Photolithography Engineer

Job Title

Photolithography Engineer

Role Summary

Responsible for resolving lithography scribe and overlay challenges for memory devices by running optical simulations, recommending mark designs, performing root-cause analysis, and delivering training to photolithography engineers.

Lead and define projects to close photolithography performance gaps across current and future memory and storage nodes; collaborate with vendor application teams, process development, and cross-functional stakeholders.

Experience Level

Mid-level (Mid-Career). No explicit years-of-experience were provided.

Responsibilities

Key duties include modeling, project leadership, and cross-functional collaboration to improve photolithography overlay and scribe performance.

• Establish project plans to address overlay challenges for current and near-term nodes (N, N+1, N+2).
• Perform optical simulations related to scribe and overlay; provide mark design recommendations.
• Work with vendor application teams to identify and implement overlay scribe improvements.
• Define and lead sophisticated, multi-disciplinary projects essential to the photolithography roadmap.
• Standardize methods and procedures across the area, department, and FABs.
• Investigate and identify root causes for complex lithography problems; summarize findings in written reports.
• Provide training and mentorship to other photolithography engineers on simulation and best practices.
• Advise senior management on technical issues related to overlay and scribe marks.
• Build and maintain strong relationships with internal stakeholders and suppliers to align expectations and deliverables.
• Integrate AI-assisted tools into daily work to improve efficiency and quality; evaluate and share AI-enabled improvements within scope of work.

Requirements

Core technical skills, practical experience, and communication abilities required for the role. Degree requirements are listed separately below.

• Must-have: Strong understanding of photolithography principles and optical metrology.
• Must-have: Knowledge of how lens aberrations, scanner chuck differences, and process variations affect overlay.
• Must-have: Familiarity with alignment and overlay mark types and how mark design impacts overlay errors.
• Must-have: Strong written, verbal and presentation skills; ability to summarize experimental plans and results.
• Must-have: Ability to work cross-functionally and maintain relationships with multi-functional teams and suppliers.
• Must-have: Curiosity for R&D and ability to translate research into production-worthy solutions.
• Must-have: Baseline digital fluency and role-appropriate AI literacy to use AI-enabled tools responsibly and effectively.
• Nice-to-have: Experience with overlay mark simulation software.
• Nice-to-have: Familiarity with semiconductor process integration.

Education Requirements

B.S. in Engineering with an emphasis on Lithography will be considered.
