Senior Process Engineer – Cleaning Processes

The Senior Process Engineer – Cleaning Processes is responsible for the development, optimization, qualification, and control of advanced cleaning processes used in glass panel semiconductor manufacturing.

The role focuses on achieving superior surface cleanliness, defect reduction, adhesion performance, and process stability for downstream metallization, lithography, and plating operations.

This position plays a critical role in establishing robust cleaning technologies for advanced packaging and glass substrate integration.

• Develop and optimize cleaning processes for glass substrate preparation, pre-clean before Laser treatment, and Litho pre-cleaning.
• Define and control critical process parameters, including chemistry concentration, temperature, immersion time, and drying conditions.
• Own and improve cleaning process performance with focus on defect reduction, surface cleanliness, and adhesion enhancement.
• Lead root cause analysis and corrective actions for particle contamination, residues, staining, corrosion, and delamination issues.
• Drive process qualification, DOE execution, and recipe optimization for new tools, materials, and chemistries.
• Work closely with wet chemistry and analytical teams to ensure bath stability, contamination control, and process consistency.
• Develop and maintain SOPs, process specifications, OCAPs, and process control documentation for manufacturing operations.
• Support pilot line and high-volume manufacturing ramp activities with emphasis on yield improvement and process robustness.
• Ensure compliance with EHS and chemical safety requirements while driving continuous improvement in chemical usage, cycle time, and manufacturing efficiency.
• Own equipment process qualification activities, including SAT, installation, operational, and performance qualifications, process acceptance, and production release for DFR developer and stripper tools.
• Collaborate with equipment engineering teams to improve wet bench capability, process stability, and equipment reliability.
