Engineer – Defectivity (Semiconductor)

About The Business Tata Electronics Private Limited (TEPL) is a greenfield venture of the Tata Group with expertise in manufacturing precision components. Tata Electronics (a wholly owned subsidiary of Tata Sons Pvt. Ltd.) is building India’s first AI-enabled state-of-the-art Semiconductor Foundry. This facility will produce chips for applications such as power management IC, display drivers, microcontrollers (MCU) and high-performance computing logic, addressing the growing demand in markets such as automotive, computing and data storage, wireless communications and artificial intelligence. Tata Electronics is a subsidiary of the Tata group. The Tata Group operates in more than 100 countries across six continents, with the mission 'To improve the quality of life of the communities we serve globally, through long term stakeholder value creation based on leadership with Trust.’Responsibilities Own inlinedefect density performance(e.g., particles/defects per wafer or per cm²) and drive reductions to meet yield, quality, and customer targets. Operate and optimizedefect inspectionacross tools (optical brightfield/darkfield, patterned wafer inspection) including recipe tuning, nuisance reduction, and tool-to-tool matching. Define and executedefect monitoring strategy : Lot/monitor wafer plan, inspection points (pre/post critical steps), sampling rates, and sensitivity/recipe settings. Performdefect disposition and classification : nuisance vs real defects, systematic vs random; maintain defect library and automate classification where applicable. Leaddefect excursion management : rapid detection, lot containment (hold/quarantine), risk assessment, and communication with Production/QA/Yield. Driveadder controlby step/tool/module: quantify adders (after–before), identify top contributing tools/recipes/chambers, and lead corrective actions. Executeroot-cause analysis (RCA)using defect maps, signature analysis, cluster/hotspot detection, equipment logs, PM history, chemical/consumable lots, and wafer transport/FOUP history Coordinatedefect review and failure analysis : SEM review, EDS, FIB cross-section requests; correlate physical defects to electrical impact with Yield/Product teams. Own defect density and D0 performance; quantify defect-to-yield loss using kill ratio, CP/WAT correlation, and yield loss prediction models. Lead DSA and manage the defect library/classification (real vs nuisance); drive nuisance filtering and review/BKM standardization. Develop and optimize inspection recipes (sensitivity/threshold/care-area), tool matching, and post-PM qualification to control adders and excursions. Drive defect reduction CIP: Pareto top contributors, RCA with module/equipment/CFM/yield teams, and implement CAPA for sustained improvement Support new inspection tool installs, tech transfer, and ramp by completing tool qualification and production release, defining acceptance criteria, and ensuring sustainable capacity and uptime. Mentor more Engineers as required Travel, as necessary Presentation to internal teams and senior executives Drive cross-functional yield improvement projects and DOEs Apply structured problem-solving and risk tools: FMEA, 8D, and strong RCA to drive effective corrective action and prevent recurrence Ensure inspection measurement capability/accuracy via basic MSA/GR&R and tool-to-tool correlation Use SPC, FDC, and APC to monitor process health, detect excursions early, and enable data-driven defect/yield controlEssential Attributes Able to work independently, self-motivated with a strong drive to win.
