  • Patent number: 6333546
    Abstract: An electrically activated fuse with a high melting point heater element in series with a low melting point fusible link. The heater element has a higher resistivity and larger cross-sectional area than the fusible link in order to withstand heat that the heater element generates bringing the fusible link to its melting point. Fuse dimensions (width and length) are each between 0.1 and 2.0 microns, with a thermal mass of the heater element being sufficient to melt the fusible link.
    Type: Grant

  • Patent number: 6246583
    Abstract: An apparatus and method are provided that remove sufficient heat from both SOI and non-SOI semiconductor devices to prevent the devices from overheating during operation. A plurality of thermally conductive pads such as electrically conductive studs are coupled to a first side of a semiconductor device having circuit elements formed thereon. The thermally conductive pads also are coupled to a substrate comprising an apparatus for extracting heat from the thermally conductive pads. The apparatus for extracting heat from the thermally conductive pads preferably comprises one or more metallic planes. A module cover having a thermally conductive path formed therein also may be coupled between the apparatus for extracting heat and a heat sink to further aid in heat removal from the semiconductor device. Thermally conductive pads may be coupled between the semiconductor device and I/O pins of the substrate to improve heat dissipation via the I/O pins.

  • Patent number: 6190836
    Abstract: A method of repairing defects on masks includes the step of providing a coating on the mask to prevent damage to clear regions of the mask from laser ablation splatter, laser ablation caused quartz pitting, laser deposition staining, and FIB caused gallium staining. The coating is a metal, a polymer, or a carbon material. The coating is formed on clear regions of the mask as well as either over or under the light absorbing material of the mask. A coating comprising a thin copper layer significantly improves imaging with the ion beam while protecting clear regions of the mask from FIB stain. A coating formed of a photosensitive polymer is used to etch opaque defects. While wanted opaque regions adjacent an opaque defect are also etched in this etch step, these created clear defects are then repaired in a subsequent FIB deposition step while a copper coating protects adjacent clear regions from FIB stain.

  • Patent number: 5872025
    Abstract: Stacked three-dimensional devices can be prepared by stacking wafers as an alternative to stacking individual devices. Chip regions are formed on several wafers with each chip region being surrounded by a separation region, such as an insulator filled trench. The wafers are then stacked with the chip regions in alignment. Aligning the wafers can be facilitated using notched regions in the periphery of the wafers. The wafers are then joined together by lamination. After laminating the stacks of wafers, stacks of chips are separated by etching, dicing or other processes, which separate out stacked chip devices from the stacked wafer at the chip separation regions. The process allows several stacked chip devices to be manufactured simultaneously.

  • Patent number: 4386729
    Abstract: An octagonal container having a unique bottom closure and a blank therefor are provided. The body of the octagonal container includes a pair of major wall panels, a pair of minor wall panels, and four corner wall panels. Each major and minor wall panel is foldably connected to a corner wall panel on either side. In the preferred embodiment, one of the minor wall panels is formed from two pieces, which are secured in overlapping relation to one another. The closure section includes a pair of rectangular major cover flaps, a pair of rectangular minor cover flaps, and four polygonal corner flaps. Each major cover flap is foldably connected to a major wall panel. Each corner flap is foldably connected to a corner wall panel. Each minor cover flap is foldably connected to a minor wall panel. In the preferred embodiment, one of the minor cover flaps is formed from two pieces, which are fastened in overlapping relation to one another.
