Role Overview

We are seeking a Senior Process Engineer specialized in Photolithography to join our team in Singapore. This role involves operating and refining photolithography equipment, primarily the ASML i-Line Stepper Systems, by developing and optimizing process recipes such as focus, exposure dose, and alignment to ensure process stability and high yield.

Key Responsibilities

• Run and enhance photolithography processes, including routine monitoring, troubleshooting, tool qualification, SPC tracking, and defect analysis to maintain stable and reproducible results.
• Analyze process and measurement data for improvement opportunities, perform root-cause investigations, and execute corrective and preventive measures to boost yield, throughput, and process consistency.
• Support MEMS technology development by setting up and optimizing photolithography, screen printing, and bonding processes within semiconductor manufacturing.
• Maintain consistent process oversight and control, addressing issues as they arise with effective corrective actions.
• Document process parameters, experimentation, and outcomes thoroughly while preparing detailed technical reports and presentations for internal teams.
• Regularly update process documentation and standard operating procedures (SOPs).
• Collaborate closely with R&D, production, and quality assurance teams to ensure smooth integration of photolithography, screen printing, and bonding processes.
• Contribute actively in team meetings, providing problem-solving input and supporting shift engineers and technicians as needed.
• Engage in continuous improvement initiatives aimed at enhancing efficiency, yield, and quality; identify opportunities for process automation and implement solutions.

Qualifications and Skills

• Bachelor’s degree in Electrical & Electronics, Mechatronics, Physics/Applied Physics, Materials Science, Chemical, or Mechanical Engineering.
• Solid understanding of photolithography or bonding principles in semiconductor processes. Familiarity with EKRA printing and bonding is an advantage.
• Experience with data analysis and statistical process control (SPC).
• Practical hands-on experience with photolithography equipment such as Track (DNS/TEL), Steppers (Canon/ASML), Aligners (EVG/SUSS), as well as Screen Printing (EKRA) and Bonding (EVG) equipment is highly desirable.
• Strong communication skills and ability to effectively work within teams.
• Capability to work independently and manage multiple tasks efficiently.
