    摘要: A thin-film transistor panel is constituted by forming, on an insulating substrate, a plurality of thin-film transistors, a plurality of gate lines for each connecting gate electrodes of the thin-film transistors, and a plurality of pixel electrodes formed of a transparent conductive film connected to the thin-film transistors, then forming a low-resistance metal film of an Al or Al alloy for a data line and a surface metal film of Cr with a high density, forming a photoresist film of a predetermined pattern on the surface metal film, and etching the data line metal film and surface metal film. Then, the surface metal film remaining on the data line metal film is eliminated.

    摘要: A thin-film transistor includes a gate electrode and a semiconductor film consisting of amorphous silicon, formed on an insulating substrate to oppose each other through a gate insulating film, ohmic contact layers composed of n-type amorphous silicon doped with an impurity, electrically insulated from each other on the semiconductor film, and electrically connected to the semiconductor film, and source and drain electrodes arranged on the semiconductor film with a predetermined gap to form a channel portion, and electrically connected to the semiconductor film through the ohmic contact layers. The gate electrode and a portion surrounding the gate electrode are entirely formed into a continuous metal oxide film by a chemical reaction.

    摘要: A memory element is formed of a thin film transistor. The thin film transistor has a semiconductor layer, a source electrode electrically connected to the semiconductor layer, a drain electrode electrically connected to the semiconductor layer and formed separately from the source electrode, a gate electrode for controlling formation of a channel of the semiconductor layer, and a gate insulation film for isolating the gate electrode and the semiconductor layer from each other and causing a hysteresis in the relation between the drain current and the gate circuit. The insulation film is a silicon nitride film whose composition ratio of silicon to nitrogen is in a range of approx. 0.85 to 1.1. According to this invention, the relation between the gate voltage and the drain current can be set to have a hysteresis. Therefore, the thin film transistor can be used as a memory element. Further, according to this invention, data can be written, erased and read out by selectively applying an electric field to the gate insulation film. Therefore, the thin film transistor can be used as a memory element.

    摘要: A TFT panel is manufactured by a process of forming an oxide voltage-apply lines, gate lines, and capacitor lines on an insulating substrate, and a process of forming thin-film transistors, pixel electrodes, data lines, and ground lines. In a state that one end of the gate line and both ends of the capacitor line are connected to the oxide voltage-apply line, oxide films are formed on the surfaces of the gate line and the capacitor line by anodization. After forming the oxide film, the gate line and the capacitor line are electrically separated from the oxide voltage-apply line.

In the fourth step, the substrate is kept heated within the temperature range of 230.degree. C. to 270.degree. C., and the high-frequency power is controlled to be supplied so that an RF discharge power density falls within the range of 60 to 100 mW/cm.sup.2.
