  • Publication number: 20050164480
    Abstract: The present invention is directed to methods for making electronic devices with a thin anisotropic conducting layer interface layer formed between a substrate and an active device layer that is preferably patterned conductive layer. The interface layer preferably provides Ohmic and/or rectifying contact between the active device layer and the substrate and preferably provides good adhesion of the active device layer to the substrate. The active device layer is preferably fashioned from a nanoparticle ink solution that is patterned using embossing methods or other suitable printing and/or imaging methods. The active device layer is preferably patterned into an array of gate structures suitable for the fabrication of thin film transistors and the like.

  • Publication number: 20050034504
    Abstract: The invention relates to a tool comprising a partial region made from plastic, in which a material with slide bearing properties is inlaid. Said tool is a moulding tool, which can be applied, for example, in the deep-drawing of metal pieces. The partial region in which the material with slide bearing properties, for example graphite, is inlaid, is a front layer (11) of the tool, comprising the moulding region thereof. The backing (12) of the tool is also made from plastic, which can optionally contain conventional fillers. The front layer (11) of the tool, reinforced, for example, with graphite, permits a deep drawing optionally without the use of lubricants, whereby the moulding region of the tool has good slide bearing properties and a high pressure resistance.

  • Publication number: 20050008880
    Abstract: Compositions, inks and methods for forming a patterned silicon-containing film and patterned structures including such a film. The composition generally includes (a) passivated semiconductor nanoparticles and (b) first and second cyclic Group IVA compounds in which the cyclic species predominantly contains Si and/or Ge atoms. The ink generally includes the composition and a solvent in which the composition is soluble. The method generally includes the steps of (1) printing the composition or ink on a substrate to form a pattern, and (2) curing the patterned composition or ink. In an alternative embodiment, the method includes the steps of (i) curing either a semiconductor nanoparticle composition or at least one cyclic Group IVA compound to form a thin film, (ii) coating the thin film with the other, and (iii) curing the coated thin film to form a semiconducting thin film.

  • Patent number: 6704514
    Abstract: The invention concerns a method of establishing and/or maintaining a wake mode in an electrical installation, which in addition to at least one receiving device has at least one transmitting device that is connected through an optical bus system. So as not to always have to operate the different devices in the stand-by mode when no data traffic takes place through the optical bus system, the state of the art proposes activating the receiving device only part of the time. If during that time the receiving device receives a corresponding signal from the transmitting device, the stand-by mode is ended in order to establish the data exchange. However this operating mode is also disadvantageous because of the power consumption.
