  • Method for manufacturing thin film transistor substrate
    Publication number: 20070020836
    Abstract: A method for manufacturing a TFT substrate includes forming a gate metal layer on an insulating substrate, forming a photo-sensitive layer pattern on the gate metal layer, forming a gate wiring by etching the gate metal layer using the photo-sensitive layer pattern, exposing the gate wiring by stripping the photo-sensitive layer pattern, and washing exposed gate wiring with a washing agent containing nitric acid. Thus, the present invention provides a method for manufacturing a TFT substrate to improve the quality of the thin metal layer by removing particles effectively.
