• Support end-to-end photolithography processes including; Coat, Expose and Develop process using tools like ACM and Delta tools, Pattern Lamination, Expose and Develop process, After Develop Inspection (ADI) and CD metrology
• Monitor and control critical parameters; Resist thickness uniformity, Critical Dimension (CD), Overlay / alignment accuracy and Defects (particles, scum, residues, lifting)
• Drive defect reduction and cycle time improvement projects
• Perform routine data analysis and trend monitoring
• Support root cause analysis (RCA) and implement corrective actions
• Support process development and optimization activities.
• Coordinate with Equipment Engineering for needed tool calibration, preventive maintenance and tool qualification.
• Support new product introduction (NPI) activities; Recipe setup and validation and process qualification
• Assist in developing process capability for new technologies
• Prepare and maintain Work instructions (WI), Process specifications and recipes, Engineering change documents

Requirements

• Minimum diploma in Electronics Engineering, Electrical Engineering, Mechatronics, Industrial Technology, or related field (Engineering Degree)
• Exposure to WLCSP, or semiconductor processes
• Experience as a former Nepes Process Technician or Engineer is an advantage, particularly with background and knowledge in the Photolithography process.
• Familiarity with Photoresists (positive/negative tone) and Lithography defect mechanisms
• Knowledge of DOE and SPC tools (JMP, Minitab, Excel, Infinity QS)
• Strong analytical and troubleshooting skills
• Detail-oriented and methodical approach
• Good communication and teamwork
• Proactive and willing to learn in a high-tech manufacturing environment
• Cleanroom environment (strict contamination control)
• Handling of chemicals (photoresist, developer, solvents)
• Shift work may be required to support production
