  • Patent number: 7221049
    Abstract: A circuit device having a multilayered wiring structure and an excellent heat dissipation property, and a method of manufacturing the circuit device are provided. In a circuit device, a multilayered wiring structure including a first conductive pattern and a second conductive pattern is formed on a surface of a circuit substrate. A first insulating layer is formed entirely on the surface of the circuit substrate. The first conductive pattern and the second conductive pattern are mutually insulated by a second insulating layer. An amount and grain sizes of filler included in the second insulating layer are smaller than an amount and grain sizes of filler included in the first insulating layer. Therefore, it is easier to connect the above two conductive patterns by way of penetrating the second insulating layer.

  • Patent number: 7205673
    Abstract: A bond pad structure which includes an aluminum bond pad which include one or more dopants that effectively control the growth of IMC to a nominal level in spite of high tensile stresses in the wafer. For example, aluminum can be doped with 1–2 atomic % of Mg. Alternatively, Pd or Si can be used, or elements like Cu or Si can be used as the dopant in order to reduce the overall tensile stresses in the wafer. This can control the abnormal growth of IMC, thus arresting the IMC crack formation. A combination of dopants can be used to both control the tensile stresses and also slightly alter the gold-Aluminum interface thus enabling a uniform and thin IMC formation. This tends to reduce or eliminate any voiding or cracking which would otherwise occur at the wire bond transfer.

  • Patent number: 6882048
    Abstract: A lead frame used for the production of a semiconductor package, wherein each of terminals of the lead frame to be wire-bonded to electrodes provided on the top surface of the semiconductor device has one or two groove(s) for limiting a plating area of noble metal. Since grooves are provided in each terminal, the accuracy of the plating area can be easily checked visually. Further, the grooves absorb stress applied to the terminal when the molded semiconductor packages are individually separated from each other by punching or dicing, and the situation where molding compound comes off of the terminal is prevented. In addition, since the grooves absorb vibrational stress applied to the terminal after mounting a semiconductor on the printed circuit board, the reliability of assembly is improved.

  • Patent number: 6882030
    Abstract: To fabricate contacts on a wafer backside, openings (124) are formed in the face side of the wafer (104). A dielectric layer (140) and some contact material (150), e.g. metal, are deposited into the openings. Then the backside is etched until the contacts (150C) are exposed and protrude out. The protruding portion of each contact has an outer sidewall (150V). At least a portion of the sidewall is vertical or sloped outwards with respect to the opening when the contact is traced down. The contact is soldered to an another structure (410), e.g. a die or a PCB. The solder (420) reaches and at least partially covers the sidewall portion which is vertical or sloped outwards. The strength of the solder bond is improved as a result. The dielectric layer protrudes around each contact. The protruding portion (140P) of the dielectric becomes gradually thinner around each contact in the downward direction.
