  • Patent number: 7652366
    Abstract: Output pads on an integrated circuit (IC) chip are arranged along a first longer side and are arranged along a second longer side with input pads. The output pads are connected to respective output patterns formed on top and bottom surfaces of a base film. All the output patterns may pass over the first longer side. Alternatively, the output patterns connected to the output pads at the second longer side may pass over a shorter side.

  • Publication number: 20060268213
    Abstract: Provided are a flexible film package module and a method of manufacturing the same that can be adapted for manufacture at lower cost and/or to adapt the characteristics of the flexible film package module for specific applications. The lower-cost flexible film package module includes a tape film that combines both a first insulating substrate, typically formed from a higher-cost polyimide material, and a second insulating substrate, typically formed from an insulating material or materials that are less expensive and/or provide modified performance when compared with the first insulating material. Both the first and second substrates will include complementary circuit patterns that will be electrically and physically connected to allow the composite substrate to function as a unitary substrate. The first and second substrates will also include connection regions that may be adapted for connection to printed circuit boards and/or electronic devices such as liquid crystal displays.
