METHOD OF FABRICATING CONDUCTIVE LAYER
摘要:
A method of fabricating a patterned conductive layer is provided. First, a conductive layer whose material includes at least aluminum-copper (Al—Cu) alloy is formed on a substrate. Then, a heat treatment process is performed to heat the conductive layer to a temperature higher than the phase change temperature of the Al—Cu alloy. Next, the conductive layer is patterned. The method in the present invention can avoid the formation of metallic educt and facilitate subsequent etching processes.
