Position Summary:

We are looking for a hardworking, passionate, and experienced Lithography Engineer to support our Florida Advanced Packaging site. In this role, you will be responsible for the development, optimization, integration, and continuous improvement of lithography processes used in advanced semiconductor packaging and MEMS/Photonic device manufacturing.

The Lithography Engineer will work closely with process engineers, equipment engineers, integration teams, and foundry customers to develop robust, manufacturable lithography processes that meet critical dimension, overlay, defectivity, and patterning requirements. The ideal candidate will have strong semiconductor fab processing experience, excellent problem-solving skills, and the ability to use data-driven methods to improve process capability, yield, and device performance.

Excellent oral and written communication skills are required to effectively communicate technical concepts, development results, and recommendations to customers, colleagues, and management.

Major Area of Accountability:

• Develop, optimize, transfer, and integrate lithography processes in a high-volume or advanced semiconductor manufacturing environment.
• Develop and qualify robust, manufacturable photoresist and patterning processes for advanced packaging, MEMS, and photonic device applications.
• Optimize lithography process conditions including resist coating, baking, exposure, development, descum, and associated process steps.
• Develop and optimize exposure recipes to achieve required critical dimensions, pattern fidelity, overlay, and process margins.
• Support process integration of lithography with deposition, etch, CMP, metallization, and dielectric processes.
• Develop and maintain lithography process specifications, operating windows, process recipes, and documentation.
• Utilize CD-SEM, optical metrology, profilometry, overlay metrology, defect inspection, and other characterization techniques to evaluate lithography performance.
• Conduct Design of Experiments (DOE) to identify key process parameters and establish robust operating windows.
• Analyze process data to identify sources of variation, process marginalities, and opportunities for continuous improvement.
• Monitor inline and end-of-line SPC charts for trends, excursions, and abnormal process behavior.
• Investigate lithography-related defects, patterning failures, CD variation, overlay errors, and yield losses using structured problem-solving…
