  • Publication number: 20250125161
    Abstract: Some implementations described herein provide an etch tool having a nozzle component. The nozzle component (e.g., a gas injector component) includes a spinel-based composite material that has an increased resistivity to damage and/or debris generation within the etch tool during a plasma-based etch operation that etches material from a semiconductor substrate. The increased resistivity may decrease contamination within the etch tool to increase a yield of integrated circuit devices on the semiconductor substrate relative to another semiconductor substrate that is etched using another etch tool having another nozzle component of another material.
