摘要:
A self-aligned TFT array for liquid crystal display devices and a method of manufacturing the array are disclosed. A protective insulating layer on a semiconductor layer is exactly aligned with a gate electrode. A self-alignment method is used for patterning the protective insulating layer and an impurity-doped semiconductor layer on the semiconductor layer. No lift-off process is necessary.
