  • Patent number: 7375401
    Abstract: A semiconductor thin film is formed having a lateral growth region which is a collection of columnar or needle-like crystals extending generally parallel with a substrate. The semiconductor thin film is illuminated with laser light or strong light having equivalent energy. As a result, adjacent columnar or needle-like crystals are joined together to form a region having substantially no grain boundaries, i.e., a monodomain region which can substantially be regarded as a single crystal. A semiconductor device is formed by using the monodomain region as an active layer.

  • Patent number: 7372082
    Abstract: A submount substrate for mounting a light emitting device and a method of fabricating the same, wherein since a submount substrate for mouthing a light emitting device in which a Zener diode device is integrated can be fabricated by means of a silicon bulk micromachining process without using a diffusion mask, some steps of processes related to the diffusion mask can be eliminated to reduce the manufacturing costs, and wherein since a light emitting device can be flip-chip bonded directly to a submount substrate for a light emitting device in which a Zener diode device is integrated, a process of packaging the light emitting device and the voltage regulator device can be simplified.

  • Patent number: 7368772
    Abstract: The active pixel includes a photodiode, a transfer gate, and a reset transistor. The photodiode is substantially covered with an overlying structure, thus protecting the entire surface of the photodiode from damage. This substantially eliminates potential leakage current sources, which result in dark current. In one embodiment, the photodiode is covered by a FOX region in combination with the transfer gate.

  • Patent number: 7365376
    Abstract: A semiconductor integrated circuit effectively makes use of wiring channels of wiring formed by a damascene method. When first cells are used, since the M1 power source lines are laid out at positions spaced away from a boundary between the cells, the power source lines are not combined in laying out a semiconductor integrated circuit. As a result, the width of the power source lines is not changed. Accordingly, an interval between the line and a line which is arranged close to the line, determined in response to a line width of the lines, can satisfy a design rule; and, hence, the reduction of the wiring channels can be obviated, whereby the supply rate of the wiring channels can be enhanced, and, further, the integrity of a semiconductor chip can be enhanced.

  • Patent number: 7361942
    Abstract: A bi-directional transient voltage suppression (“TVS”) device (101) includes a semiconductor die (201) that has a first avalanche diode (103) in series with a first rectifier diode (104) connected cathode to cathode, electrically coupled in an anti-parallel configuration with a second avalanche diode (105) in series with a second rectifier diode (106) also connected cathode to cathode. All the diodes of the TVS device are on a single semiconductor substrate (301). The die has a low resistivity buried diffused layer (303) having a first conductivity type disposed between a semiconductor substrate (301) having the opposite conductivity type and a high resistivity epitaxial layer (305) having the first conductivity type. The buried diffused layer shunts most of a transient current away from a portion of the epitaxial layer between the first avalanche diode and the first rectifier diode, thereby reducing the clamping voltage relative to the breakdown voltage.

  • Patent number: 7358603
    Abstract: A high-density electrical package utilizing an array of high performance demountable electrical contacts such as UEC, T-Spring, F-Spring and their equivalent contained in a carrier in the form of an interposer between one or more components and a substrate. The carrier is made of a thermally conductive metal or contains thermally conductive metal to provide heat-spreading or dissipation functions in addition to the function of the retention and alignment of the electrical contacts. The above interposer is used for chip attach for a single chip or a stack of chips in the package. The interposer provides electrical connections through individual electrical contact to another chip or to the substrate of the package. It provides also the heat spreading or dissipation function to the chips connected thermally to a particular interposer. The interposer can further be connected thermally to an external heat spreader when necessary.
