Additionally, you will be the day-to-day link between OEMs, development, operations, quality, equipment, and suppliers, moving new recipes, tools, and process changes from trial to stable production with clear documentation, yield targets, and a schedule. Define process windows (pull rate, rotation, hot zone, slurry or diamond wire, tension, coolant, clean chemistry) and track KPIs such as kg/pull, wafer yield, kerf loss, downtime, scrap, and first-pass yield.
