  • Publication number: 20100065529
    Abstract: A method of etching a foil for use in an electrolytic capacitor utilizes a nanoimprinted optic to control the etch pattern. The optic is formed by creating a self-assembled monolayer (SAM) of hemispheres onto the surface of an optical quartz substrate. A laser is directed onto the optic while the foil underlies the optic, and the concentrated light source is used to effectively image an array of submicron spots. The resulting spots allow for controlled initiation of etch tunnels during a subsequent electrochemical etch of the foil, with the purpose of ultimately increasing foil capacitance through the increased surface area.

  • Patent number: 6784761
    Abstract: A thermal transfer sheet is equipped with an approval information of being approved as applicable to the predetermined printer. The thermal transfer sheet is set on a printer and, when a determinator determines that the approval information is correct for the printer, the printer is interlocked with the determinator to work the printer in the state where the thermal transfer sheet is set thereon. In the particularly preferable aspect, a recording part of thermal transfer are worked together with the printer and an approval information is destructed by the heating. A mark of an approval information can be formed of a material which can be detected by the light in a visible light region or an invisible region light, a magnetic material, an electrically-conductive material or a resonance circuit. The resonance circuit is preferably formed by thermally transferring an electrically-conductive layer in a predetermined pattern.

  • Patent number: 6780337
    Abstract: The invention relates to a method for trench etching, in particular a method for anisotropic deep trench (DT) etching in an Si substrate by plasma dry etching, such as reactive ion etching (RIE), magnetically enhanced RIE or inductively coupled plasma etching (ICP), and sidewall passivation of the etched trenches in the Si substrate, the Si substrate being provided with an etching mask before the beginning of the etching operation. The invention is intended to provide a method for depth etching which, with a low outlay, makes it possible to achieve a significantly larger etching depth at higher speed and which enables a further reduction of the structure widths without any difficulty.

  • Patent number: 6763265
    Abstract: In one aspect, a method of manufacturing a capacitor includes disposing one or more conductive layers of a first electrode stack in a recess of an alignment mechanism, where the recess is positioned relative to two or more alignment elements. The method further includes placing a separator over the one or more conductive layers where an outer edge of the separator contacts the two or more alignment elements. In one embodiment, a capacitor includes anode and cathode foils having offsetting edge portions. In one embodiment, a multiple tab cathode for a flat capacitor. A plurality of cathode tabs are portioned into a plurality of cathode tab groups positioned in different locations along the edge of the capacitor stack to reduce the amount of space required for connecting and routing the cathode tabs.

  • Publication number: 20040130853
    Abstract: A metal collector foil for an electric double layer capacitor has etched upper and lower surface layers and an unetched central layer disposed between the etched upper and lower surface layers. The etched upper and lower surface layers have a total thickness sufficient to provide the metal collector foil with a capacitance per unit area that corresponds to a capacitance value obtained when the etched metal collector foil is subjected to an anodic formation process with application of a withstanding voltage of 65.6 volts, the capacitance value being not less than 1.7 &mgr;F/cm2. The unetched central layer has a thickness sufficient to provide the metal collector foil with a tensile strength not less than 9,000 N/cm2. A method of producing the metal collector foil and an electric double layer capacitor incorporating therein the metal collector foil are also disclosed.

  • Patent number: 6682658
    Abstract: A pixel electrode employs a transparent electrode made from indium-zinc-oxide (IZO) that is capable of preventing damage and bending thereof. In a liquid crystal display device containing pixel electrodes, the transparent electrode is made from indium-zinc-oxide (IZO) having an amorphous structure so that it can be etched within a short period of time with a low concentration of etchant. Accordingly, it is possible to prevent damage and bending of the transparent electrode upon the patterning thereof.

  • Patent number: 6565759
    Abstract: A method for etching a pattern within a silicon containing dielectric layer upon a substrate employed within a microelectronics fabrication, employing a plasma activated reactive gas mixture, with layer material etch rate, etch rate ratio and pattern aspect ratio controlled by controlling the gas composition. There is provided a silicon substrate formed upon it a patterned microelectronics layer over which is formed a silicon containing dielectric layer. There is placed the silicon substrate within a reactor chamber equipped with electrodes which is evacuated. There is then filled the reactor chamber with a reactive gas mixture consisting of an oxidizing gas and two reactive gases. There may be optionally included in the reactive gas mixture nitrogen and inert gases for control purposes, but excluded from the reactive gas mixture are oxidizing gases containing carbon and oxygen.

  • Patent number: RE38049
    Abstract: An existing stacked capacitor fabrication process is modified to construct a three-dimensional stacked container capacitor. The present invention develops the container capacitor by etching an opening (or contact opening) into a low etch rate oxide. The contact opening is used as a form for deposited polysilicon that conforms to the sides of the opening walls. Within the thin poly lining of the oxide container a high etch-rate oxide, such as ozone TEOS, is deposited over the entire structure thereby bridging across the top of the oxide container. The high etch-rate oxide is planarized back to the thin poly and the resulting exposed poly is then removed to separate neighboring containers. The two oxides, having different etch rates, are then etched thereby leaving a free-standing poly container cell with 100% (or all) of the higher etch rate oxide removed and a pre-determined oxide surrounding the container still intact.
