SHUTTER DISC FOR A SEMICONDUCTOR PROCESSING TOOL
Some implementations described herein provide a shutter disc for use during a conditioning process within a processing chamber of a deposition tool. The shutter disc described herein includes a material having a wave-shaped section to reduce heat transfer to the shutter disc and to provide relief from thermal stresses. Furthermore, the shutter disc includes a deposition of a thin-film material on a backside of the shutter disc, where a diameter of the shutter disc causes a spacing between an inner edge of the thin-film material and an outer edge of a substrate support component. The spacing prevents an accumulation of material between the thin film material and the substrate support component, reduces tilting of the shutter disc due to a placement error, and reduces heat transfer to the shutter disc.
