Slicing process Engineering - Wafer

Role & responsibilities

Preferred candidate profile

Role & responsibilities:

• Monitor and control Diamond Wire Slicing processes to ensure consistent production of silicon wafers meeting thickness, TTV, bow, warp, and surface quality specifications.

• Analyze process performance data and identify opportunities for yield improvement, productivity enhancement, wire consumption reduction, and cost optimization.

• Support process optimization initiatives through experimentation, data analysis, and implementation of process improvements.

• Investigate and troubleshoot process abnormalities such as wafer breakage, wire marks, thickness variation, edge chipping, excessive kerf loss, and equipment-related issues.

• Collaborate with Production, Quality, Maintenance, and R&D teams to resolve process challenges and implement new technologies or process upgrades.

• Monitor key process parameters including wire speed, feed rate, tension, coolant/slurry parameters, slicing time, and consumable usage to ensure process stability.

• Conduct root cause analysis (RCA) and implement corrective and preventive actions (CAPA) for process deviations and quality issues.

• Develop, update, and maintain process documentation, including SOPs, Work Instructions, Control Plans, Process Flow Diagrams, and troubleshooting guides.

• Support process validation, qualification, and trial activities for new equipment, consumables, wire specifications, and process changes.

• Participate in continuous improvement projects focused on wafer quality improvement, cycle time reduction, OEE improvement, and manufacturing cost reduction.

• Monitor and improve process capability (Cp/Cpk) through Statistical Process Control (SPC) and data-driven process management.

• Ensure compliance with safety, environmental, quality, and operational standards in all slicing activities.

• Work closely with equipment engineers and maintenance teams to improve equipment reliability, uptime, and preventive maintenance effectiveness.

• Support operator training and skill development by providing technical guidance and process-related coaching.

• Prepare technical reports and present process performance metrics including yield, productivity, quality trends, consumable consumption, and improvement project results.
