Abstract
A method for forming a conductive layer is disclosed, which has the following steps. First, a substrate is provided, and then a patterned photoresist layer having an undercut is formed on the substrate. After that, at least one conductive layer is deposited on the substrate. Finally, the patterned photoresist layer is lifted off; wherein the shape of the conductive layer remaining on the substrate is complementary to that of the patterned photoresist layer.
