A transparent conductive film substantially made from In.sub.2O.sub.3,
SnO.sub.2 and ZnO, having a molar ratio In/(In+Sn+Zn) of 0.65 to 0.8 and
also a molar ratio Sn/Zn of 1 or less: The transparent conductive film
has a favorable electric contact property with an electrode or line made
from Al or Al alloy film. Further, a semiconductor device having an
electrode or line made from the transparent conductive film has high
reliability and productivity.
