TARGET ASSEMBLY

摘要

A target assembly includes a base comprising a first surface and a second surface opposite to the first surface. The base defining a threaded hole; a magnetron mounted on a first surface; a target movably mounted to the second surface, the target defining an opening corresponding to the threaded hole, the opening including a first end and a second end; and a screw. The screw can slide in the opening from the first end to the second end so the position between magnetron and the target is adjusted to adjust the bombarded area of the target.
