摘要： A method of manufacturing an active matrix LCD is disclosed whereby gate bus lines, gate electrodes and source bus line segments are patterned from the same vacuum deposited first metal layer. An insulating layer, semiconductor layer, extrinsic semiconductor layer and second metal layer are then successively deposited on the substrate. A TFT channel region is formed by etching each of these layers in a second patterning process. During this step, storage capacitors may be formed by patterning the second metal layer so that it overlaps part of the gate bus lines. A transparent conductive layer is next deposited on the substrate. Pixel electrodes are then formed by patterning the transparent conductive layer in a third patterning process. Further, using a portion of the transparent conductive layer as a mask, the second metal layer and part of the extrinsic semiconductor layer are etched to form source and drain electrodes. Additionally, the transparent conductive layer can be patterned to provide an electrical connection between adjacent bus line segments to form a plurality of electrically continuous source bus lines.
摘要翻译：公开了一种制造有源矩阵LCD的方法，其中栅极总线，栅电极和源极总线段被从相同的真空沉积的第一金属层图案化。然后将绝缘层，半导体层，非本征半导体层和第二金属层依次沉积在基板上。通过在第二图案化工艺中蚀刻这些层中的每一层来形成TFT沟道区。在该步骤期间，可以通过对第二金属层进行图案化以使其与栅极总线的一部分重叠而形成存储电容器。接着在衬底上沉积透明导电层。然后通过在第三图案化工艺中图案化透明导电层来形成像素电极。此外，使用透明导电层的一部分作为掩模，蚀刻第二金属层和非本征半导体层的一部分以形成源极和漏极。另外，透明导电层可被图案化以在相邻的总线段之间提供电连接，以形成多个电连续的源极总线。
