    Abstract: A thin film transistor (TFT) liquid crystal display (LCD) comprises a plurality of image pixels demarcated between an overlying liquid crystal display layer and an underlying glass substrate. Each image pixel comprises a dedicated top-gate TFT disposed over the glass substrate. Each top-gate thin film transistor comprises a process sensitive semiconductor layer disposed over the glass substrate, and a source electrode and a drain electrode disposed over the process sensitive semiconductor layer. The process sensitive semiconductor layer forms a process sensitive semiconductor active layer between the source electrode and the drain electrode and an active layer protection film is disposed over the process sensitive semiconductor active layer. A gate dielectric layer is disposed over the active layer protection film between the source electrode and the drain electrode and a gate electrode is disposed over the gate dielectric layer.

    Abstract: An electrical component package includes a glass substrate, an interposer panel positioned on the glass substrate, the interposer panel comprising a device cavity, a wafer positioned on the interposer panel such that the device cavity is enclosed by the glass substrate, the interposer panel, and the wafer. The electrical component package further includes a metal seed layer disposed between the interposer panel and the wafer, and a dielectric coating. The dielectric coating hermetically seals the interposer panel to the glass substrate, the interposer panel to the metal seed layer and the wafer, and the interposer panel hermetically seals the metal seed layer to the glass substrate such that the device cavity is hermetically sealed from ambient atmosphere.

    Abstract: An invention disclosure discloses a composite structure. The composite structure includes a substrate layer (120), a conductive layer (140) and an overlayer (160). The substrate has a first face (124) and a second face (122). The conductive layer has a first face (148) and a second face (149). The first face of the conductive layer is disposed on the at least a part of the second face of the substrate layer. A portion (144) of the conductive layer has a resistivity at least about ten times higher than an adjacent region (146) on the conductive layer. The overlayer may have a first face (162) and a second face (166). The first face of the overlayer is disposed on at least a part of the second face of the conductive layer such that the conductive layer is disposed between the overlayer and the substrate layer. The substrate layer comprises a material that is optically transparent over at least a part of the electromagnetic spectrum from about 180 nm to about 20 μm. The conductive layer comprises a layer having a thickness of about 10 nm or greater and having a resistivity of about 10 Ohm-cm or less. The conductive layer comprises a material that may be optically translucent or opaque over at least a part of the electromagnetic spectrum from about 180 nm to about 20 μm.
