Patent ID: 7374648

Claim:
A coil construction configured for utilization in a physical vapor deposition system, comprising: an annular coil body having an inner periphery and an opposing outer periphery; a plurality of electrically conductive bosses extending from the outer periphery of the annular coil body; a shield surrounding the annular coil, the shield having a first side facing the annular coil and an opposing second side, the first and second sides being separated by a shield thickness; and a plurality of support assemblies, each support assembly being disposed proximate the shield and the annular coil and being associated with one electrically conductive boss, each support assembly comprising: a first insulator spanning the shield thickness; and a second insulator contacting the first insulator and contacting the associated electrically conductive boss, the second insulator extending from the first side of the shield to the electrically conductive boss.
