: The present invention relates to a multi-pin chip mounting method and apparatus based on a TAB (Tape Automated Bonding) system in which leads formed on a tape and bumps formed an IC chip are aligned with each other and compress-bonded to each other. An IC chip having bumps formed on a surface thereof and inner leads formed on a carrier tape are disposed opposite to each other at a bonding station. A position of the IC chip on a stage is detected through the inner leads at the bonding station to determine the amount of correction of position of the stage. The inner leads and the IC chip are aligned with each other on the basis of the determined correction amount and are thereafter bonded to each other.
