Abstract:
A polycrystalline aluminum thin film is made of polycrystals of an alloy of aluminum. The polycrystalline aluminum thin film includes a first additive which is distributed with even concentration over an inside of each crystal grain and an interface of the crystal grain and a second additive which is distributed with higher concentration in the interface of the crystal grain than in the inside of the crystal grain.
