Abstract
In those conventional arts, for large-size LCD, the process of copper damascene interconnect has some problems of forming a uneven copper seed layer and forming hollows during electrical plating due to the electrical plating area being too large to electroplate uniformly. In this invention, it employs a Cu tape to directly stick on a substrate to replace forming a copper seed layer and electroplating. Hence, the invention avoids the problem of unevenness and hollows in those conventional arts and so the Cu lines can be applied to the large-size LCD.
