The present invention is directed to thin film transistors using nanowires (or other nanostructures such as nanoribbons, nanotubes and the like) incorporated in and / or disposed proximal to conductive polymer layer(s), and production scalable methods to produce such transistors. In particular, a composite material comprising a conductive polymeric material such as polyaniline (PANI) or polypyrrole (PPY) and one or more nanowires incorporated therein is disclosed. Several nanowire-TFT fabrication methods are also provided which in one exemplary embodiment includes providing a device substrate; depositing a first conductive polymer material layer on the device substrate; defining one or more gate contact regions in the conductive polymer layer; depositing a plurality of nanowires over the conductive polymer layer at a sufficient density of nanowires to achieve an operational current level; depositing a second conductive polymer material layer on the plurality of nanowires; and forming source and drain contact regions in the second conductive polymer material layer to thereby provide electrical connectivity to the plurality of nanowires, whereby the nanowires form a channel having a length between respective ones of the source and drain regions.

A plastic package for an image sensor or other electronic component which comprises a plastic body, preferably of LCP material, molded around a leadframe and defining a cavity in which the image sensor is to be disposed. A lid assembly is provided having a transparent glass lid retained in a plastic lid frame which is weldable or otherwise bondable to the plastic body of the package to enclose the image sensor mounted in the cavity. The leadframe is usually composed of copper or a copper alloy, or a ferrous alloy having a copper coating. An interfacial layer is formed on the surfaces of the leadframe at least in those portions which are in contact with the plastic body which serves to provide substantially improved adhesion between the leadframe and the plastic material to achieve a hermetic bond between the metal and plastic materials. The interfacial layer is composed of a cuprous oxide base layer formed on a surface of the leadframe, and a cupric oxide layer formed on the cuprous oxide layer. The cupric oxide outer layer has an acicular structure which provides an interlocking mechanism for adhesion to the plastic material molded thereto in forming the package.

The invention discloses a flexible film type solid state super capacitor and a method for manufacturing the same; the flexible film type solid state super capacitor comprises a positive electrode, a negative electrode, an outer electrode and an encapsulation film, wherein a flexibility solid state electrolyte membrane is arranged between the positive and the negative electrodes. The manufacturingmethod is as follows: the outer electrode pasting, the electrode pasting, the flexibility solid state electrolyte pasting, the electrode pasting, the outer electrode pasting and the encapsulation pasting are orderly and precisely coated on a basal body by the printing technique; by fitting the corresponding pressing, drying, cutting and packaging techniques, the flexible film type solid state super capacitor with electrode-membrane-electrode structure is finally formed. The flexible film type solid state super capacitor has the advantages of low product internal resistance and good power characteristic, and is suitable for the large scale production and particularly applied to flexible electric products such as electric papers, intelligent name cards and plastics electric products, etc.
