ABSTRACT:
A continuously variable multi-position magnetron that is rotated about a central axis in back of a sputtering target at a freely selected radius. The position is dynamically controlled from the outside, for example, through a hydraulic actuator connected between a pivoting arm supporting the magnetron and an arm fixed to the shaft, by two coaxial shafts independent controllable from the outside and supporting the magnetron through a frog-leg mechanism, or a cable connected between the pivoting arms and moved by an external slider. The magnetron can be rotated at two, three, or more discrete radii or be moved in a continuous spiral pattern.
