Introduction

As a Lithography Process Engineer, you will be responsible for sustaining, optimizing, and developing photolithography processes in a high-volume manufacturing environment. You will work with advanced lithography tools and metrology systems to ensure critical dimension (CD) control, overlay accuracy, and defect reduction.

Your Job

• Monitor and analyze SPC/ESPC charts for lithography modules using SPACE; respond to OOC/OOS events.
• Perform critical dimension (CD) and overlay analysis using CD-SEM, scatterometry, and overlay metrology tools (e.g., KLA, ASML YieldStar).
• Optimize photoresist coating, soft bake, exposure, post-exposure bake (PEB), and development processes.
• Manage and tune stepper/scanner exposure tools (e.g., ASML, Nikon) for optimal performance and tool matching.
• Conduct Design of Experiments (DOE) and split lot analysis using JMP, Klarity ACE, and other statistical tools.
• Troubleshoot lithography defects such as bridging, footing, scumming, and resist residues.
• Collaborate with Equipment Engineers on tool qualification, focus-exposure matrix (FEM), and process window optimization.
• Maintain and optimize reticle management, focus and exposure control, and alignment strategies.
• Drive process improvements to enhance CD uniformity, overlay performance, line edge roughness (LER), and critical dimension uniformity (CDU).
• Support technology transfers, new product introductions (NPI), and process ramp-up activities.
• Lead cross-functional teams to resolve yield excursions and implement corrective/preventive actions (CAPA).
• Ensure compliance with TS16949 and other quality standards through regular audits and documentation updates.
• Perform all activities in a safe and responsible manner and support all Environmental, Health, Safety & Security requirements and programs.

Required Qualifications

• Bachelor’s degree in Electrical / Electronics / Mechanical / Mechatronics / Microelectronics Engineering.
• 1 to 3 years of relevant experience in semiconductor wafer process engineering.
• Proven ability to identify, assess, and solve problems.
• Ability to perform Normal / Swing Shift (or 12-hour rotating shift if required).
