  • Publication number: 20230360944
    Abstract: Some implementations described herein provide a deposition tool that includes a grounding component between an edge ring of a substrate stage and a pumping plate component. The grounding component includes a grounding strap having a deformation region. The deformation region includes a recessed edge to reduce a likelihood of the grounding strap rubbing against a surface of the pumping plate component during operation of the deposition tool. Material properties of the grounding strap may reduce a likelihood of plastic deformation of the grounding strap during repeated cycling. In this way, an amount of particulates dislodged from the surface of the pumping plate component may be decreased to improve a yield of semiconductor product fabricated using the deposition tool. Furthermore, a frequency of servicing the grounding component may be decreased to decrease a downtime of the deposition tool and increase a throughput of semiconductor product fabricated using the deposition tool.
