Senior Photolithography Process Development Engineer

About our group:

Process Technology Development (PTD) is responsible for developing and integrating next-generation slider manufacturing technologies to support Seagate’s future recording product roadmap. Our mission is to develop, mature, and industrialize advanced process solutions that improve critical-to-quality (CTQ) performance, yield, automation, scalability, and manufacturing competitiveness.

As part of the Slider Modernization initiative, we are transforming legacy photolithography and pattern transfer processes into an advanced, highly automated, micro-patterning-capable manufacturing platform. This includes the development of next-generation lithography equipment, spray coating technologies, advanced photoresists, intelligent process control, and modern pattern transfer solutions to enable future HMS and next-generation slider architectures.

About the role - you will:

• Develop and deploy next-generation photolithography technologies to support future slider product roadmaps and Slider Modernization initiatives.
• Support advanced micro-patterning capability development, including stepper lithography, spray coating, spray development, resist technologies, and pattern transfer solutions.
• Perform technical evaluations and support the installation, qualification, and technology readiness of new photolithography platforms, including exposure tools, track systems, resist processing modules, and automation solutions.
• Develop and optimize lithography processes for critical slider features requiring improved resolution, overlay accuracy, critical dimension control, and process capability.
• Collaborate with design, process integration, metrology, milling, cleanliness, automation, manufacturing, and equipment engineering teams to enable successful technology introduction.
• Define and execute engineering experiments, DOE plans, process characterization studies, and learning cycles to understand process mechanisms and optimize performance.
• Develop process windows, control strategies, and CTQ monitoring methodologies to support robust and scalable process solutions.
• Work with equipment suppliers, research institutes, and external technology partners to evaluate emerging lithography solutions and support technology development.
• Conduct technology benchmarking across the semiconductor, MEMS, and advanced nanofabrication industries to identify best-known methods and potential improvement opportunities.
• Provide technical input for roadmap planning, business cases, technology investment proposals, and capital equipment evaluations related to future lithography capability expansion.
• Work closely with process, operations, and equipment engineers to drive technical excellence in lithography, pattern transfer, and process integration.
• Support cross-site and cross-functional technology transfer activities to enable successful process development and deployment across Seagate operations.
• Document technical findings, experimental results, risks, and recommendations, and communicate them clearly to relevant stakeholders.
