Abstract

An ion beam sputtering target assembly has six sputter targets arranged in pairs on three paddles and disposed upon the circumference of a circular holder. The circular holder can be rotated about its axis in such a way as to bring any one of the target pairs to be exposed to the sputtering ion beam to deposit a film on substrate. The paddle is rotated to bring a desired target in the pair into position for sputtering. An alternative embodiment is provided with an enlarged region which allows one of the target paddles to be rotated about its axis while that target paddle is in an inactive, non-sputtering rotary position.
