Senior Process Engineer, Defectivity - Defect Reduction Lead

PVH (Tommy Hilfiger/Calvin Klein); Singapore; On-site; SGD 120,000 - 180,000; Full time

Job summary

ASM in Singapore is seeking a Senior Process Engineer, Defectivity, to advance semiconductor manufacturing by reducing defectivity and driving process improvements across front-end wafer processing equipment.

You will apply DOE, statistical analysis and root-cause investigation to identify defect sources, collaborate with cross-functional teams, and validate long-term improvements to manufacturability and product quality.

Responsibilities

• Lead investigations into defectivity issues affecting front-end wafer processing equipment and manufacturing processes.
• Identify and resolve equipment-induced, process-induced, handling-induced, and material-induced defect mechanisms.
• Analyze defect signatures using defect maps, spatial distributions, wafer trends, process data, and manufacturing performance metrics.
• Apply structured problem-solving methodologies including DOE, statistical analysis, failure analysis, and root-cause investigation techniques.
• Drive corrective and preventive actions and validate long-term effectiveness through data-driven verification.
• Investigate contamination, particle generation, material interactions, mechanical sources, environmental influences, and wafer handling-related defects.
• Develop a deep understanding of defect generation mechanisms throughout wafer movement, process execution, metrology, inspection, and automation systems.
• Partner with engineering teams to improve defect performance, process robustness, equipment reliability, and manufacturability.
• Utilize advanced defect characterization and analytical techniques to determine defect origin, composition, transport mechanisms, and generation pathways.
• Establish defectivity reduction roadmaps and support technology development, qualification, and continuous improvement initiatives.
