Abstract
The present invention relates to a method for manufacturing a TAB tap. The method includes forming a circuit pattern region having input/output terminal pattern on a base film, and forming an exposing region at a convey region having a sprocket hole for exposing the base film. Accordingly, the present invention provides a TAB tape that improves reliability of a product by fundamentally preventing the generation of metal particles by forming exposing regions that expose a base film through selectively etching and removing a metal layer of a convey region formed at both side of a TAB tape and having a sprocket hole, and that prevents short-circuit by partially removing a base film at a predetermined region not having a circuit pattern formed thereon through etching.
