| 简介 |
PROBLEM TO BE SOLVED : To provide an Al alloy film, that, in a production process of a thin-film transistor substrate, reflective film, reflective anode electrode, touch panel sensor, or the like, can effectively prevent corrosion such as corrosion on an Al alloy surface when immersed in a sodium chloride solution and pinhole corrosion (black dots), thereby having excellent corrosion resistance, and also can prevent hillock formation, thereby also having excellent heat resistance.
SOLUTION : An Al alloy thin film of the present invention is used for a wiring film or a reflective film on a substrate, and contains 0.01 to 0.5 atom% of Ta and/or Ti and 0.05 to 2.0 atom% of a rare earth element.
