An active matrix liquid crystal display device, with a plurality of thin-film transistors provided over a glass substrate each including an anodized oxide film of aluminum gate electrode, in which transparent pixel electrodes are formed in the same plane as the gate electrodes between the glass substrate and amorphous silicon islands over which source and drain electrodes are provided.
摘要:
In a first manufacturing step of an active matrix liquid-crystal panel, a transparent conductor film and a metal film are sequentially accumulated on a substrate in this order so as to form a two-layer film. The two-layer film including the transparent conductor film and the metal film is subjected to photoetching to simultaneously form at least a pixel electrode (transparent conductor film) and a gate electrode (metal film) of a thin-film transistor according to a predetermined pattern. In a fabrication process near the end of the fabrication, when the source and drain electrodes of the thin-film transistors are formed, the metal film on the pixel electrode is simultaneously removed. Since the removal of the metal film protecting the pixel electrode is simultaneously achieved at a point near the final process, protection of the pixel electrode is guaranteed, thereby realizing improvement of the yielding and reduction of the production process.

In a photosensor having a metal electrode, at least one photoelectric conversion layer which overlies the metal electrode, and a transparent or partly transparent conductive layer which overlies the photoelectric conversion layer, a recombination layer for recombining electrons and holes is disposed between the metal electrode and the photoelectric conversion layer. By disposing the recombination layer, the metal electrode having an insulating oxide film on its surface can be handled as if the insulating oxide film were not existent. The dark current is suppressed, and the photo-response is made good. As the materials of the recombination layer, Sb.sub.2 S.sub.3, As.sub.2 Se.sub.3, As.sub.2 S.sub.3, Sb.sub.2 Se.sub.3 etc. are typical.

In a calibration method a ring-shaped jig is disposed on a machine tool workpiece. The optical axis of a camera is aligned parallel to an axis of the machine tool. The jig is photographed with the horizontal or the vertical direction of the camera aligned with an axial direction other than the signal direction of the machine tool. The circumferential shape of the jig in the photograph is extracted as a contour. The center position of the jig in the image is calculated from the contour while all distortion correction coefficients in tangential and radial directions are ignored and set to zero. The displacements of the main point of the camera are set to zero. The translation distance, which is an external parameter of calibration, is calculated based on the center position of the jig in the image and the known three-dimensional center position of the jig.
