Abstract: A coil assembly (200) is described herein that comprises a) at least one coil (220) with a width (240); and b) at least one boss (210) coupled to the at least one coil, wherein the at least one boss comprises at least two support sections. Methods of forming and/or producing coil assemblies are described herein and comprise a) providing a coil; b) providing at least one boss having at least two support sections; and c) coupling the at least one boss to the coil.

Abstract: The invention includes coil constructions configured for utilization in PVD chambers, and also includes methods of forming coil constructions suitable for utilization in PVD chambers. The coil constructions can include one or more cup projections extending from an outer periphery of a coil body. The cup projections are one-piece with the coil body, and have a recess extending therein with a projecting lip extending entirely around the recess. The cup projections further comprise a fastener receiver within the recess configured to receive a fastener for connecting the coil with the chamber. The methods of forming the coil construction can include identifying separate components of an assembly associated with a coil replacement kit, and forming a one-piece construction which can be substituted for at least two of the components.
