In my current role at ZEISS, my responsibilities extend beyond routine equipment maintenance and on-duty support. My customer base shifted from back-end metrology to front-end manufacturing processes, where equipment requirements differ significantly. I am deeply involved in discussions with customers regarding tool improvement and development, while also coordinating closely with both customer sites and headquarters. This role requires a high level of engagement, precise manpower planning, and adaptability. Although this differs somewhat from my previous training in advanced packaging, the core principle remains unchanged: placing customer needs as the top priority.

• Responsible for photomask repair tools (MeRit, MG Neo); key customers include TSMC, PDMC, TMC, and TPC.
• Participated in the improvement and development of new equipment for customers (e.g., TSMC EBO, PDMC), acting as a communication bridge between customer sites and headquarters.
• Involved in new tool installation and acceptance processes (installation & qualification).
• Provided customer support across different regions.

As a Team Leader at Bruker, I was responsible for managing semiconductor-related products and services. My role included equipment maintenance, algorithm optimization, and customer relationship management. I successfully led multiple technical projects by coordinating team resources and providing technical guidance. Through continuous improvements in service quality and technical support, I helped secure long-term customer contracts(three-year) , significantly enhancing both company performance and customer satisfaction.

• Supervised machine maintenance and executed technical upgrades to ensure industry-leading performance.
• Led optimization of product algorithms, improving detection accuracy and operational efficiency.
• Built and maintained long-term customer relationships by delivering reliable technical support.
• Coordinated cross-functional teams to ensure smooth project execution and effective problem resolution.

At the Pesticide Testing Center, I worked as an Engineer responsible for operating analytical instruments and supporting pesticide testing and quality control. This role strengthened my hands-on technical skills and reinforced the importance of standardized procedures and accuracy.

• Operated and maintained analytical instruments for sample testing and analysis.
• Collaborated with team members to ensure compliance with national safety standards.
• Contributed to process improvements to enhance testing efficiency and accuracy.
