Popis: The facing targets sputtering (FTS) system, typical of plasma-free sputtering systems, was used to deposit aluminum thin films composed of very fine grains with a smooth surface, large hardness and low resistivity. When the argon gas pressure P Ar was also low as 10 −1 Pa, the aluminum films deposited at a bias voltage to substrate V b of −40 V became smoother, more reflective and harder. The films deposited at a V b of −100 ∼−160 V revealed a definite (111) orientation of the aluminum crystallites parallel to the film plane. The resistivity ϱ of the films deposited at a P Ar below 10− Pa was almost equal to that of bulk aluminum.
