Photolithography Process Engineer – Advanced Packaging & MEMS

SkyWater Technology; Kissimmee (FL); On-site; USD 114,000 - 171,000; Full time

Job summary

SkyWater Technology in Florida is seeking a Lithography Engineer to develop, optimize, and transfer lithography processes for advanced packaging and MEMS/photonic devices. You will work with process and equipment engineers to ensure robust, manufacturable solutions that meet CD, overlay, and defectivity targets.

The role requires hands-on semiconductor fab experience, strong problem-solving, and data-driven process improvements.

Qualifications

• Hands-on semiconductor fab processing experience with a strong understanding of lithography processes and equipment.
• Experience with conventional photolithography processes including resist coating, soft bake, exposure, post-exposure bake, development, and resist strip.
• Experience with a variety of lithography platforms and exposure technologies, including mask-based, direct-write, and maskless lithography.
• Understanding of lithography process parameters including critical dimension, overlay, focus, dose, resist thickness, pattern fidelity, resolution, defectivity, and process window.

Responsibilities

• 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 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 methodologies.
• Partner with equipment and process engineers to troubleshoot lithography tool performance and improve equipment/process capability.
• Support new product introduction, customer-specific process development, and technology transfers into manufacturing.
• Collaborate with integration and device teams to understand lithography requirements and translate device designs into manufacturable process solutions.
• Monitor electrical test parametrics and correlate lithography process performance with downstream device and package performance.
• Develop process control strategies and recommend appropriate metrology and monitoring plans for lithography processes.
• Prepare technical reports, presentations, process documentation, and development summaries for customers, colleagues, and management.
• Participate in cross-functional problem-solving teams and lead lithography-related improvement projects.
