  • Patent number: 6919622
    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.

  • Publication number: 20050101060
    Abstract: The present invention aims to improve the durability of an RFID chip inlet. A module including an RFID chip amounted to an antenna is covered with polyimide film with an adhesive layer to make up an RFID inlet. The outer surface of the RFID inlet is then covered with the surface processed to increase surface lubricity of a base part. When the RFID inlet is for use in a rubber product, it is mounted to a rubber base of the rubber product, the exposed surface of the RFID inlet is covered with an unvulcanized rubber, and the unvulcanized rubber is then pressed and heated causing the RFID inlet to be embedded in the rubber base.
