  • Patent number: 5057907
    Abstract: An integrated circuit package includes a plurality of TAB assemblies, each including a portion for inner lead bonding an integrated circuit. A portion of the tape is formed to allow the tape to be outer lead bonded to the substrate so that the integrated circuit is mounted at any desired non zero angle with respect to a horizontal substrate. A plurality of formed tape units are outer lead bonded to a horizontal substrate. In one embodiment, the die is inner lead bonded to the tape in an area which is not devoid of tape, allowing electrical traces on the tape which are routed above and not in contact with the surface of the die, thereby providing excellent routing density. The dielectric tape may include a single electrical interconnect layer, or a plurality of electrical interconnect layers which may themselves be electrically interconnected via suitable vias formed within the tape structure.
