  • Patent number: 8410616
    Abstract: A surface component film (2) is etched using a resist (3) as a mask, and the surface component film (2) is patterned according to the shape of an aperture (3a). This results in a step portion (4) having the same shape as the aperture (3a), with the sidewall (4a) of the step portion (4) exposed through the aperture (3a). The aperture (3a) is spin-coated with a shrink agent, reacted at a first temperature, and developed to shrink the aperture (3a). To control the shrinkage with high accuracy, in the first round of reaction, the aperture is shrunk by, for example, about half of the desired shrinkage. The aperture (3a) is further spin-coated with a shrink agent, reacted at a second temperature, and developed to shrink the aperture (3a). In this embodiment, the second-round shrink process will result in the desired aperture length. The second temperature is adjusted based on the shrinkage in the first round.

  • Patent number: 8373276
    Abstract: Embodiments of the present invention provide a printed wiring board in which solder bumps of a mounted semiconductor chip are less prone to be ruptured. The printed wiring board includes a dielectric layer having a main surface and a connecting pad embedded in the dielectric layer. The connecting pad is shaped like a brimmed hat. That is, the connecting pad includes a plate portion whose diameter is larger than that of a contact portion. The main surface of the contact portion is exposed at the main surface of the dielectric layer. Diameter of the contact portion is substantially the same as diameter of an under bump metal at the semiconductor chip side, when mechanical stress is applied, the stress disperses evenly to both of the connecting pad and the under bump metal, and thus rupture is less prone to occur.

    Abstract: Method of fabricating thin-film transistors in which contact with connecting electrodes becomes reliable. When contact holes are formed, the bottom insulating layer is subjected to a wet etching process, thus producing undercuttings inside the contact holes. In order to remove the undercuttings, a light etching process is carried out to widen the contact holes. Thus, tapering section are obtained, and the covering of connection wiring is improved.

  • Patent number: 8253246
    Abstract: According to a simultaneous duel model that a de Broglie wave accompanies an electron drift-moving in an electron circuit, wiring is considered as a waveguide of the average de Broglie wave and design was performed by reducing the resistance value at bending portion of the wiring. Furthermore, by providing a micro-structure having a wave suppressing function of average de Broglie wave on the boundary between the metal electrode and the semiconductor electrode, so that electron transmitting probability at the boundary is increased. This improves electric feature of a macro structure portion which may cause a local heating such as a bending corner of wiring contained in the electronic circuit such as an IC and an LSI or a boundary between the metal electrode and the semiconductor electrode.

  • Patent number: 8247908
    Abstract: A circuit substrate and the method for fabricating a packaging of the circuit substrate are provided. A plurality of electrodes are formed on the surface of the circuit substrate, the electrodes are formed with fork structures over an connection section of the circuit substrate, so that when the circuit substrate expands/contracts due to thermal processes, the probability of alignment with electrodes of an external circuit board is increased by easily detaching the fork structure overlapping an electrode of the external circuit board which is not corresponding to the fork structure of the electrode of the circuit substrate, so as to avoid short circuit. Thus, electrode misalignment due to electrode pitch variation of the traditional circuit substrate as a result of thermal deformation can be effectively eliminated.

  • Patent number: 8242613
    Abstract: A semiconductor die has rows of bond pads along the edges of a major surface. The corners of the die are designated as keep out areas, with design layout rules prohibiting a probe-able bond pad from being placed in the keep out areas so that a minimum distance may be maintained between distal ends of adjacent rows of bond pads (i.e., bond pads along adjacent edges). The bond pads of each row have IO pad areas that are aligned with each other and IO probe areas that are aligned with each other. A generally L-shaped bond pad includes a first, vertical part that extends inwardly from an edge of the semiconductor die and a second, horizontal part connected to the vertical part. The L-shaped bond pad may be placed between a last bond pad in a row and a corner keep out area, and the second part of the L-shaped bond pad extends into the corner keep out area.
