  • Publication number: 20050082647
    Abstract: A tape circuit substrate comprises a base film made of an insulating material, and a wiring pattern layer which is formed on the base film and has first leads that are connected to electrode pads arranged near a periphery of a semiconductor chip and second leads that are connected to electrode pads arranged near the center of the semiconductor chip. The semiconductor chip package comprises a semiconductor chip electrically bonded to the tape circuit substrate through chip bumps. In such a case, each of the leads is configured such that a tip end thereof to be bonded to the electrode pad has a width larger than that of a body portion thereof. According to the present invention, since the interval between the lead and the electrode pad can be made even narrower, a fine pitch semiconductor device can be realized.

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.

  • Patent number: 6849802
    Abstract: A semiconductor chip has connection lines that are routed to the side surface from bump pads on the back surface of the chip. Such semiconductor chips are stacked on a circuit board to form a chip stack package while bumps are interposed between the bump pads of the lower chip and bonding pads of the upper chip. Further, an interconnecting member such as a conductive adhesive or a wiring board is applied to the side surfaces of the stacked chips such that the connection lines are connected to the interconnecting member. Therefore, the centrally disposed bonding pads of the chips are electrically connected to the circuit board through the bumps, the bump pad, the connection lines and the interconnecting member. The semiconductor chip may have heat dissipation part formed on the back surface. Methods of manufacturing the semiconductor chip and the chip stack package are also provided.
